A's acquire Jeff Samardzija, Jason Hammel from Cubs

The Oakland A's on Friday fortified themselves for a potential World Series run, strengthening their starting rotation by acquiring pitchers Jeff Samardzija and Jason Hammel from the Cubs. In return, Chicago will receive a pair of former first-round draft picks, shortstop Addison Russell (2012) and outfielder Billy McKinney (2013), plus pitcher Dan Straily and a player to be named later.

Samardzija, 29, went 2-7 for the Cubs with a 2.83 ERA this season. He has one more year of arbitration before becoming eligible for free agency. Hammel, 31, beat the Washington Nationals just hours before being traded on Friday. His tenure with the Cubs ends with an 8-5 record and 2.98 ERA. He will be a free agent at the end of the season.

Russell is one of the top-rated prospects in all of baseball, but a hamstring strain has limited him to just 18 games this season. The 20-year-old was hitting .333 in 58 at-bats for Double-A Midland at the time of the deal. McKinney, 19, was hitting .241 with 10 home runs and 33 RBIs in 75 games for Class-A Stockton.

Straily, 25, is the one player the Cubs got with big league experience in this deal. He's made 41 starts for Oakland over the past three years, going 13-11. Seven of those starts were this year. He was ineffective, going 1-2 with a 4.93 ERA before being sent back to Triple-A Sacramento, where he was 4-3 with a 4.71 ERA.

I like this move by the A's. It's bold and uncharacteristic for them. They are usually the team stockpiling prospects, but obviously their front office senses their time to win is right now. They've got the best record in an American League that lacks a clear favorite, and adding two solid pitchers to their rotation could be the move that swings the pendulum in their favor.

And make no mistake about it -- Oakland needed to add something to its rotation. While the A's have been among the league ERA leaders all year, injuries have left them thin. Jarrod Parker and A.J. Griffin have been lost for the year. Sonny Gray is a good, young arm, but he's never pitched a full season in the big leagues. Jesse Chavez has been a nice stopgap, but I'm not sure he's the kind of guy you want to send to the mound to start a playoff game. Scott Kazmir has also thrown the ball well this season, but he hasn't pitched more than 158 innings in a season since 2008.

There are question marks abound there, and I think veteran workhorses like Samardzija and Hammel can provide the answers for Oakland. And, in Samardzija's case, he might get a new lease on life being paroled from the perpetually rebuilding Cubs. With this move, the A's will be in better shape to match up pitcher-for-pitcher against a team like Detroit in a short playoff series.

As for the Cubs, well, we'll see how this move works out for them sometime around 2018. Straily is still young enough that he could get better, but his track record suggests back of the rotation. He's the only one of these three guys we'll be seeing in the big leagues soon.

The reports about Russell are glowing, but obviously there are still a lot of development at-bats in the minor leagues in his future. McKinney is only 19 years old, and he's struggled in high-A, which is understandable because he's playing against older players in that league.

What's interesting about this deal from a Cubs perspective is they added another shortstop in Russell. Their incumbent shortstop, Starlin Castro, is one of the few legitimate big league hitters they've got. And, they've got highly regarded prospect Javier Baez waiting in the wings at Triple A at that position. Now, they've got yet another "shortstop of the future" in their organization.

Obviously, all three of these guys can't play shortstop together at Wrigley Field, so that means one of two things has to happen -- position changes or trades. The Cubs don't have much in the way of elite pitching prospects in their system, and I'm somewhat surprised they didn't get a highly regarded pitching prospect as part of their return for Samardzija.

But, now they've got a glut of shortstops. Would they trade one or more of these guys to restock their pitching depth? That would seem to make sense. We shall see.

Chris Sale dominates Mariners lefties on Fourth of July

Here's a fun fact about White Sox ace Chris Sale: He has four starts this season where he has recorded 10 or more strikeouts while allowing one earned run or less. He is the only White Sox pitcher to accomplish that in the past 100 years, and we've still got almost half a season to go.

Sale latest dominant outing came Friday night in the opener of a three-game series against the Seattle Mariners. The left-hander improved to 8-1 on the season in the Sox' 7-1 victory. It was Sale's second complete game of the year. He struck out a season-high 12, walked nobody and allowed just six hits. The Mariners did not score a run until the ninth inning, when the outcome was no longer in doubt.

