Giants starting pitcher Jonathan Sanchez pitched a marvelous game until the eighth inning, before allowing two hits and committing a throwing error, opening the door for the Colorado Rockies to come back and beat the Giants 5-3.

Sanchez appeared to be in cruise control through seven innings, allowing only a solo homer to Troy Tulowitzki, throwing only 81 pitches, and not allowing a walk. But the bottom of the eighth inning proved to be disastrous as Sanchez allowed back to back hits and throwing the ball away when Colorado pinch hitter Alfredo Amezaga sacrificed to the pitcher, allowing Ryan Spilborghs to score.

Giants reliever Javier Lopez fared no better as Dexter Fowler's double and Carlos Gonzalez's single scored the winning runs.

The Giants took an early lead on an RBI single by Miguel Tejada and a clutch two-out two-run double by Pat Burrell. The three runs appeared to hold up until the eighth inning implosion.

Because of the loss, the Giants gave up first place in the NL West to the Colorado Rockies by half a game.
