SAN FRANCISCO -- Just when it seemed the San Diego Padres were sinking in the season's final week, Brian Giles provided a big boost with one powerful swing.
Giles hit a go-ahead three-run homer with two outs in the ninth, and the Padres ended a four-game losing streak with a 6-4 victory over the San Francisco Giants on Tuesday night.
The win gave San Diego a one-game lead over Philadelphia in the wild-card standings after the Phillies lost 10-6 to Atlanta. And the Padres also pulled within two games of NL West-leading Arizona, which lost 6-5 at Pittsburgh.
Giles, who was in a 4-for-52 slump, hit his 12th home run of the season off closer Brian Wilson (1-2) and spoiled another strong outing by Giants starter Matt Cain. whose winless stretch reached five consecutive starts. Cain hasn't won since Aug. 28 against Colorado.
