The Colorado Rockies place Aaron Cook on the DL
The Rockies have placed righty starter Aaron Cook on the 15-day disabled list with a strained rib-cage muscle. This will hurt the Rockies as Cook has been one of their best starters this season. He has started 25 games this season for the Rockies and he is 8-7 with a 4.12 ERA and a 1.34 WHIP. He will be replaced in the rotation by Elmer Dessens.
