Before the Rockies lost Wednesday to the Giants, manager Jim Tracy said De La Rosa's next start would hinge on whether any Rockies affiliates are still involved in the playoffs.
De La Rosa pitched 3 2/3 innings in his last start Monday for Modesto against Bakersfield and is scheduled to next pitch Saturday. Modesto will play Lancaster for the Cal League title. The third game of the series is scheduled for Saturday at Lancaster.
De La Rosa underwent Tommy John surgery in June 2011 and twice had rehab assignments halted this season. He began his current rehab assignment Sept. 5 and threw three scoreless innings for Rookie-level Grand Junction.
Low Class A Asheville is the other Rockies affiliate still in the playoffs. The Tourists are playing Greensboro for the South Atlantic League championship. That best-of-five series is tied 1-1 and scheduled to conclude Saturday at Greensboro if it goes to a fifth game. The certainty of Modesto playing Saturday makes it highly likely De La Rosa will again pitch for the Nuts.
The Rockies and De La Rosa are hopeful he will be able to start for Colorado before the end of the regular season Oct. 3.
