Brent Lillibridge sought to destroy this notion last season, but was eventually brought back into cold grip of reality.  But now A.J. Pierzynski is the one flouting logic by having the best season of his life at 35…by becoming an entirely different hitter.

If you’re unfamiliar with Pierzynski’s approach of the last few years–he never walked, he never struck out, and he rarely did things besides single to right field.  He just matched his career-high in home runs from 2005 with 18, but even that year was an outlier from his career record.

This season, Pierzynski has walked in 5.8% of his plate appearances–small potatoes, but enough for the most walk-heavy season of his career.  He’s struck out in 14% of his plate appearances–perfectly normal, but more than double the rate he whiffed at last season.  And it’s hard to  overstate the increase in power production–Pierzynski has 18 HR when last year he had eight.  His isolated power is .236; if you added his ISO from the last two seasons together it’d be .237.

Thanks to Lillibridge, we’ve seen random power spikes before, and A.J.’s somewhat listless beginning to the 2nd half seem to indicate things were headed back to normal.  Then he complained of an oblique strain, missed a week, and returned to hit two  home runs out of Target Field in only two games he’s played since.  If you think it’s easy for lefties to yank balls out of Target Field, Joe Mauer has words for you.

Which points to the problem in predicting Pierzynski to level off.  He’s earning these home runs, they’re not wall-scrapers, or being aided by lucky gusts of wind.  Only four of his 18 home runs could be said to have benefitted from the small confines of the ballpark he was playing in, and only one of those actually took place in U.S. Cellular Field.  He’s always had large raw power and strength when gets into one, and the 388 feet he’s averaging on home runs this season is one of his lower figures of the last six years.

A.J. could always crank it, but he generally didn’t, because his approach was all about making contact. and maybe he just isn’t normally this good at squaring balls up.  There’s nothing  in his plate discipline numbers to indicate he’s suddenly looking for pitches to drive, or even swinging harder, so it’s hard to make a conclusion much more definitive than “he’s in a groove.”

That’s not a satisfying explanation come contract time, but since it’s managed to carry over to the 2nd half and through an oblique strain, perhaps just enjoying the ride is an appropriate reaction.  We’re White Sox fans after all, worrying about sustainably doesn’t suit us.

In 86 at-bats during the 2012 season Lillibridge has amassed a .165/.212/.177 line so it’s not exactly an Infante/Sanchez type acquisition that instills fear in the Pale Hose faithful. As far as being fearful that Brent will rise to the challenge and show up his old team, Chicago and Cleveland exhausted most of their matchups early in the season, and only have one more series against the Indians left on the year. That will be the second to last series of the regular season, and it takes place at U.S. Cellular.

Good-bye again, Brent. We’ll always have 2011.

It is evident that the White Sox offense has slowed down significantly as of late. The Sox as a team have wasted some pretty stellar starting pitching over the last few weeks, dropping a few games in the standings. Lucky for us, the Indians lost today and the Sox were able to pull out the rubber match in extras.

The tenth inning started with a double by Alejandro De Aza (he was 2 for 5 today). After a Gordon Beckham flyout to center and a walk to Adam Dunn, pinch hitter Eduardo Escobar had a chance to be a hero. Escobar drilled a fastball to center field, plating the winning run in Alejandro De Aza from second.

Some other notable offensive performances from today:

De Aza- 2 for 5 (as previously mentioned) with the only run scored of the game

Beckham- also 2 for 5

Ok….. well thats really about it, not much offense today….

This was a big win for the White Sox as they had lost their last 4 series in a row coming into this 3 game set with the Brewers. With that win today the White Sox now own a half game lead in the AL Central division. Hopefully the momentum from today will board the teams charter to Minnesota with them.

The White Sox announced after the game that they acquired Kevin Youkilis from the Red Sox in exchange for Pitcher Zach Stewart and super utility man Brent Lillibridge. I think I speak for all Sox fans when I say, Brent, thank you for playing the game hard and for giving us all you had, good luck in Boston. I also think I speak for Sox fans when I say, Kevin, Welcome to the South Side, please give our 3B spot some offensive production.
