Let's look back at a 2017 trade between White Sox, Yankees

David Robertson

Whenever veteran players are traded for prospects, we always say we have to wait four or five years until we can fully judge the trade.

Well, more than five years have passed since the White Sox swung a seven-player deal with the New York Yankees on July 19, 2017.

New York received:

• 3B Todd Frazier
• RHP David Robertson
• RHP Tommy Kahnle

White Sox received:

• OF Blake Rutherford
• RHP Tyler Clippard
• OF Tito Polo
• LHP Ian Clarkin 

Ugh. You can see where this is going. It will probably go down as one of Sox GM Rick Hahn's worst deals. This trade has been in the news recently, because Rutherford recently signed a minor-league deal to join the Washington Nationals. Now that he has left the Sox, all the players they acquired in this trade are gone from the organization.

Here's a look at how each player involved in this trade has fared since that day in July:

Frazier. The veteran third baseman played 66 games with the Yankees and hit 11 homers while batting .222. That's similar to the performance he had with the Sox -- good power, but not much average. He eventually signed a two-year contract with the New York Mets and hit a combined 39 homers for them in the 2018 and 2019 seasons. Frazier split time between the Texas Rangers and Mets in 2020, batting .236 with four homers in the pandemic-shortened season. He played briefly with the Pittsburgh Pirates in 2021, but he was done at that point. He was released and retired.

Robertson. The relief pitcher did well for the Yankees, going 5-0 with a 1.03 ERA in 30 games after joining them in 2017. He appeared in 69 games for the 2018 Yankees. He went 8-3 with a 3.23 ERA and five saves. Robertson has bounced around the league since then -- Philadelphia, Tampa Bay, the Cubs, then back to Philadelphia again. He pitched four scoreless innings with one save for the Phillies during the 2022 World Series. This offseason, he signed a free-agent deal with the Mets.

Kahnle. Would you believe it if I told you that Kahnle is still a Yankee? He's on his second stint with the team. He pitched in 129 games for New York from 2017-20. He was 6-3 with a 4.01 ERA over that time, working mostly in middle relief. Elbow surgery sidelined him for all of 2021, but he resurfaced with the Los Angeles Dodgers in 2022. He pitched 13 games (2.84 ERA), did enough to prove he was healthy and signed a one-year deal to return to the Yankees in 2023.

Clippard. The veteran reliever is the only one of the four players the Sox acquired in the trade to play for the major league club. He pitched in 11 games for the 2017 Sox, recording two saves. After roughly three weeks in a Sox uniform, he was traded to the Houston Astros for cash considerations as part of a waiver deal. He's since bounced around the league -- Toronto, Cleveland, Minnesota, Arizona, Washington. The Nationals let him go last August. At age 37, his career is likely over.

Polo. By 2019, Polo was out of the Sox organization. He was in Double-A Birmingham in 2018, where he batted .245. The last time he was in affiliated ball was 2019, at Triple-A Tacoma in the Seattle organization. Since then, he's been playing for assorted teams in the Mexican League.

Clarkin. The left-hander last pitched in the Sox organization in 2019, at Class-A Winston-Salem. The Sox designated him for assignment and tried to sneak him through waivers, but he got claimed by the Cubs. For the past two years, he's pitched in the Colorado organization. He had a 8.77 ERA last season in 17 games at the Triple-A level.

Rutherford. The left-handed hitting outfielder was a consensus top 50 prospect at the time of this trade, and hey, at least he hung around in the Sox organization through 2022! Unfortunately, he wasn't good enough defensively to cover center field, and he never developed the pull-side power necessary to be a good corner outfielder. Rutherford, who turns 26 this May, simply lacks a carrying tool that will lift him about Quad-A status. In two seasons at Triple-A Charlotte, he batted .260/.298/.416, but he hit only 24 homers despite playing in a notoriously hitter-friendly park. Without question, the Sox have had a need at corner outfield over the past few years, but Rutherford was never good enough to merit a look. That about says it all.

