The Orioles placed pitcher Jason Hammel on the 15-day disabled list Wednesday, retroactive to July 29, due to a right flexor mass strain. Hammel, who is expected to have an MRI Thursday, is feeling tightness in his forearm.
Hammel went 0-4 with a 5.52 ERA, 1.88 WHIP and 19:14 K:BB ratio in 29 1/3 innings over five July starts.
