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.

Rick Hahn says 'there will be many' promotions for White Sox prospects this week

The White Sox have a number of highly-rated prospects performing well in the minors and some of them will be on the move within the system in a matter of days.

General manager Rick Hahn talked to reporters ahead of Monday night's White Sox game in Cleveland, a 6-2 loss, and gave the news. Well, sort of.

He didn't include names, but he did say that "there will be many" promotions after the minor league all-star games for Double-A and both Single-A teams take place on Tuesday.

Hahn added that Chris Getz, the White Sox player development director, will address the media before the White Sox host Oakland on Thursday about the moves.

If the all-star games are a reason to wait, it's safe to think some of the players involved will be playing in those games. So who could be on the move?

Double-A Birmingham has six all-stars: Eloy Jimenez, Zack Collins, Seby Zavala, Danny Mendick, Dane Dunning and Ian Hamilton. Jimenez is the name everyone wants to see on the move. He has torched the Southern League since getting off to a late start to the season due to injury. Hahn was asked about Jimenez, but didn't tip his hand as to whether he would be one of the promotions.

Dunning has been good in Double-A (2.78 ERA, 65 strikeouts in 58 1/3 innings), but was already promoted this season so he may not be on the move again.

Single-A Winston-Salem has five all-stars: Dylan Cease, Luis Alexander Basabe, Joel Booker, Bernardo Flores and Matt Foster. Cease, 22, could be due for a promotion with a 2.89 ERA and 82 strikeouts in 71 2/3 innings. There's also that outfield logjam the Dash, which won the first-half division title, have had all season.

Other than Basabe and Booker, Blake Rutherford and Alex Call are also noteworthy prospects being forced to split time in the Dash's outfield. If Jimenez is moving up to Triple-A, one or two names from this group could be on the move to take his spot in Birmingham.

This would especially make sense if highly-touted outfield prospect Luis Robert, who was supposed to be in Single-A Kannapolis for a short period before joining the Dash, is ready to move up as planned. Robert is hitting .289/.360/.400 in 13 games with the Intimidators.

Birmingham, Winston-Salem and Kannapolis were all off Monday. The various all-star games will take place Tuesday and the three teams will be off again Wednesday. The promotions could be announced Thursday ahead of Getz's scheduled media availability.

Zack Burdi is pitching off a mound again

Zack Burdi is pitching off a mound again

Zack Burdi was thought of as a college pitcher who could make the major leagues quickly after he was drafted in 2016.

The White Sox drafted him 26th overall that year and it appeared his quick rise through the minors was going to come true. Burdi reached Triple-A Charlotte by the end of 2016 and had a 2.25 ERA with 22 strikeouts in 16 innings with the Knights.

However, he had Tommy John surgery in July and hasn't pitched in more than 11 months. The 23-year-old from Downers Grove is nearing his return and had video proof.

That's Burdi throwing off a mound, which means a rehab stint might not be far behind. Burdi may not getting into the full swing of things before the minor league season ends in early September, but this is a good sign for him being ready to go for spring training in 2019.

Before going on the disabled list, Burdi had a 4.05 ERA with 51 strikeouts and 17 walks in 33 1/3 innings with the Knights in 2017.