In the final analysis, the Sox accomplished little with this trade other than offloading a bunch of salary. Frazier, Robertson and Kahnle were all assets to varying degrees, and it's unfortunate the Sox didn't get any production from the players they received in this deal.

Everyone else has a top 10 White Sox prospects list -- why shouldn't I?

Luis Robert

This is the time of year when we see a lot of publications updating their prospects lists, both for individual teams and the league in general.

The White Sox have a top-heavy farm system, and the higher-end guys figure to graduate to the majors sometime in 2020. No. 1 to No. 4 on their prospect list seems obvious to most people. It's those spots from No. 5 to No. 10 that are the subject of debate.

Since everyone else seems to be taking a kick at the can at how these guys should rate, why shouldn't I throw my two cents in? Here are my top 10 Sox prospects going into the 2020 season:

1. Luis Robert, CF. Duh, right? Robert will not be on these lists much longer. He will start the season as the Opening Day center fielder in Chicago. He's the consensus top prospect in the organization, and he ranks anywhere from No. 2 to No. 6 when you see rankings of the top prospects in all of baseball.

I wish Robert would have been called to the majors last season. His tools are insane -- power, speed, defense, throwing arm -- there's nothing to complain about in any of those areas. The main problem for Robert is he remains a bit of a wild swinger, and I expect MLB pitchers to exploit that early in his career. Eventually, he'll make the adjustment, but I wanted that learning curve to start in 2019, during games that were inconsequential in the standings.

Now, Robert will have to learn in the 2020 season, during which the Sox have expectations of being much more competitive. We'll see how he holds up. Certainly, there's nothing left to prove in minor-league levels. Robert hit .328/.376/.624 with 32 home runs and 36 steals across three levels last year. Yep, he's ready for his shot.

2. Michael Kopech, RHP. Kopech is a year and a half removed from elbow surgery. His fastball is back where it should be, sitting between 95 and 100 mph. Will the command be there after such a long layoff from competitive ball? Maybe not, but given Kopech's big fastball and his quality secondary pitches -- including a slider and a change -- I don't have any doubt he's one of the five best starting pitchers the Sox have.

But, the Sox will show "an abundance of caution" with Kopech. He's going to start the year in Triple-A Charlotte, but I don't expect him to be there for long. I'd be stunned if he isn't in Chicago by June 1, assuming good health. Even though the Sox insist that Kopech isn't on an innings limit this season, we know they aren't going to overtax him, so I just assume he throw his innings with the Sox later in the season, as opposed to early in the cold, rainy weather in April.

3. Andrew Vaughn, 1B. The third overall pick in the 2019 draft hit his first spring training home run on Friday, and he appears slated to start the season in Double-A Birmingham. Vaughn put up monstrous numbers over three collegiate seasons at California; his career slash line there was .374/.495/.688.

Unlike some other Sox prospects, Vaughn seems willing to take a walk. He had a .384 OBP in 55 games in the Sox's minor-league system in 2019. He has a simple swing and a disciplined approach that will make pitchers work. Obviously, as someone who is limited to first base as a defender, he'll have to hit to stick in the majors. But there's no reason to believe he won't. Maybe we'll see him at the end of 2020, or in 2021.

4. Nick Madrigal, 2B. He won't hit for power, no, but I'm not sure why I should be concerned about that. In a projected lineup that includes Jose Abreu, Eloy Jimenez, Robert, Edwin Encarnacion, Yoan Moncada and Yasmani Grandal, do the Sox need Madrigal to hit balls off the wall and over it? Not in my world.

I'd make Madrigal the starting second baseman from Opening Day on this season. He can field the position at an elite level, and he almost never strikes out -- you may have heard he only struck out 16 times in 532 plate appearances in 2019. He hit .311/.377/.414 across three levels last season, so I don't think there's a whole heckuva lot for him to prove in the minors. I hope the Sox don't send him back to the minors for service time reasons. We should be past that point in the rebuild.

