SAN FRANCISCO — Brandon Crawford led off the 10th inning with a splash homer to give the San Francisco Giants a 5-4 victory over the Colorado Rockies on Sunday.
Pablo Sandoval homered and Angel Pagan drove in two runs for the Giants, who bounced back from a 1-0 loss on Saturday to take two of three in the series.
Wilin Rosario and Justin Morneau homered for the Rockies, who have lost 15 of their last 18 games in San Francisco and have not won a series here since 2010.
Crawford turned on the second pitch thrown by Rex Brothers (1-1) and drove it into McCovey Cove for his first career walkoff homer and first splash homer.
Sergio Romo (1-0) pitched a scoreless 10th for the win.
The Giants nearly won it in the ninth, when Gregor Blanco hit a drive off the wall in right field with two outs and nobody on. When Michael Cuddyer misplayed the carom off the wall, Blanco tried to score on the play but was narrowly thrown out on a relay from second baseman D.J. LeMahieu to Rosario.
The play was eerily similar to one last year when Pagan shocked the Rockies with a game-ending, two-run, inside-the-park homer in the 10th inning of a 6-5 win May 25.
Tim Hudson appeared to be cruising to this third straight win to open his San Francisco career, taking a 4-2 lead into the eighth inning having thrown only 77 pitches. The only damage came on solo homers by Rosario and Morneau.
But then Nolan Arenado and LeMahieu opened with doubles to cut the Giants lead to 4-3 and Hudson replaced by lefty specialist Javier Lopez with a man on third and one out.
Drew Stubbs pinch hit for Charlie Blackmon and grounded a game-tying single into left field to cost Hudson the win.
Hudson allowed four runs and five hits in 7 1-3 innings. He hasn’t walked a batter in 23 innings, setting a San Francisco record for most consecutive innings without a walk to open the season.
The Giants had given Hudson the lead when they broke a 17-inning scoreless streak by scoring three runs in the fifth inning against Tyler Chatwood.
Chatwood came off the disabled list from a hamstring injury to make his season debut and started strong, facing just one batter over the minimum through four innings.
But he ran into trouble after hitting Hunter Pence with a pitch to lead off the fifth. Pence later scored on a sacrifice fly by Crawford.
Pagan then added a two-run single with two outs in the inning to make it 3-1. All 10 of Pagan’s RBIs this season have come with two outs.
Sandoval added a leadoff homer in the sixth, his second of the year.
