Rockies beat Giants to go 4-0 at AT&T Park

With the season nearing its midpoint, the Giants are entrenched in survival mode, trying to stay afloat until two starting pitchers return, with their entire projected Opening Day outfield injured and a key reliever making a fresh trip to the disabled list.

Angel Pagan was too hurt to play in Friday night’s series opener against the Rockies, his left knee bruised when he crashed into the center-field wall Thursday.

Lopez allowed two hits to left-handed hitters that produced three runs and propelled Colorado to an 8-6 victory, its fourth in four games at AT&T Park this season.

Lopez relieved Tim Hudson with two outs and two on in the inning and allowed Carlos Gonzalez’s tie-breaking double and Ben Paulsen’s two-run single.

The Rockies added two in the ninth against just-recalled Mike Broadway, one on Nolan Arenado’s second homer of the game, and Carlos Gonzalez had a five-hit game to help the last-place team in the West cruise to its seventh win in 10 games against the Giants this year.

Matt Duffy came within two inches of possibly tying the game with a two-run double down the right-field line, but the ball was foul.

Before the game, the Giants announced left-hander Jeremy Affeldt was out with a shoulder strain, Bochy then revealed that Pagan had X-rays and an MRI exam on his knee and might join Affeldt — and outfielders Nori Aoki and Hunter Pence — on the disabled list.

Hudson carried a shutout into the sixth and already reached a season-high six strikeouts served up a three-run blast by Arenado that traveled halfway up the left-field bleachers.
