SAN FRANCISCO -- Juan Perez, Brandon Belt and Hunter Pence hit home runs, powering the San Francisco Giants to a 7-3 victory over the San Diego Padres on Friday night in the opener of a season-ending, three-game series.
The win allowed the Giants, the defending National League West and World Series champions, to move into a tie with the Padres for third place in the division at 75-85. The Giants have won nine of their last 13 games.
Ryan Vogelsong (4-6), the third consecutive starter making perhaps his final Giants appearance as he prepares to embark on free agency, won for the first time in six starts. He gave up five hits and four walks but just two runs in six innings. He struck out three.
After Perez's first major-league home run, a two-run blast, had rallied the Giants from an early deficit, Belt followed a Tony Abreu single in the third with a shot into the right field pavilion for a 4-2 lead. The home run was the first baseman's 17th of the season.
Pence made it a three-run game with his 26th home run two batters later, giving the Giants just their second three-homer home game of the season.
All three homers came off Padres right-hander Burch Smith (1-3), who was scorched for six runs in 5 2/3 innings. He surrendered eight hits and three walks but did intersperse eight strikeouts.
The Giants padded the lead in the sixth on a bases-loaded walk by reliever Tommy Layne. The left-hander faced two batters and walked them both on eight pitches.
Gregor Blanco, who had two earlier singles, got the RBI on the bases-loaded walk.
Blanco made it a three-hit, two-RBI night with a triple in the eighth that scored Perez, who had opened the inning with his third hit, a double. Blanco was gunned down at the plate attempting for an inside-the-park home run.
Abreu also had three hits apiece for the Giants, who outhit the Padres 11-9.
Rookie standout Jedd Gyorko had three of San Diego's nine hits. Pinch-hitter Logan Forsythe's first-pitch home run off Javier Lopez in the top of the ninth capped the scoring.
The win was the Giants' 10th in 17 games against San Diego, allowing them to clinch the season series.
Gyorko had a hand in the Padres' runs in the first and third against Vogelsong. His first-inning single was sandwiched between hits by Chris Denorfia and Tommy Medica, with Medica's two-out single producing the run.
Gyorko produced his team-leading 57th RBI with a third-inning double, again scoring Denorfia. Gyorko was thrown out trying to stretch the hit into the first triple of his career.
