Checking in with former White Sox pitchers ... are any of them missed?

We know the White Sox had a respectable pitching staff in 2013, despite a miserable 63-99 record. The team numbers (3.98 ERA, 1.329 WHIP, 4.13 FIP), while not championship-caliber, were not terrible either.

We also know those numbers are down across the board here in 2014, even though the Sox (20-22) are still hanging around .500 going into this weekend's series against the Houston Astros. So far this season, Sox pitchers have posted a 4.74 ERA. The WHIP sits at 1.476, with a 4.44 FIP.

The Sox have dealt with a couple of key pitching injuries this year. Ace Chris Sale has been limited to four starts, and reliever Nate Jones has appeared in just two games. Both pitchers remain on the disabled list. Other pitchers have underperformed severely. Rookie Erik Johnson couldn't find the strike zone and earned himself a demotion back to Charlotte. Free-agent signee Felipe Paulino was a disaster in the rotation and eventually ended up on the disabled list.

In addition, several pieces of the 2013 pitching staff are no longer here for various reasons. Some were traded as salary dumps. Some were traded for young position players to get the rebuilding process started. Another left via free agency.

The Sox pitching staff is weaker this year because of a combination of factors, one of which is the fact that some guys who helped the team in the past are now elsewhere. But as I look at the list of pitchers who were here last year but are gone now, I can't say I miss any of them all that much.

Here's a closer look at those six pitchers and how they're doing now. All statistics are entering Friday's games:

Jake Peavy (Boston)

South Side departure: The veteran was traded last July in a three-team deal that netted the Sox right fielder Avisail Garcia.

Current numbers: 1-1, 3.94 ERA, 1.458 WHIP in eight starts

Is he missed?: People have noted Peavy is the only player still healthy who was involved in last July's deal. Garcia is on the DL for the Sox, and Tigers shortstop Jose Iglesias also is on the shelf. But, while Peavy's ERA is decent, I expect it to go up if he continues pitching the way he has. He's walked 27 men in 48 innings this year. His WHIP is well above his career norm of 1.184. The soon-to-be 33-year-old is on the back side of his career. I think the Sox traded him at the right time. Even with Garcia sidelined with a serious shoulder injury, he's far more likely to help the Sox over the next five or six years than an aging pitcher like Peavy.

Gavin Floyd (Atlanta)

South Side departure: An elbow injury limited the veteran to just five starts in 2013. He signed a free-agent deal with the Braves over the offseason.

Current numbers: 0-1, 2.70 ERA in two starts

Is he missed?: Floyd has made it back from Tommy John surgery and recently joined the Atlanta rotation. I've heard some people argue the Sox should have brought Floyd back on an incentive-laden deal, and that he would look good at the back of the rotation right now. That's probably true, but can you imagine what people would have said if the Sox had re-signed Floyd in December or January? The fans would have been howling about the team wasting resources on an injured player.

Hector Santiago (L.A. Angels)

South Side departure: The left-hander was traded over the offseason as part of a three-team deal that netted the Sox center fielder Adam Eaton.

Current numbers: 0-6, 5.09 ERA in eight appearances (seven starts)

Is he missed?: The Sox did a good job of selling high on Santiago, who made 23 starts and posted a respectable 3.56 ERA in 2013. But, Santiago is nothing more than a No. 4 or No. 5 starter, and he lacks the command to be a consistent pitcher. The Sox recognized he was unlikely to duplicate his success and flipped him for Eaton, who is the center fielder and leadoff hitter of the present and future. While there are injury concerns with Eaton, I don't think anyone would argue his upside is far greater than Santiago's. That's especially true since Santiago was recently removed from the Angels' rotation for ineffectiveness.

Addison Reed (Arizona)

South Side departure: The closer was dealt to the Diamonbacks straight up for third base prospect Matt Davidson.

