High-A Greenville reinstated Valera (elbow) from its 60-day injured list Tuesday.
Valera has yet to return to action for Greenville since being activated, but he's apparently healthy again after he was recently able to face hitters in live batting practice. Before being shelved in late May due to right elbow soreness, Valera turned in a 5.40 ERA, 1.42 WHIP and 37:9 K:BB in 33.1 innings over eight starts for Greenville.