I'll be honest: This was an extremely favorable matchup for Sale. It's not that the Mariners aren't a good team. They are, as their 47-39 record will attest. But when I saw the Seattle lineup, I noted the Mariners had six left-handed hitters in there -- James Jones, Robinson Cano, Kyle Seager, Logan Morrison, Michael Saunders and Dustin Ackley.

Coming into Friday's action, left-handed hitters were posting an anemic .089/.196/.089 slash line against Sale. In fact, lefties had managed just four hits (all singles) off Sale all season.

Yeah, this wasn't going to end well for the Mariners. But give Seattle credit: its lefties went 4 for 21 in Friday's game, and Cano managed the first extra-base hit for a left-handed hitter off Sale all season. It was a bloop double in the ninth that should have been caught by Sox left fielder Dayan Viciedo, but it still counts.

Nevertheless, the Mariners had no prayer of mounting a consistent attack with that left-hand dominant lineup. As TV analyst Steve Stone noted in the ninth inning on Friday, Seattle could have played this game 20 times and it probably would have lost it all 20 times.

I was looking at the Mariners' roster, and I can't blame manager Lloyd McClendon for stacking his lineup with lefties. He's only got four right-handed hitters on his team. He played three of them -- Corey Hart, Mike Zunino and Willie Bloomquist. The fourth, John Buck, is the backup catcher to Zunino.

McClendon played the cards he had. Against Sale, it was a losing hand.

White Sox prospect update

Thursday is an off-day for the White Sox, so let's take a moment to update the activities of some of the top prospects in the organization.

1. Matt Davidson, 3B, Charlotte -- Davidson continued his hottest stretch of the season on Wednesday, going 2-for-5 with two doubles for the Knights. He hit two home runs in the second game of a doubleheader on Monday night, including a walk-off blast in the 10th inning that lifted Charlotte to a 7-5 win. Davidson had an extremely poor first two months, so his overall slash line looks sickly: .206/.282/.419. But he hit .353 over his last 10 games in June. He homered nine times during the month, and now ranks second in the International League with 15 home runs. At least he's trending in the right direction.

2. Micah Johnson, 2B, Charlotte -- The "game changer" started the year at Double-A Birmingham and dominated opposing pitchers, posting a .329/.414/.466 slash with three homers, 16 RBIs and 10 steals in 37 games. Since his promotion to Charlotte, the numbers are a little more modest: .272/.303/.353 with a homer, 15 RBIs and five steals in 31 games. To be fair, there's often an adjustment period when a player is promoted to the next level, and that's been the case for Johnson. He's highly regarded enough that he was named to the U.S. roster for the Futures Game. It wouldn't be shocking if he gets a September callup this year. Scouts rank his speed as an 80 on the 20-to-80 scale, so that tool combined with his decent-to-good bat will likely get him to the majors. The question is, is he a second baseman or an outfielder moving forward?

3. Tim Anderson, SS, Winston-Salem -- The Sox recently got bad news on Anderson, who was hit by a pitch and will miss four to six weeks with a fracture in his right wrist. Anderson continued to play after he was struck, but the pain worsened and he was shut down after an X-ray revealed the fracture. He was hitting .297/.323/.472 at the time of the injury with six home runs, 10 stolen bases, 31 RBIs and 48 runs scored in 68 games. Anderson's glove is a much bigger question mark than his bat. He's committed a whopping 31 errors this season. Still, the Sox have given no indication they plan to move him off shortstop.

4. Tyler Danish, RHP, Winston Salem -- The second-round pick in the 2013 draft started the year in Kannapolis and overmatched opposing hitters, going 3-0 with 0.71 ERA in seven starts. He was elevated to Winston-Salem, which is an aggressive placement for a 19-year-old kid. In seven starts at High-A, he's 1-1 with a 5.16 ERA, but at least he's got 26 strikeouts in 29.2 IP over seven starts. He recently returned from a short stint on the disabled list, and his three-quarters arm slot (think Jake Peavy) has some scouts concerned about his durability. But, Danish has a 95 mph heater with good sink, and the Sox like pitchers with good sinkers. Danish is a longer-term prospect. You won't be seeing him in Chicago this year or next year. Maybe 2016 if all goes well.