Current numbers: 1-3, 5.03 ERA, 1.271 WHIP, 11 for 13 in save opportunities

Is he missed?:  As long as Davidson continues to struggle in Triple-A, people are going to continue to criticize the decision to trade Reed. That's especially true because Matt Lindstrom has been hit-or-miss as a closer for the Sox this season. However, it's fair to say Reed has had Arizona fans reaching for the antacid as well this year. Look at that high ERA and WHIP. It's not what you want from a closer. I like Reed, and I'm not going to try to convince anyone that he's not a decent bullpen guy. He is. However, he was never dominant and shouldn't have been considered an untouchable by any means. It is way too early to give up on the 22-year-old Davidson, and it's still way too early to judge that trade.

Matt Thornton (N.Y. Yankees)

South Side departure: His salary was dumped last July in a trade with Boston. The Sox acquired outfielder Brandon Jacobs from the Red Sox. Jacobs was later sent to the Diamondbacks as a throw-in as part of the Eaton/Santiago trade. Thornton signed with the Yankees over the offseason.

Current numbers: 0-1, 5.40 ERA, 16 games, 6.2 IP, 1.800 WHIP

Is he missed?: Thornton is nothing more than a situational left-hander these days. His K rate is about half of what it was during his White Sox heyday from 2008-2010. He's 37 years old. He's got a lot of mileage on his arm. By this time next year, he'll probably be out of baseball. He's had a nice career as a relief pitcher, but it's all but over now.

Jesse Crain (Houston)

South Side departure: He was traded (while on the disabled list) last July as part of a conditional deal with the Tampa Bay Rays. He never threw a pitch with Tampa Bay and signed with Houston as a free agent over the offseason.

Current numbers: None. He hasn't thrown a pitch since June 29, 2013, when he was still with the White Sox.

Is he missed?: Crain had an 0.74 ERA in 38 appearances at the time the Sox put him on the disabled list last year. He was always good when healthy, but you can't say you miss a guy who hasn't been on a big-league mound in nearly a year.

As a Sox fan, are there any of these guys you would take back if you could? Reed would help, but I think I'd rather have Davidson in the organization, all things considered. Even though the pitching is generally weaker this year, the Sox have made more good moves than bad over the past 12 months.

White Sox designate Jeff Keppinger for assignment

In a move that surprised many observers, the White Sox on Wednesday designated infielder Jeff Keppinger for assignment.

Keppinger, 34, hit a career-best .325 two years ago with the Tampa Bay Rays, but he slumped to a .253/.283/.317 slash line for the 2013 White Sox. He was limited by a right shoulder problem, which ultimately cut his season short and required surgery. He was slow to recover from the injury over the offseason and appeared in just six spring training games before being placed on the disabled list on March 30.

Keppinger has been on a rehab assignment since May 2 at Double-A Birmingham, where he hit .256 in 11 games. With the rehab period set to expire, the Sox decided they'd rather cut Keppinger loose than put him on the major league roster.

The decision is surprising because Keppinger is in just the second year of a three-year, $12 million deal he signed with the Sox prior to the start of the 2013 season. With the move, the Sox are opting to eat approximately $7.5 million dollars, which is a departure from business as usual on the South Side.

Typically in situations such as this, you would expect the Sox to trot Keppinger out to third base every day for the next two months, hoping he would play well enough to entice a contending team to take his salary off their hands.

Not this time. Instead, they recognized there is no place for Keppinger on the roster.

Conor Gillaspie has played well at third base for the Sox this season, and the team has hopes that prospect Matt Davidson will reverse his struggles at the plate and eventually become the long-term answer at the position. There's no room at second base for Keppinger, either, with younger players Gordon Beckham, Marcus Semien and Leury Garcia all ahead of him on the organization's depth chart.

Not to mention, the Sox recently promoted second baseman Micah Johnson, one of their better prospects, to Triple-A Charlotte. With Davidson and middle infield prospect Carlos Sanchez also toiling in Charlotte, there isn't even any room for Keppinger in the Triple-A infield. There is no point in giving Keppinger at-bats over any of these younger infielders, at any level, so it is the right baseball decision to send him packing.

