The Giants' new secret to success: Hit grand slams. They've won only twice in the last seven games, and each win came courtesy of a four-run homer.

Brandon Crawford hit a grand slam in his first big-league game Friday, helping the Giants beat the Brewers.

Monday, it was Andres Torres' turn. His slam help beat the Cardinals 7-3 in the opener of a four-game series in St. Louis.

In games in which the Giants didn't hit a grand slam, they have lost five in a row.

Not exactly a promising way to do business -- grand slam or bust -- but the Giants were thrilled with the rare offensive outburst Monday, a far cry from other games played of late.

It was Torres' third career grand slam. Aaron Rowand doubled home a run, and the based filled on Crawford's single and pitcher Madison Bumgarner's walk. Ross hit the second pitch of the at-bat over the wall off Kyle McLellan.