5. Jonathan Stiever, RHP. I'm always wary of hyping guys over 10 or 12 good starts, but I ended up putting Stiever at No. 5 on this list mostly because his good health (knock on wood) separates him from other Sox prospects. Stiever had a rough start to 2019 at Class-A Kannapolis, where he went 4-6 with a 4.74 ERA in 14 starts.

But something clicked when Stiever got promoted to High-A Winston-Salem, where he went 6-4 with a 2.15 ERA across 12 starts. Stiever's fastball sits in the low 90s, and he's got a good curve. His slider and change are just average, so can he develop a third pitch? And are the gains he made last season sustainable? Stiever figures to start the season in Double-A Birmingham.

6. Dane Dunning, RHP. I had thoughts of putting Dunning at No. 5 on this list, because I'm reasonable certain he'll contribute at the MLB level once he gets healthy. I don't think he has the upside Stiever has, however, and these lists often are about upside. Dunning is recovering from Tommy John surgery and hopes to return to affiliated ball by about June 1.

We could see Dunning in Chicago by the second half of this season. While he's not going to overpower anybody, he has three pitches he can throw for strikes, and well, that's something. A lot of times, guys can stick at the back of the rotation if they can consistently pound the zone with multiple pitches.

7. Luis Alexander Basabe, OF. Basabe's breakout 2018 that saw him hit 15 home runs and earn a spot in the Futures Game has not been forgotten, despite an injury-plagued 2019 season. A broken hamate bone robbed him of his power last season, when he hit only three home runs.

Basabe's slash line last year was .246/.324/.336, and certainly, Birmingham is not a good place for hitters. But, other Sox prospects have produced for the Barons on their way to the majors, and Basabe needs to do the same. The key is lowering his strikeout rate, which was hovering about 30 percent throughout much of last season. Basabe has speed and good defensive tools, so the question is whether the bat comes around.

8. Zack Collins, C. Collins has to get some points because he made it to the majors last season, although his questionable defensive skills behind the plate are likely to send him back to Triple-A to start 2020. Collins received two opportunities in Chicago in 2019, and the first was a disaster. He went 2 for 26 in nine games and got sent back down.

When he came back in September, he had made some adjustments, and it looked better. He slashed .233/.343/.417 with two homers, three doubles, a triple, nine RBIs and nine walks in 71 plate appearances. He also struck out 25 times, which remains a concern, but you figure the Sox will be slow to give up on a left-handed bat and a former first-round draft pick.

9. Blake Rutherford, OF. Hey, let's go wishcasting here. I asked about Rutherford at SoxFest, and director of player development Chris Getz expressed optimism that Rutherford started to turn a corner the second half of last season at Double-A Birmingham. He hit .307/.364/.404 over the last three months of 2019.

That wasn't enough to erase the hideous .185/.226/.291 line he had going into June. We'll keep an eye on Rutherford early in the season to see if he can hold onto his second-half gains. One big problem: He lacks the defensive skill set to play anything other than a corner outfield spot, and he has little power -- only seven home runs last season. He's added 10 to 12 pounds over the offseason, and we'll see if that makes a difference.

10. Matt Thompson, RHP. Just for grins, let's throw a high school pitcher in here, if for no other reason that I'm not high on anybody else. Thompson was the Sox's second-round pick in 2019, and some struggles during his senior season allegedly caused him to take a tumble out of the first round. He's an athletic pitcher with a mid-90s fastball, so we'll see where that goes in the coming years. Realistically, a guy drafted out of high school needs at least four years to make the majors.

White Sox part ways with Omar Vizquel, add 7 to 40-man roster

Omar Vizquel

The White Sox on Wednesday announced that Omar Vizquel will not be returning as a manager in their minor league system for the 2020 season.

