It appears Juan Morillo (RAK) needs surgery on his right elbow. He apparently returned to the US yesterday for additional testing.
Morillo initially injured his right elbow during an outing on 7/27 against the Softbank Hawks -- he threw only 8 pitches and was removed from the game. Since then, Morillo has been rehabbing at Ni-gun, but without much luck.
Morillo signed a 1-year contract that included an option for a second year. That second year might be in jeopardy depending on how things go with his elbow.
