Defensive miscues cost the Colorado Rockies dearly in a pitchers duel in Los Angeles last night. Ty Wigginton dropped a fly ball that sparked a three-run fourth inning, giving the Dodgers all the offense they would need in a 3-2 victory over the Rockies. The third and eventually decisive run scored when a sliding Ryan Spilborghs tripped second baseman Mark Ellis from behind on a short fly ball, allowing Matt Kemp to score after the ball was caught. Todd Helton had both RBI for the Rockies in the losing cause. Jhoulys Chacin gave up all three Dodger runs in his six innings to take the loss, though only one run was earned. The final game of the Rockies three game series in LA is set for tonight. ESPN Radio 1410 has the action, with pregame coverage starting at 8:30 and the first pitch at 9:10.
