Joe Kelly (hamstring) went two innings in his first minor league rehab start with Triple-A Memphis on Friday, allowing a pair of runs on two hits and three walks. Kelly struck out one on the night, throwing 21 of his 41 pitches for strikes. He'll make at least one other minor league rehab start before he's an option to rejoin the Cardinals rotation. He could be worth stashing for pitching-starved teams in deep mixed leagues.
