|Rest easy, Aramis, and remember: lift with your legs, not your thumb.|
I also don't know why so many people are complaining that this move wasn't made sooner. I'm sorry, but I don't think that a sore left thumb was a seriously significant contribution to Aramis's woeful pitch selection and decreased contact percentage. He just hasn't looked like a guy who can find the baseball with his bat or his eyes. Unless it's a blinding thumb soreness, I'd say the thumb and the bat have been two different issues.
Naturally, the Cubs are expected to call up Chad Tracy, who has been hitting 8.000 and slugging 1.600 x 10^17 at AAA Iowa. You can pretty much count on the team to be in first place by the end of the month.
UPDATE: It's official now. Aramis is on the 15-day DL, retroactive to June 8. I knew I could trust Snooki.
