The Colorado Rockies were once again their own worst enemy yesterday, as unearned runs proved to be the difference in a 4-2 loss to the San Francisco Giants at Coors Field. The Rockies were trailing 2-0 into the sixth inning when center fielder Dexter Fowler dropped a routine fly-ball to start the frame. Two runs would come into score after two outs were recorded in the inning, meaning neither run was charged as earned to Rockies starting pitcher Jamie Moyer. At the plate, the Rockies were no-hit for five and a third innings by Giants hurler Madison Bumgarner, but nearly rallied in the ninth, scoring a run and loading the bases before the final out was made. The Rockies begin a three-game series at home against Arizona tonight. ESPN Radio 1410 has the action, with pregame coverage at 7:05 and the first pitch at 7:40.