In the past, the Sox have at times let economics get in the way of making the right baseball decision. In this case, I applaud GM Rick Hahn and the Sox front office for doing the right thing. At one point in time, signing Keppinger looked like a good move. It just didn't work out, but at least the Sox aren't compounding the mistake by keeping a useless player around because of money.

Keppinger is out of the organization, and the Sox rebuilding plan is better off for it.

Anthony Rizzo's interesting rebound season (so far)

Cubs first baseman and franchise cornerstone Anthony Rizzo is enjoying a resurgent season, and it's interesting how he's doing it.

Last year, Rizzo disappointed with a .233/.323/.419 batting line. Not what you want from your first baseman, even if it does come with a good defensive reputation. The two main culprits for the diminished output seemed to be at paltry .258 batting average on balls in play (BABIP), and an even more anemic .189/.282/.342 result against left-handers.

It always seemed like the BABIP would come back up a little since Rizzo has hit for good averages in the minors. While he isn't difficult to strike out, he also doesn't have severe issues making contact. And sure enough, Rizzo's BABIP is .299 to start the week, helping lift him to a .283/.399/.488 line so far this season.

The more interesting thing to me is that this year, Rizzo is batting .317/.408/.561 against left-handers, better than the .267/.394/.453 he's posting against right-handed pitchers -- basically the reverse of the results from the rest of his career. His BABIP is .357 against southpaws, while it's only .275 against righties.

Rizzo is only 153 plate appearances into the season, so instead of instructing us that he's figured out how to hit left-handers, the better assumption is that batting-average driven numbers are more likely to regress to something closer to what he's done in the past.

If Rizzo ultimately settles in with an overall BABIP around .290 this will still end up being a pretty solid comeback season for him, even if he doesn't finish it with an OPS around .900 that he's been dancing around most of the year so far.

To do that, he's going to have to keep up his power output, which faded on him when the weather got warmer last year, and show that his better contact against left-handers is for real.

Jordan Danks down because Moises Sierra might be a better hitter

There was probably some amount of rejoicing among White Sox fans when Jordan Danks and his .098/.229/.195 batting line were demoted to Triple-A Charlotte earlier this week.

The White Sox recently added Moises Sierra to their roster.

Danks has a glove that can carry him as a fifth outfielder on the roster of a good team. He's also made enough slow, steady progress through the minors offensively that he's earned an extended big-league look under the right circumstances. Those circumstances include a wave of injuries to the Sox outfield, and frankly a lack of better options.

Two things mucked up Danks' big opportunity. First there was his awful showing at the plate, which would have been too much to stomach even if the Sox were 10 games or so under .500 and more squarely in "playing for next year" mode. The second thing is the pickup of Moises Sierra off waivers from the Blue Jays.

Sierra didn't end up on waivers because he's much of a prospect. He ended up there because he spent his time in Toronto this year making Danks look like Mike Trout with his .059/.086/.059 "hitting" performance. And Sierra can't play center field.

In Danks and Sierra we're still talking about two guys who have combined for 629 sporadic big-league at-bats, so we should probably look at what they've done in the minors to get a better idea of who might hit better.

Player	PA	BA	OBP	SLG	K%
Danks	2,079	.266	.353	.423	27
Sierra	2,859	.266	.329	.408	20

Their overall work makes Danks look like a better player, but that's not really fair to Sierra, who began playing ball as a 17-year-old free agent out of the Dominican Republic. Danks was drafted out of college and began as 21-year-old.

So here's what they've done in Triple-A:

Player	PA	BA	OBP	SLG	K%
Danks	1,566	.265	.350	.422	28
Sierra	834	.275	.343	.447	23

Now three things jump out at you. The first is that Danks has played A LOT more games at Triple-A than Sierra. Which makes sense because Danks is 27 years old and has seen his career stalled. The second is that Danks has a lot of problems making contact with his low average and high strikeouts despite spending four seasons in Charlotte. The third thing is that Sierra has more power. Power that's developed as he's gotten older, and might develop even more as he's only 25 years old.

