PHILADELPHIA -- Kenny Lofton didn't wait long to show his new teammates what he can do.

The six-time All-Star homered in his first at-bat with the San Francisco Giants on Tuesday night against the Philadelphia Phillies, starting his new team toward a 10-3 romp.

Just five weeks after leaving Veterans Stadium with the Chicago White Sox, Lofton was back in the visiting clubhouse in Philadelphia. He was also back in a pennant race.

The Giants entered the day six games behind first-place Arizona in the NL West and one game behind Los Angeles in the wild card race. Chicago was 14 games behind Minnesota in the AL Central.

"It's always exciting when every game you play means a lot,'' said Lofton, acquired from the White Sox for two minor league pitchers on Sunday.

The speedy Lofton was a welcome sight for manager Dusty Baker, whose outfield has been decimated by injuries.

"He's a proven winner. He can play,'' Baker said. "He has a lot of speed and that's one thing we need on this team.''

But Baker wasn't expecting to get power from Lofton, who hit rookie Brett Myers' second pitch over the left-center fence for his 24th career leadoff homer. Lofton later added a triple.

San Francisco was still missing left fielder Barry Bonds, out with a hamstring injury. Outfielders Tsuyoshi Shinjo and Marvin Benard remained on the disabled list, but right fielder Reggie Sanders was back in the lineup after missing five games with a strained right hamstring.

Shinjo, batting .237 with eight homers and 32 RBI, realizes his playing time will diminish with Lofton's arrival.

"I'm not surprised at all,'' Shinjo said through a translator. "I'm not disappointed. All I can do is, whenever I get an opportunity, do my best.''

Lofton hit .259 with eight homers, 42 RBI and 68 runs for Chicago this season. He stole 22 bases, but only one in his last 36 games because he was slowed by a hamstring injury.

The 35-year-old center fielder was so eager to play for a winning team that he dropped a clause in his contract with the White Sox that guaranteed a significant bonus if the team reached a certain attendance threshold.

The Giants, who play in packed Pacific Bell Park, will certainly reach the mark.

"I just want to get acclimated,'' Lofton said. "It should be fun.''
