Breaking down Peavy's success

Jake Peavy's repeated it over and over. He's healthy, and he's ready to finally be the pitcher the Sox thought they were getting at the trade deadline in 2009.

But any skepticism regarding the 31-year-old coming into the season was warranted. He hasn't thrown more than 112 innings since coming to the White Sox, and he hasn't made 30 starts since he won the NL Cy Young in 2007. Along the way, he's shown flashes of his old self, but those have quickly been drowned out by injuries or ineffectiveness.

It'd be easy to simply say Peavy's first five start of 2012 are a return to his pre-2008 form. They're not. They're the beginning of the post-2011 Peavy.

Five years ago, Peavy was a blow-it-by-you pitcher with electric stuff. He averaged over nine strikeouts per nine innings from 2004-2007, featuring a fastball with an average velocity that crept into the mid-90's.

But a spate of injuries took some life off Peavy's fastball. His average velocity on that pitch dipped to 90.7 mph in 2011, which was the first year in which Peavy started to make a change in the way he pitched.

With his days of averaging a strikeout per inning gone, Peavy became extremely stingy with walks. He averaged just 1.93 walks per nine innings last season, a career best. Unfortunately, Peavy struggled with command, and a dead arm period didn't help. His ERA after 111 23 innings last year was 4.92.

But so far in 2012, it looks like Peavy has figured out how to be a different pitcher. His strikeout rate has remained consistent (7.66 K9 to 7.88 K9) while his walk rate has dipped a bit (1.93 BB9, 1.19 BB9) and he's doing an outstanding job of keeping the ball in the ballpark.

That Peavy's only allowed seven runs all year is a pretty good indicator that he's keeping the opposition off-balance, utilizing his repertoire to its fullest. Interestingly enough, Peavy's pitch selection isn't too far off from what he did in 2007, per FanGraphs:

YearFBSLCTCBCH200757.423.29.32.57.4201254.520.411.45.08.7
But Peavy's been hitting his spots and mixing these pitches better than he has since he joined the White Sox. His stuff isn't as good as it was five years ago, but he's adapted to it and, despite the same arsenal of offerings, become a different pitcher.

On the flip side...

Not everything is looking up for Peavy, though. He hasn't kept the ball on the ground, as 57 percent of the balls he's allowed to be put into play have been in the air. Only about 2 percent of those fly balls have gone for home runs, which isn't sustainable. If Peavy keeps allowing so many fly balls, eventually his luck will turn and more of them will go over the fence.

The good news is that Peavy's allowed one ground ball for every fly ball over the course of his career, so his high fly ball rate through five starts probably won't persist. But eventually, he will have to do something different, less he risk giving up quite a few home runs as the season goes on.

That's really the only real point of concern regarding Peavy's performance going forward. He's not going to sustain a 1.67 ERA, but a mark in the low-3.00 range is hardly out of the question.

Of course, if he stays healthy. That's going to be the issue for Peavy all season. He's proven, so far, that he can pitch like an ace. But, unfortunately, his injury-riddled past four seasons mean there always will be concern about a trip to the disabled list.

If Peavy can stay off the shelf, though, he looks primed for a fantastic season.

White Sox Talk Podcast: Class A manager Justin Jirschele, youngest manager in professional baseball

27-year-old Justin Jirschele made quite an impression in his first season as manager of the White Sox Class-A affiliate in Kannapolis. He helped lead the Intimidators to the South Atlantic League championship, and was named White Sox Minor League Coach of the Year. Jirschele came on the podcast to speak with Chuck Garfien about how he went from playing minor league baseball with the White Sox to coaching in their system. He talks about how growing up with a dad who was coaching minor league baseball helped mold him as a manager who is wise beyond his years. Jirschele also gives a report on some of the top White Sox prospects he managed last season such as Jake Burger, Alec Hansen, Dane Dunning and Miker Adolfo.

After baseball punishes Braves, one ranker says White Sox have game's best farm system

The White Sox farm system is baseball's best, according to one of the people making those rankings.

In the wake of Major League Baseball's punishment of the Atlanta Braves for breaking rules regarding the signing of international players — which included the removal of 12 illegally signed prospects from the Braves' organization — MLB.com's Jim Callis tweeted out his updated top 10, and the White Sox are back in first place.

Now obviously there are circumstances that weakened the Braves' system, allowing the White Sox to look stronger by comparison. But this is still an impressive thing considering that three of the White Sox highest-rated prospects from the past year are now full-time big leaguers.

Yoan Moncada used to be baseball's No. 1 prospect, and pitchers Lucas Giolito and Reynaldo Lopez weren't too far behind. That trio helped bolster the highly ranked White Sox system. Without them, despite plenty of other highly touted prospects, common sense would say that the White Sox would slide down the rankings.

But the White Sox still being capable of having baseball's top-ranked system is a testament to the organizational depth Rick Hahn has built in such a short period of time.

While prospect rankings are sure to be refreshed throughout the offseason, here's how MLB Pipeline's rankings look right now in regards to the White Sox:

4. Eloy Jimenez
9. Michael Kopech
22. Luis Robert
39. Blake Rutherford
57. Dylan Cease
90. Alec Hansen