Speaking strictly about offensive potential, to me it looks like Sierra has more of it.

Everything else isn't equal, though. Danks might be the better overall player. In fact, because Danks' glove gives him a higher floor as a player, I'd bet on him being the more likely of the two to be with the Sox two years from now. Not as a starter, but as that fifth outfielder.

At the same time, Adam Eaton will be back, and the job in center is his. With Avisail Garcia out for the season, the Sox have more time to devote to player development. Particularly in the corner outfield spots, where Danks' glove has less value and where teams want more offense. And while nobody loves Alejandro De Aza's defense, he's good enough to be the primary backup in center, where Leury Garcia can also presumably play. These are probably the best back-of-the-roster choices the Sox can make with Paul Konerko taking up a mostly ceremonial spot.

Sending Sierra away means throwing him back on the waiver wire, which the Sox are understandably reluctant to do given their organizational lack of depth in the outfield. So for now Sierra gets his turn to audition, and Danks will go back to Charlotte where he'll probably have to hit better than Sierra does in Chicago to merit a callback without a trade or another injury opening that door for him.

Unless something better comes along than either Sierra or Danks.

It's time for the Cubs to get rid of Darwin Barney

Outside of shortstop Starlin Castro and first baseman Anthony Rizzo, the Cubs have gone with a musical chairs approach to their infield. Between second and third base they've rotated Luis Valbuena (20 starts), Emilio Bonifacio (12), Mike Olt (16) and Darwin Barney (16).

Bonifacio has also gotten time in the outfield, but this is a pretty even job-sharing arrangement. That makes some sense in that the Cubs have a lot of guys they're trying to sort out, even if not for their direct benefit, then to give scouts from other teams a look-see at players so they can be peddled for something interesting in a trade.

Olt is a former top prospect not far from the form that made him one, so getting his career back on track would be huge. Valbuena and Bonifacio are playing like credible stopgaps or bench options should a better team come calling for one of them. Maybe the Cubs will like Bonifacio enough to hammer out an affordable contract extension.

Barney is hitting like one of the worst hitters in all of baseball. Which he is outside of pitchers and backup catchers. That's not just his meager 63 plate appearances this year (.127/.226/.181, so emphasis on meager). That's been his career in the majors (.242/.241/.331). That's really what his body of work in the minors would have suggested (.288/.337/.378).

There's his glove, which is excellent at second base and would probably play well at short or third. But as good as it is, it won't carry him as a starter at any position, and you'd really rather he never have to hit, making him a second-best utility infield option on a decent bench. That means he's not likely to bring the Cubs back much value in trade.

After making $2.3 million this season, I think it's also safe to say that if he's not sent to another team, the Cubs won't be tendering him a contract and taking him to arbitration for next season.

Barney simply has no value to the Cubs right now, and keeping him around is eating into something the team has right now that's very valuable, and that's playing time for those other guys who might play their way into the long-term picture, or at least boost their short-term value.

Even as a "rebuilding" team, the Cubs have other, better options. They should go with them.

Paul Konerko gets a parting gift, then gives a parting shot

We don't often say nice things about North Siders on this blog, but give the Cubs credit for a classy gesture before Tuesday night's crosstown game at Wrigley Field.

White Sox captain Paul Konerko, playing his last game on the North Side, was presented with a green No. 14 placard from the Wrigley Field scoreboard by Cubs pitcher Jeff Samardzija. Fans from both teams applauded, and it was nice moment recognizing Konerko's long and successful career with the Sox.

I'll bet the Cubs are glad Konerko is finally retiring at the end of the season. The veteran first baseman has tormented the Cubs with big hit after big hit for years. In 75 career games against the Cubs, Konerko has posted a .300/.361/.592 slash line with 20 home runs and 59 RBIs. That's a pretty good track record.

On Wednesday night, the crosstown series shifted to U.S. Cellular Field, and Konerko received what will probably be his last starting nod in a game against the Cubs. He responded with two doubles, including perhaps the biggest hit of the night in the White Sox's 8-3 victory.

