PHILADELPHIA (Reuters) - Rookie pitcher Vance Worley tossed a complete game to guide the Philadelphia Phillies to a 7-2 win over World Series champions San Francisco on Tuesday.

It was the first career complete game for Worley (7-1), who has thrived since stepping into Philadelphia's starting rotation this season because of injuries.

"It's cool, he's hitting his spots," Phillies catcher Brian Schneider told reporters. "I can call as many pitches as I want, but he's still got to throw the ball."

San Francisco (59-44) ace Tim Lincecum was scratched from his expected start before the game with a stomach illness, and replacement Barry Zito (3-3) was attacked early on his way to six allowed runs.

Raul Ibanez blasted a three-run home run in the first inning to give the Phillies a 4-1 lead, while Chase Utley wowed the crowd with an inside-the-park homer in the sixth.

Utley hit a ball deep to center field that ricocheted into right field and allowed him to motor around the bases and give his team a 6-1 advantage.

"I saw the ball kick off the wall and I knew there was a possibility," Utley said. "I kind of lost my legs a little bit there. We don't practice that one too much."

Aaron Rowand homered in the eighth for the NL West-leading Giants, who had taken a 1-0 lead in the top of the first.

Ryan Howard went 2-for-4 and capped the scoring with a blast in the eighth to help Major League-best Philadelphia (65-37) capture its sixth win in seven games.
