Podsednik out (for 6 weeks), Erstad in

MLB.com is reporting that White Sox left fielder Scott Podsednik will be out for six weeks after groin surgery Tuesday, and that the team is also close to a deal with outfielder Darin Erstad.

Right off the bat, it looks like the Sox are looking for Erstad to compete with Brian Anderson in center field and possibly help Ryan Sweeney cover left field in case Podsednik suffers a setback.

Erstad has hardly been the picture of health. When he hasn’t missed considerable time as he has in three of the past four seasons, he’s battled injuries of the nagging variety that compromise his ability to be a useful player.

Since the Sox are only counting on him to be a de facto fourth outfielder, that’s not a big deal. But there’s one glaring problem: Erstad can’t really hit lefties.

Here’s a look at some of the recent work Sox outfielders have done against southpaws:

Player	OPS	OPS vs. LHP
Podsednik	683	562
Anderson	649	638
Sweeney*	804*	665*
Erstad**	697**	614**
Ozuna	809	827

*=2006 at Charlotte
*=2005

I put Erstad’s 2005 season in the table because he had fewer than 100 at-bats in 2006. You can argue that even a full season is too small of a sample size to mean anything, but these numbers are not out of line with what all of these guys have done in their careers, excepting maybe Sweeney:

Player	Career OPS	Career OPS vs. LHP
Podsednik	720	675
Anderson	642	603
Sweeney	N/A	N/A
Erstad	771	722
Ozuna	703	734

As Erstad and Podsednik have aged, their splits have become more pronounced. Anderson and Sweeney may yet come around to hit lefties better as they both approach their peaks. It appears the Sox are counting on it since only Ozuna can hit lefties. And you can hardly describe him as an “outfielder.”

Even if everyone continues to hit this poorly against lefties, it wouldn’t be a disaster, especially when you consider exceptional left-handed pitching in the American League Central is dragging some of these numbers down. Only Podsednik’s splits are very drastic. While the groin surgery might help him get back on track in the stolen base department, I doubt it will help him at the plate against southpaws, against whom he looked lost through all of 2006.

And that’s the rub. Podsednik is slated to be the starting left fielder. If the Sox were going to bring in an outfielder, ideally it would be a lefty-killer to take away those at-bats from Podsednik.

Erstad, who was once the elite defensive center fielder in the AL, gives the Sox the luxury of letting him take all the at-bats from Anderson should he bomb at the plate again this year. But he doesn’t have the offensive skills to either platoon with Podsednik, or to take over left field outright.

So the long story made short is that this is an OK signing, but not a great one. It gives the Sox some more depth, but doesn’t really solve the offensive problems in either left or center field.