Vizquel enjoyed his best success as a manager during the 2018 season, when he led High-A Winston-Salem to an 84-54 record and a first-half division championship. He was named Carolina League Manager of the Year.

In 2019, Vizquel was promoted to manage Double-A Birmingham, but he was unable to duplicate that same success. The Barons finished 64-72.

"We felt that it was best for both sides to make a change," Chris Getz, White Sox director of player development, told MLB.com. "Listen, Omar, ultra-talented player, very good instructor, created a good environment for our players. We just felt with where things are at, our player development system, that it was time to go separate ways. But not only for himself, but for the organization as well and we wish Omar well. He was a positive influence while he was here."

The Sox fan reaction to this news has been overwhelmingly negative, and frankly, I'm a little surprised. Vizquel's team had a subpar year, and several outfield prospects of note -- Blake Rutherford, Luis Gonzalez, Luis Alexander Basabe and Micker Adolfo -- stalled this season. To be fair, Adolfo got hurt again, and what's a manager to do? But expectations were higher for this Birmingham group in 2019.

In general, I think the fan discontent stems from the long-held belief that Vizquel would eventually replace Rick Renteria as the manager in Chicago. I've never quite understood why that was the assumption, nor have I understood why it is just assumed that Vizquel would do a better job than Renteria has.

Clearly, Vizquel had a better playing career than Renteria, but that doesn't amount to a hill of beans when evaluating someone as a manager.

I'm left to conclude that some fans simply want Renteria gone. They believe anyone would be better, and they're just pissed off that Vizquel is no longer an option.

Sox add 7 players to 40-man roster

Rutherford, catcher Yermin Mercedes and pitchers Dane Dunning, Jimmy Lambert, Zack Burdi, Matt Foster and Bernardo Flores had their contracts purchased by the Sox on Wednesday. The seven players were added to the 40-man roster, bringing the roster to the maximum 40.

As a result, these men are not available to other clubs in the Rule 5 draft. Notable players who were not protected included pitchers Alec Hansen, Zach Thompson and Spencer Adams.

Mercedes was the big question mark. He batted .317/.388/.581 with 23 home runs and 80 RBIs in stops at Birmingham and Triple-A Charlotte. He can hit, but he's poor defensively, and that seemed to be preventing him from getting a call to the majors.

If he had been exposed in the Rule 5 draft, it seems likely that a rebuilding team would have snagged him and given him a chance as a designated hitter. Now, he'll stay in the Sox organization, but the club has a logjam at catcher.

Even with Welington Castillo gone, there are four catchers on the 40-man -- James McCann, Zack Collins, Seby Zavala and Mercedes. It wouldn't be surprising to see a trade of one of these players who is not named McCann -- who is the presumed starter in 2020.

For me, Dunning, Lambert and Burdi are the no-brainers here. All three pitchers are coming off injuries, yes, but that would be all the more reason for a rival club to snag them in the Rule 5 draft and hide them on the injured list for half a season.

Dunning is the No. 5 prospect in the organization. Lambert ranks 18th and was thought to have a chance to make the majors in 2019 before he got hurt. Burdi is a former first-round draft pick.

Too much has been invested in these three players to risk losing them for nothing.

White Sox prospect Luis Robert injures thumb (again)

Can someone on the White Sox's coaching staff please teach Luis Robert how to slide?

The prized outfield prospect is once again injured, having hurt his thumb sliding head-first into second base on a stolen base attempt Saturday during an intrasquad game.

This is the third time Robert has hurt his thumb in the past 12 months. He first got hurt on a slide during spring training last year, and he reinjured the thumb on July 3 of last season.

Robert played in only 50 games in 2018; the injuries cost the 21-year-old valuable development time.

Fortunately, this injury is not thought to be serious. The team expects him to return to game action as soon as Thursday.

Sox manager Rick Renteria said Robert wasn't supposed to be trying to steal in the intrasquad game. He apparently made the attempt on his own. Renteria said the youngster was guilty of a "lapse in his own judgment."

