Sixteen-game winner Jorge De La Rosa will miss Colorado's first-round playoff series against Philadelphia because of an injured left groin.
The left-hander left his last start Saturday night after hurting himself. He was scheduled to test his groin in a bullpen session Tuesday, but that was canceled.
"Our medical people had been working on him over the last couple days and his groin is about the same as it was when we had to remove him from the game Saturday night in Los Angeles," Rockies manager Jim Tracy said.
De La Rosa led the majors with 16 wins after June 1. He lost his first six decisions, and finished 16-9 with a 4.38 ERA.