5. Courtney Hawkins, OF, Winston-Salem -- I heard a report today that Hawkins might be headed to the seven-day DL after crashing into a wall in left field on Wednesday night. I haven't heard anything about the extent of the injury, but hopefully it is not serious. The 2012 first-round pick dropped on some of the prospect lists after a wretched 2013 that saw him hit .178/.249/.384 in High-A. Again, though, that was an aggressive placement by the Sox. Hawkins was a 19-year-old playing against older guys last summer. This year, he's repeating the same level and has improved. He's hitting .255/.337/.482 with 13 home runs and 59 RBIs in 79 games. That's a good RBI total. He had only 62 in all of 2013. I think 2015 will be the big year for Hawkins. He'll probably be moved up to Double-A, and we'll see if he can keep his career on an upward arc.

Doubleheader loss highlights White Sox' pitching holes, questionable management

From 2009 to 2012, there were many times I heard White Sox fans wish for the front office to "blow up" the team's veteran core and start a rebuilding process. My response to those comments was often along the lines of "Be careful what you wish for."

Rebuilding is a hard and oftentimes frustrating process, and Sox fans are learning that this season. It's difficult, because even in a year where you know your team is not going to make the playoffs, you'd like to at least have hope that your team can win the next game on its schedule. But during a rebuilding year, that hope is not always present. There are certain days where you just know your team has little or no chance at victory.

For me, Tuesday was one of those days. The White Sox were scheduled to take on the Los Angeles Angels of Anaheim in a doubleheader at U.S. Cellular Field. Normally, a fan gets excited about 18 innings of baseball in a day, but one look at the pitching matchups for this twinbill was enough to make a Sox fan hold his head in despair.

The Angels, who currently lead the wild card standings in the American League, were throwing their top two pitchers -- Garrett Richards and Jered Weaver. The Sox were countering with their No. 4 and No. 5 starters, two guys who are lucky to be in the big leagues in Hector Noesi and Scott Carroll.

It was impossible to escape the nagging feeling that the Sox were destined to absorb a pounding in this doubleheader. And, indeed, both Noesi and Carroll pitched poorly. The Angels swept the twinbill by 8-4 and 7-5 scores.

Noesi was handed a 3-0 lead in the first inning after Jose Abreu connected for his 26th home run of the season, but he couldn't hold it. In fact, Noesi embarrassed himself and the team by walking seven men in 5-plus innings. He allowed five earned runs. Meanwhile, Richards settled in and gave his team eight quality innings, and the Sox never had much of a prayer -- despite the promising start.

The good news for the Sox was they only had to use two relief pitchers -- Ronald Belisario and Daniel Webb -- to eat up the last four innings of the game. Given the circumstances, it could have been worse, and the Sox' bullpen was still in relatively good shape going into the nightcap.

As expected, Carroll struggled in Game 2. He gave up three runs in the second inning to put the Sox in an early hole, and by the sixth inning, the Angels were out to a seemingly comfortable 6-2 lead. However, the Sox fought back with three runs in the bottom half of that inning. Dayan Viciedo's two-run homer cut the deficit to 6-5. The Sox had the potential tying run on third base and the potential go-ahead run on first before the Angels escaped the inning.

Weaver had entered Tuesday's contest with an 8-2 record and a lifetime 1.70 ERA against Chicago. On this day, the Sox touched him up for five runs over 5.2 innings. That's good offensive production against a quality, top-of-the-rotation pitcher.

Going into the seventh inning, the Sox trailed by just one run, and I figured they would take Carroll out of the game. None of their three best relievers -- Jake Petricka, Javy Guerra or Zach Putnam -- had pitched in Game 1. All were rested and ready.

Alas, Carroll was inexplicably allowed to start the seventh inning. No, his pitch count wasn't high. He hadn't reached 80 pitches yet. But, he hadn't been effective, and the top of the Los Angeles batting order was due up.

Naturally, Carroll walked Kole Calhoun and Mike Trout back-to-back to start the inning. Finally, Petricka was summoned from the bullpen. He allowed one inherited runner to score before extricating the Sox from a bases-loaded mess, and the damage was done. The Angels had scored an insurance run, and the good vibes from the three-run rally the Sox had the previous inning were snuffed. Los Angeles had little difficulty closing out the win from there.

You see, it's hard enough to win when you only have three legitimate major league starting pitchers on your roster. The Sox came into Tuesday on a three-game winning streak, because Chris Sale, Jose Quintana and John Danks had all won their most recent starts against the Toronto Blue Jays over the weekend.

But when Noesi, or Carroll, or Andre Rienzo take the mound, this team is asking way too much of its offense. You can't expect to be consistently competitive when you send bums like these to the mound.