I do applaud the Sox coaches for not wanting Robert to take risks on the base paths in meaningless games. However, it's clear he needs to be coached on his technique.

This is a player who is important to the Sox's rebuild. Fix this problem, so that Robert can stay on the field.

Madrigal among first cuts

The Sox made their first roster cuts of the spring Tuesday. Nick Madrigal, the team's No. 1 pick in the 2018 draft, was among the players reassigned to minor-league camp.

Outfielders Blake Rutherford and Luis Gonzalez and left-handed pitchers Jordan Guerrero and Bernardo Flores also are headed to minor-league camp.

Latest statistics for notable White Sox prospects

I haven't checked in on the farm lately, so with the calendar turning to May, perhaps the timing is right to see how some notable White Sox prospects have fared through the first month of the season.

There has been one notable promotion so far, with right-handed pitcher Dane Dunning moving up from High-A Winston-Salem to Double-AA Birmingham, where he won his first start.

Also of note, former first-round draft pick Zack Collins was just named the Southern League Player of the Week. Thank goodness, because Collins had been really struggling at Birmingham. He raised his overall batting average from .054 to .206 in week that saw him post a .438 average with a homer, a stolen base, six RBIs and six walks.

Baseball America releases list of top-10 White Sox prospects

Eloy Jimenez

For those who enjoy lists, Baseball America has released its latest list of top-10 White Sox prospects. You would need to buy a subscription from that publication to get full details, but here is its ranking:

1. Eloy Jimenez, OF
2. Michael Kopech, RHP
3. Alec Hansen, RHP
4. Luis Robert, OF
5. Dane Dunning, RHP
6. Zack Collins, C
7. Jake Burger, 3B
8. Blake Rutherford, OF
9. Gavin Sheets, 1B
10. Dylan Cease, RHP

Notable graduations from last year's Baseball America list at this same time include the guys who were ranked 1, 2 and 3: Yoan Moncada, Lucas Giolito and Reynaldo Lopez. All received call-ups to the big leagues during the 2017 season.

Baseball America says the top of the Sox's farm system ranks among the best in the game, and the top 10 could get stronger if Burger and Sheets -- both members of the 2017 draft class -- play well in their first full seasons as professionals.

The publication also notes that there is a bit of a dropoff in the Sox's system once you get past the first 15 prospects. The depth could be better if more fringe prospects such as Luis Alexander Basabe and Alex Call bounce back from disappointing 2017 seasons.

Here's the best-of list for the Sox's farm system provided by Baseball America:
Best hitter for average: Jimenez
Best power hitter: Jimenez
Best plate discipline: Collins
Fastest base runner: Logan Taylor
Best athlete: Robert
Best fastball: Kopech
Best curve: Hansen
Best slider: Zack Burdi
Best changeup: A.J. Puckett
Best control: Dunning
Best defensive catcher: Nate Nolan
Best defensive infielder: Yeyson Yrizarri
Best infield arm: Zach Remillard
Best defensive outfielder: Basabe
Best outfield arm: Micker Adolfo

Former White Sox relievers among Yankees heroes in AL wild card game

David Robertson

Tuesday's American League wild card game was not decided by starting pitchers.

Both Luis Severino of the New York Yankees and Ervin Santana of the Minnesota Twins were terrible.

Severino lasted 29 pitches. He recorded only one out in the top of the first inning and left the mound with his team trailing 3-0 and runners on second and third. Santana wasn't much better for Minnesota, allowing four earned runs over only two innings.

Nope, this one was decided by the bullpens, and New York's relief corps came through with 8.2 innings of one-run ball in an 8-4 Yankees victory.

Didi Gregorius, Brett Gardner and Aaron Judge homered for New York, but two of the players who had the biggest say in the outcome of this game were two relievers the Yankees acquired from the White Sox in July -- David Robertson and Tommy Kahnle.

