LOS ANGELES -- Rockies left-hander Jorge De La Rosa was removed after one inning of his injury rehab start Saturday night at Double-A Tulsa as a precaution because of forearm tightness, the Tulsa World newspaper reported via Twitter on Saturday night. De La Rosa, returning from Tommy John surgery on his left elbow last year, had made two starts at Class A Modesto. On Saturday against Arkansas, he gave up five hits and four runs while throwing 28 first-inning pitches, then was seen talking with a trainer. He did not go out for the second inning. It is not clear if this will lengthen the injury rehab assignment. Pitchers have a 30-day window, but any new injury could allow the team to restart the window. When manager Jim Tracy announced the beginning of De La Rosa's rehab assignment, he emphasized that there would be no time clock and De La Rosa will be activated only when ready.
De La Rosa, 31, was the Rockies' best pitcher last year (5-2, 3.51 ERA in 10 starts) when he suffered the torn elbow ligament in May during a start at home against the D-backs. De La Rosa is at the back end of a two-year, $21.5 million contract that also has a player option for 2013 that is worth $11 million.
