Asked before the game about beating Cain with a lineup brimming with young players, manager Jim Tracy said, "This task that we have today is monumental. I mean, let's face it. When you look at the kids we have in that lineup playing against these guys ..."
Tracy was right. But the job at hand was made more difficult by a horrible outing from righty Esmil Rogers as the Rockies lost 12-5 and were swept in the four-game series.
The loss dropped the Rockies' record to 70-82 and assures them of their first losing season since 2008 (74-88).
Rogers allowed seven hits, including a career-high four home runs, and a career-high nine runs in 3 2/3 innings with two walks and no strikeouts. He gave up three of the four homers the Giants hit in their eight-run third when they built a 10-1 lead.
Rogers is 6-6 with a 6.64 ERA in 16 games, including 13 starts. At Coors Field, Rogers is 1-3 with an 11.68 ERA in six games, including five starts.
He began the game with a walk, and Mike Fontenot followed with a two-run homer. Rogers gave up a one-out triple to Pablo Sandoval but retired Aubrey Huff and Brandon Belt. After setting the Giants down in order in the second, Rogers imploded in the third.
Sandoval began the inning with a home run and Brandon Belt homered with one out. After Brandon Crawford doubled, Rogers got a second out, but pitcher Matt Cain homered over the center-field fence.
Rogers walked Andres Torres, hit Fontenot with a pitch, gave up a run-scoring single to Carlos Beltran and was relieved by Greg Reynolds.
Sandoval greeted him with a three-run homer, two of those runs charged to Rogers.
"The ball was very true going through the strike zone, somewhere between the belt and the mid-thigh area virtually the entire time he was out there," Tracy said. "When you do that, especially in this ballpark....
"You know what? This ballpark? It doesn't really matter. Any ballpark, to pitch from the mid-thigh to the belt on the better part of the plate, you're going to get hit by good big league hitters."