With the Sox leading 4-3 in the fifth inning, Konerko stepped to the plate with the bases loaded and ripped a three-run double into the left-field corner off Cubs starter Travis Wood. Later in the inning, Konerko scored on an RBI single by Marcus Semien to cap a four-run rally, and the Sox coasted from there to their fourth straight win overall and third consecutive win over the Cubs.

For what it's worth, the Sox have clinched the 2014 Crosstown Cup with this victory. The fourth and final game of the series will be Thursday night at the Cell. The Cubs will be starting a right-handed pitcher, Jake Arrieta, so that means Konerko probably will not be in the starting lineup.

No matter. He delivered his parting shot to the Sox's crosstown rival with that laser-beam double on Wednesday night. It was a fitting end to a career spent beating up on Cubs pitching.

When Conor Gillaspie returns from the DL, who will the White Sox send down?

White Sox third baseman Conor Gillaspie is on a rehab assignment at Triple-A Charlotte and could come off the disabled list as soon as Wednesday.

Before suffering a bruised hand, Gillaspie was hitting .302 with 12 RBIs in 16 games. Upon his return, he's going to take over for Marcus Semien as the Sox's regular third baseman. And unlike earlier in the year, there isn't much playing time available for Semien at second base, now that Gordon Beckham is back off the disabled list.

So, what do the Sox do with Semien? Is he the guy they send back to the minors when Gillaspie is activated? Or will outfielder Jordan Danks or all-purpose player Leury Garcia be optioned? It's not an easy call, and there is more than likely some internal debate going on among White Sox brass.

If the fans had their way, Beckham would probably be the guy shown the door -- even with his 4-for-5 performance and go-ahead home run in Tuesday's 5-1 victory over the Cubs at Wrigley Field. The disappointing second baseman has become a bit of a whipping boy for fans on Internet message boards, but let's be realistic: The Sox aren't going to cut Beckham loose now or look to trade him when he's just coming off an injury and his value is at its lowest.

For better or for worse, Beckham is the regular second baseman until at least July. Defensively, he's still the Sox's best option at the position. If he rebuilds his value by midseason, he could be shipped off at the trade deadline to clear a starting spot for either Semien or Micah Johnson. But that's a question for another time.

When Gillaspie returns, one of Semien, Danks or Garcia is going to be gone. Of the three, Danks is perhaps the weakest player, but he needs to remain on the roster for as long as Adam Eaton is on the disabled list. With Eaton on the shelf, Danks is the only good defensive outfielder the Sox have. Without him, you're looking at a starting outfield of Moises Sierra, Alejandro De Aza and Dayan Viciedo -- with Garcia, an infielder by trade, and Adam Dunn, a designated hitter by trade, filling backup roles. Not acceptable. If I'm making the decision, Danks stays despite his ugly .098/.229/.195 slash line.

That leaves Semien and Garcia. A lot of Sox fans would disagree with me here, but I think Semien goes to Charlotte for more playing time. Garcia stays as the backup infielder.

It's tough because Semien has shown a flair for the dramatic this season. He's had some big hits for the Sox -- 15 of his 16 RBIs have come in the sixth inning or later. That said, I can't ignore his.213/.267/.346 slash line, nor can I ignore his league-leading 45 strikeouts.

I like Semien and think he could be an everyday player in the majors at some point in the future. I just don't think that day is today. I don't think he would benefit much from sitting on the major league bench, so I support sending him to Triple-A and having him work on closing some of the holes in that swing. Garcia, to me, will never be more than a utility infielder anyway, so I'm fine with leaving him right where he is.

For me, Semien's development is a greater priority than Garcia's development. He's the better of the two players. Semien's the one who needs the everyday at-bats in my book, so the Sox should put him in a place where he can get them. That place, right now, is Charlotte.

We'll probably find out sometime in the next 48 hours whether the Sox agree with me.