The problem is made even worse when the manager and the pitching coach continually push their luck, trying to coax one more inning out of a struggling starting pitcher who hasn't earned the right to be out there. Would the Sox have won Game 2 had Carroll been pulled after six innings? Probably not, but it doesn't take a genius to see they would have had a better chance had Petricka been allowed to start his own inning in the seventh.

That's what being a manager is all about -- giving your team the best chance to win. Robin Ventura and Don Cooper should have been happy Carroll got through six innings, given the subpar stuff he was featuring. Instead, they got greedy and asked him to try to get through seven. It wasn't happening, and as a fan, bad management only adds to the frustration of having to watch a pitching staff full of gaping holes.

Jake Peavy's struggles continue in Boston

The White Sox, Boston Red Sox and Detroit Tigers made a major trade on July 30 of last year: Pitcher Jake Peavy went from Chicago to Boston; shortstop Jose Iglesias went from Boston to Detroit; and outfielder Avisail Garcia went from Detroit to Chicago.

It's been mentioned more than once that Peavy is the only one of the three major players in that deal to be healthy this season. Iglesias has missed the entire year with stress fractures in both of his legs, while Garcia suffered a torn labrum in his left shoulder the second week of the season and is done for the year. Meanwhile, Peavy, who has spent time on the disabled list in five of the past six seasons, has made all 17 of his starts for Boston.

That said, it hasn't been a good year for the former NL Cy Young award winner. Peavy is just 1-7 with a 4.82 ERA in those 17 starts. He is winless in his last 12 starts after losing, 2-0, to the Cubs on Monday night. Peavy actually pitched well in his latest outing, allowing just a two-run homer to Chicago outfielder Nate Schierholtz over six innings. He was simply outpitched by Cubs right-hander Jake Arrieta, who no-hit the Red Sox for the first 7.2 innings.

Respectable outing against the Cubs aside, the long-term trend for Peavy is not good. His 4.82 ERA would be the second-worst mark he has had in his career. His only worse year (4.92 in 2011) was his first year back from major surgery with the White Sox.

Peavy's WHIP (1.443), FIP (4.86) and strikeout rate (7.0 for 9 IP) all represent career worsts. He will be a free agent at the end of the season, and there are rumors he'll be on the move again at this year's trading deadline. The emergence of Rubby De La Rosa might put Peavy's rotation spot in Boston in jeopardy, if the Red Sox can manage to keep Clay Buchholz healthy.

There's no doubt White Sox fans are filled with despair when they see the likes of Hector Noesi and Scott Carroll making starts every fifth day, but know this: The Sox traded Peavy at the right time. If he were still in Chicago, he probably wouldn't be helping matters much.

It stinks that Garcia is down for the year, but he's only 23 and will likely bounce back from the injury. At this point in time, any team would rather have Garcia than Peavy. Even if the Red Sox are shopping Peavy this July, I'm not convinced any contending team will be eager to acquire him.

Even if Garcia struggles coming back from his injury, Chicago still might get something good from that trade. The South Siders got pitcher Francellis Montas from Boston in that three-team deal. Montas was recently selected to pitch in the MLB Futures Game, although he is now sidelined with a minor knee injury and will not be able to perform.

Peavy seems to be on the downside of his career. He may not be injured now, but he's pitching like a guy with a lot of wear and tear. He's not missed in Chicago. If you're a Sox fan, the players Chicago received in that deal are more likely to contribute to a contending team in the future than Peavy.

White Sox designate Scott Downs for assignment; Eric Surkamp called up

The White Sox on Thursday designated left-handed relief pitcher Scott Downs for assignment.

Downs, 38, was 0-2 with a 6.08 ERA in 38 appearances this season. Downs was working on a one-year, $4 million contract, with an option for 2015. The Sox will eat about $2 million as a result of this decision, but this is the right move to make -- especially since the $4.25 million option for next year would have vested had Downs reached 55 appearances.

Apparently, the walk Downs issued to Chris Davis in the middle of Wednesday night's eighth-inning meltdown was the final straw in what has been a string of poor performances by the washed-up lefty.

Whenever a player gets designated, it's never about one single game. Downs has been bad all season, and the Sox letting him go only reinforces the point I made after last night's loss -- why do managers feel the need to bring a left-hander into the game just because a left-handed hitter is at the plate? In particular, why bring a left-hander who has pitched so poorly that he's on the verge of release into a high-leverage situation? How is that fair to the team?

