Rockies activated RHP Roy Oswalt from the 15-day disabled list. Oswalt has been sidelined since early July due to a strained left hamstring. The veteran hurler was an abysmal 0-4 with a 7.64 ERA, 1.76 WHIP and 23/2 K/BB ratio over 17 2/3 innings before hitting the DL. He shouldn't be started in any mixed leagues down the stretch.
