Left-handed pitcher Jorge De La Rosa, who has been on the DL since April 4, retroactive to March 26, is still recovering from Tommy John surgery to repair the ulnar collateral ligament in his pitching arm, and Rockies manager Jim Tracy said the southpaw is scheduled to throw a bullpen session Wednesday.
Following Wednesday's bullpen session, De La Rosa is set to pitch for Triple-A Colorado Springs on Sunday in Fresno, according to Tracy. The lefty will be on a pitch count of "roughly about 75 pitches," Tracy said.
De La Rosa hasn't pitched in a game in the Majors in a year -- his last outing was May 24, 2011, against Arizona at Coors Field, when he tore his UCL -- and the lefty had a setback last week when he experienced tightness in his left forearm, causing the team to halt his rehab assignment.
While De La Rosa was throwing Wednesday, third baseman Chris Nelson was given a "rest and recovery day" for the Sky Sox as he continues to work his way back from a left wrist injury.
Nelson has started the last two games at third base for Colorado Springs, and went 3-for-4 with a double, an RBI and two runs scored for the Sky Sox on Tuesday. Tracy said Nelson will be used as a pinch-hitter for the Triple-A club Wednesday.
"It's more like a recovery day for him after two full days that have been played," Tracy said.
