SAN FRANCISCO -- One dramatic hit will not make up for Ray Durham's down season -- yet it sure brightened the Giants' mood for a day against their archrivals.
Durham stepped in as a pinch-hitter and had a go-ahead, three-run homer in the eighth inning, and the Los Angeles Dodgers missed another chance to gain ground in the playoff race with a 4-2 loss to San Francisco on Sunday.
"That might be the best thing that's happened to him all year," starting pitcher Matt Cain said. "So deserving, too. He's working his tail off."
Jeff Kent homered twice against his former club but the Dodgers couldn't hold a late lead and failed to move closer to the Padres, who lost at Colorado. San Diego remained 2½ games up on Los Angeles in the NL wild-card chase.
Never miss a local story.
Durham was behind 0-2 when he connected for his 11th homer of the year with a shot to the right-field arcade.
Dodgers manager Grady Little made three pitching changes in the eighth to try to escape trouble.
All-Star Brad Penny was done after allowing Kevin Frandsen's leadoff double. Scott Proctor's wild pitch sent Frandsen to third, then Randy Winn struck out before Joe Beimel (4-2) relieved to face Barry Bonds.
Bonds was intentionally walked and replaced by pinch-runner Rajai Davis. Little then went to Jonathan Broxton to face Durham.
