The Oklahoma announcer just referred to Guzman "leaving with some sort of arm injury." Doesn't sound like we can get the Iowa broadcast today. As craig mentioned, Guzman was having a stellar game before the injury: 3.2 IP, 0 R, 2 H, 8 Ks, 0 BBs, HBP, 66 pitches, 44 strikes. EDIT: Apparently Jon edited what I just said in into his previous post.
