DENVER — Even when the San Francisco Giants pick up a rare win at Coors Field, they still lose.
In this case, two pitchers — starter Matt Cain and reliever Santiago Casilla, who both strained their right hamstrings and will undergo MRIs to determine the severity.
Hunter Pence hit one of San Francisco’s three solo homers and reliever Yusmeiro Petit threw three sharp innings after Cain left as the Giants beat the Colorado Rockies, 5-1, on Wednesday night.
“The win was great,” Pence said, “but it’s a huge blow to lose Cain and Casilla.”
Pablo Sandoval and Brandon Crawford also connected for the NL West-leading Giants, who won at this hitter-friendly venue for just the fifth time in 15 games dating back to last season.
Cain had good command and was cruising along, not allowing a hit through three innings. Then, on his last pitch of the third, he felt a twinge in his hamstring.
Casilla was hurt in the ninth inning when he tried to beat out an infield hit, falling over the bag and rolling several times on the field. He was helped to the dugout by the trainers and was replaced on the mound by Jeremy Affeldt, who finished the game.
To think, just moments before in the dugout, Giants manager Bruce Bochy told Casilla to not even bother swinging — just take it easy at the plate.
“I was shocked he was running like that,” Bochy said. “Guess he thought he had a hit. I don’t know what got into him. Never seen him run like that.”
Petit (3-1) pitched effectively in Cain’s place as he and four other relievers limited the best offensive team in the majors to just five hits.
