Almost gagged when I read this on allbaseball.com:
* Corey Patterson won’t be 27 until the middle of August, and his poor 2005 showing was largely due to bad luck, specifically an unusually low batting average on balls-in-play. He hit only .262 when he didn’t homer or whiff last year, compared to the previous three seasons in which he hit well over .300 in those situations. (The league average is usually around .290, with speedy guys like Patterson typically a little higher.) That and his age should help Patterson gain about 40 points of batting average and return to being a useful regular, maybe better.
Bad luck? Patterson has over 2000 major league ABs. He's a career 252/293/414 hitter. I won't say impossible, but it certainly is unlikely he will fulfill his potential and be a star.