The two right-handers combined for 5.2 innings of scoreless ball and six strikeouts. Robertson entered in an unfamiliar role -- he came on in the third inning with the Yankees leading 4-3. The Twins had the bases loaded with one out. Robertson allowed only one of the inherited runners to score -- when Byron Buxton narrowly beat out a potential inning-ending double play ball.

The former Sox closer then held the Twins at bay until there were two outs in the sixth inning, during which time the Yankees built a 7-4 lead against the Minnesota bullpen.

Kahnle then came in and retired all seven of the Twins hitters he faced to get New York through eight innings with a lead. Aroldis Chapman struck out the side in the ninth, and the Yankees are in the ALDS to face the Cleveland Indians.

Robertson picked up the win, and the 3.1 innings pitched is a new career high for him. He has been a terrific midseason acquisition for the Yankees. In 30 regular-season games, he pitched 35 innings, struck out 51 batters and went 5-0 with a 1.03 ERA and 0.743 WHIP. He did not allow a run in 15 September innings, and carried over his lights-out pitching into the wild card game.

The July trade with the Sox has paid immediate dividends for the Yankees. If not for Robertson and Kahnle, perhaps their season would be over today.

We can only hope that the prospects the Sox got from New York in that trade -- outfielders Blake Rutherford and Tito Polo and pitcher Ian Clarkin -- can one day come through in the clutch in a future big game on the South Side of Chicago.

White Sox trade Todd Frazier, David Robertson, Tommy Kahnle to Yankees

David Robertson

The seven-player trade between the White Sox and the New York Yankees was a foregone conclusion by the time it was announced late Tuesday night.

Todd Frazier was seen giving teammates goodbye hugs before the Sox played the Los Angeles Dodgers, and neither David Robertson nor Tommy Kahnle were summoned from the bullpen in the high-leverage relief situations that arose in the Sox's 1-0 loss.

After the game, it was announced that Frazier, Robertson and Kahnle were dealt to the Yankees in exchange for outfielders Blake Rutherford and Tito Polo and pitchers Ian Clarkin and Tyler Clippard.

Here's a summary for each of the players the Sox received:

Rutherford: This is the best prospect in the deal. He was the Yankees' first-round draft pick in 2016, and he's ranked 36th on Baseball America's midseason top-100 prospect rankings. He was hitting .281/.342/.391 at Class-A Charleston with 20 doubles, two home runs and 30 RBIs in 304 at-bats.

Clarkin: The 22-year-old left-hander has been frequently injured since he was drafted out of high school in 2013, but he's managed to stay healthy enough to post a 2.61 ERA over 72.1 innings for Class-A Tampa this season.

Polo: The 22-year-old outfielder has split time between Class-A Tampa and Double-A Trenton this year, and has hit .298/.358/.446. He's also got 25 stolen bases in 31 attempts.

Clippard: The 32-year-old veteran reliever is 1-5 with a 4.95 ERA in 40 appearances with the Yankees this year. He's got an expiring contract, and the Sox will use him to close games in Robertson's absence, on the rare occasion where they actually have a lead going into the ninth inning. Hey, somebody has gotta pitch.

This deal is almost like two trades in one. The way I see it, Robertson and Kahnle were traded for the three prospects. Robertson is owed about $20 million until his contract is up at the end of the 2018 season. The Yankees are taking all that salary on, so he alone wouldn't have been enough to net a top-50 prospect such as Rutherford. Throw Kahnle into the deal, and now the Yankees add two quality pieces to their bullpen, and they are willing to part with a better quality young player.

The other part of the deal is basically Frazier for Clippard. Two underperforming veterans on expiring contracts. Basically, you have each team saying to the other, "Go ahead and take this guy, and maybe he'll do better for you than he did for us."

Clippard takes Robertson's spot on the roster. The leaves two other openings. One is going to relief pitcher Brad Goldberg. The other is going to some young infield prospect named Yoan Moncada. You might have heard of him.
