It’s always a good thing when the Giants are able to get a win in Coord Field, a place that has been a place of utter frustation for the road team over the years.

Wednesday night’s 5-1 win over the Colorado Rockies erased the memory of the previous night’s dramatic loss. At the same time, however, it created more issues that look like they will last longer than any loss would.

Starter Matt Cain had to leave the game in the third after suffering a slight hamstring injury following a strikeout to end the inning. The encouraging thing, however, is that Cain was able to walk off the field on his own power.

The timetable to return was not immediately determined at press time.

Santiago Casilla’s injury appears to be considerably serious and drastically shifted the mood of the entire Giants dugout.

Casilla, who was solid in relief on Wednesday, came up to bat in the top of the ninth – this was only his fifth career at-bat – and worked the count to 3-2 to the delight of his teammates, including Pablo Sandoval.

That quickly changed when he hit a dribbler up the middle, which shortstop Troy Tulowitzki gobbled up and threw out a hustling Casilla.

The righty then fell to the turf in serious pain, and he was eventually helped off the field by two trainers, as Casilla was unable to put weight on either leg as he was helped into the clubhouse following the play.

“I was shocked that he was running like that,” manager Bruce Bochy said. “I told him, ‘Don’t even swing.’ I’ve never seen him run like that. I guess when he hit it, he thought he had a hit.”

Jeremy Affeldt entered in the ninth and was able to pick up the save to even up the series at 1-1.