No one should be surprised that Downs failed. He's failed all year, and now he can go fail somewhere else. 

Left-hander Eric Surkamp has been called up to take Downs' place on the 25-man roster. Surkamp, 26, was picked up on waivers from the San Francisco Giants in December. He was once a top prospect in the San Francisco system, before Tommy John surgery stalled his career.

In 14 games (11 starts) at Triple-A Charlotte this season, Surkamp is 3-4 with a 4.54 ERA. Those numbers might not impress, but he's been trending the right way recently. He was named the Triple-A International League Pitcher of the Week for June 16-22. He owns a 2.63 ERA over his last four starts, with 31 Ks in 24 IP.

Surkamp has posted some good peripheral numbers in the minors. He has struck out more than one batter per inning -- 84 Ks in 73.1 IP. He has walked only 17 and given up just eight home runs -- about one every nine innings -- this year. He's been throwing strikes, missing some bats and generally keeping the ball in the park. We'll see if he can make these numbers translate to the big-league level.

The left-hander has a plus curveball, which is the reason for the high strikeout total. His fastball sits in the high 80s, so he's not going to overpower anybody with that pitch. The key for Surkamp will be locating his fastball well enough to keep big-league hitters from hurting him. Then, if he's ahead in the count, he can use his breaking ball as an out pitch.

The standard isn't real high here. All he has to do is be better than Downs, and in a rebuilding season, the Sox have nothing to lose by seeing what Surkamp has to offer. 

Robin Ventura's strict adherence to lefty-righty matchups costs White Sox in Baltimore

Anyone who has ever watched a game with me knows my biggest pet peeve in baseball is walks. I hate pitchers who walk people. I hate giving hitters a free 90 feet. Just throw the damn ball over the plate, will you?

But, a close second on that list of pet peeves is the way modern-day managers adhere strictly to lefty-righty matchups at all times. Robin Ventura's belief in lefty-righty matchups played a significant role in the White Sox' 5-4 extra-inning loss to the Baltimore Orioles on Wednesday night. Ventura is hardly the only manager in baseball guilty of this sin -- all of them do it these days -- but the bottom of the eighth inning of Wednesday's game is a good case study in why this lefty-righty stuff drives me absolutely bananas.

The Sox were leading 4-0 going into the fateful eighth inning. Starting pitcher Hector Noesi had been sailing along until that point, but he gave up back-to-back singles to start the frame. With runners on first and second, the middle of the lineup was due for Baltimore. Ventura likely didn't want Noesi to face Steve Pearce, Adam Jones or Chris Davis for a fourth time, so he correctly went to the bullpen and brought in reliever Zach Putnam.

Putnam did a fine job. He retired Pearce and Jones on fly balls to center field, and his stuff looked good. The runners were still planted at first and second with two outs, and Putnam looked poised to work out of the jam and keep the Sox ahead by four runs.

Alas, Davis is a left-handed hitter, and by golly, we can't leave the right-handed Putnam in to face a left-handed hitter, can we? No. That would be dangerous. So, Ventura summoned his washed-up lefty reliever, Scott Downs, who by the way failed to retire Davis when he faced him on Tuesday night.

The Sox are lucky Downs didn't give up a three-run homer to Davis during the course of the at-bat. He hung Davis two breaking balls. Fortunately enough, Davis fouled off both of them. Eventually, Downs walked Davis to load the bases (did I mention I hate walks?), which brought Nelson Cruz to the plate.

Cruz, a strong right-handed hitter, ranks second in the American League in home runs. You can't leave Downs in to face him, so Ventura had no choice but to go to the bullpen once more. He summoned Javy Guerra, which is probably as good a call as he could have made under the circumstances, but I trust Putnam more than Guerra. It would have been nice to have Putnam on the mound in that high-leverage spot, but he had already been relieved of his duties.

Guerra fell behind in the count and eventually served up a game-tying grand slam to Cruz. Baltimore went on to win the game in 12 innings.

I firmly believe that if Putnam had been allowed to face Davis, he would have retired him, and the Sox would have taken a four-run lead into the ninth. More than likely, the outcome of the game would have been different.

Why do managers insist on removing an effective right-handed pitcher from the game just because a left-handed hitter is at the plate? Why do managers feel they need to burn through three or four relievers in the seventh or eighth inning? To me, if you bring in enough relievers, eventually you are going to stumble on a guy who doesn't have his stuff.

Putnam had his stuff. What excuse is there for not sticking with him? There is none.
