De La Rosa pitched in 10 games (all starts) for the Rockies this year and he was 5-2 with a 3.51 ERA and a 1.19 WHIP. Righty Greg Reynolds will take over for De La Rosa for the time being. Reynolds has pitched in 3 games (2 starts) for the Rockies so far this year and he is 0-0 with a 3.07 ERA and a 1.09 WHIP. Righty Aaron Cook will take over De La Rosa’s spot in the near future as he is currently on a rehab assignment.
