Peavy to miss next start with elbow trouble

Jun 7 Peavy is likely to return to the rotation next week if he does not have any physical setbacks from a simulated game he threw on Saturday. Peavy, the reigning NL Cy Young winner, threw 61 pitches to three batters over four innings in a simulated game at Petco Park.
Advice: Peavy was placed on the 15-day disabled list with a strained right elbow on May 20, retroactive to May 15. He is expected to make his return against the Los Angeles Dodgers on Thursday afternoon as long he continues to feel fine. Peavy faced teammates Paul McAnulty, Luke Carlin and Craig Stansberry in the simulated game. Of his 61 pitches, 37 were strikes.

I'm still pretty optimistic he'll be back to normal for the rest of the year, but long-term I don't think he'll be an ace too far into his 30s.
