Contreras (forearm) allowed one run in two innings while pitching for Double-A Altoona on Wednesday. He gave up one hit, no walks and struck out three.
He threw 37 pitches (24 for strikes) in his first appearance since June 30. One of Pittsburgh's top pitching prospects, Contreras has registered a 2.44 ERA, 0.92 WHIP and 68:11 K:BB in 48 Double-A innings. Most importantly, it appears he's moved past the forearm injury that caused him to miss two months of development.
