SAN FRANCISCO � Freddy Sanchez pumped his fist after his fifth-inning double to right-center field drove in two runs and tied the score. A few moments later, the crowd of 42,744 at AT&T Park erupted after Sanchez crossed the plate for the eventual winning run.

�Obviously, I�ve never been in a big league playoff run,� Sanchez said. �It�s fun, it�s exciting. Every play�s a big play.�
In his first game in a Giants uniform, Sanchez made his presence felt, going 2 for 4 during a 7-3 victory over the Philadelphia Phillies on Sunday as San Francisco took three of four games from the defending World Series champions.
Leadoff hitter Eugenio Velez went 2 for 5 with a clutch two-run single in the sixth inning as the Giants wrapped up a seven-game homestand with six wins to stay tied atop the National League wild-card standings.
�We�ve had some good (series) here at home,� Manager Bruce Bochy said, �but I would put (this one) up there.�
Sanchez, acquired Wednesday from Pittsburgh for pitching prospect Tim Alderson, was in an 0-for-17 slump and had not played since July 26 because of a sore left knee.
But Sanchez worked out Saturday with no problems and was inserted into the lineup as the No. 2 hitter. He received a huge ovation during pregame introductions, and quickly ended his slump with a sharply hit first-inning single that bounced off the glove of shortstop Jimmy Rollins.
In the fifth with the Giants trailing 3-1, Sanchez�s double off Phillies starter Cole Hamels scored pitcher Barry Zito � who started the rally with a two-out single to center � from third and Velez from first. Sanchez scored when Pablo Sandoval grounded a single to Ryan Howard and the first baseman backhanded a throw over Hamels, who was covering the bag.
�I just tried to put the ball in play,� Sanchez said. �(Hamels) is one of the best pitchers in the game. I feel like any time you put the ball in play, you have a chance to make something happen.�
Sanchez�s only miscue came in the fourth inning when the second baseman fielded a bloop single by Jayson Werth and rushed a throw to first baseman Ryan Garko. The throw was in the dirt and skipped off Garko�s glove before it wound up in shallow right field, allowing Chase Utley to score Philadelphia�s second run.
The Phillies scored again in the fifth, but Zito (7-10) retired the last five batters he faced.
�Everything started that inning,� said Zito, who hasn�t allowed a walk in three of his past five starts. �A two-out single, and Velez and Sanchez had huge hits.�
Center fielder Aaron Rowand, who declared himself fit to play Sunday after taking a Joe Blanton pitch just above the left elbow Saturday, went 2 for 4 and finished the series 4 for 9 with two doubles and a triple.
�Any time you make a move at the deadline and bring in a guy like Freddy and have him finally get into the lineup, it kind of gives everybody a boost,� Rowand said. �He�s a heck of a player. To watch him go out there, play his game and do the things that I�ve watched him do for years, to have him on our side is great.�
