DENVER (AP) - Jordan Pacheco hit a tiebreaking grand slam in the fifth and Carlos Gonzalez added a solo homer, helping the Colorado Rockies hold on for a 10-9 win over San Francisco on Friday night that snapped a 10-game skid against the Giants.
Pacheco laced his first homer of the season to left on a hanging slider from Madison Bumgarner (4-2), who failed to protect an early four-run lead.
Jorge De La Rosa (5-3) entered the game without giving up a run at Coors Field in 12 innings. He was hit hard, surrendering five runs in five innings, only to settle down enough to earn the win.
In the ninth, Rafael Betancourt struck out the side for his 10th save in as many chances.
