PHILADELPHIA - From his third-base coach's box, Sam Perlozzo must have waved a thousand runners home and thrown up a thousand stop signs in his career. In the complex calculus that goes into that split-second decision - the game situation, the quality of the outfielder's arm, the base runner's jump from second base - one fact stood out in Sunday night's seventh inning:  This was the Philadelphia Phillies' starting pitcher, Roy Oswalt, barreling around third, with a warmup jacket over his torso, another inning or so left in his arm and a piano on his back. Up went the stop sign, two hands thrown firmly into the air in front of Perlozzo's face.  And there went Oswalt, blowing right through it, dead to rights at home plate. And an amazing thing happened. The ball was cut off, Oswalt slid home safely, and the Phillies were about to break open Game 2 of the National League Championship Series - the way they have grown accustomed to doing every year around this time.  Oswalt's remarkable trip around the bases was one of the defining moments of the Phillies' 6-1 victory over the San Francisco Giants, which evened the series at a game apiece as it shifts to San Francisco for Tuesday's Game 3.  "I felt like he was extremely out," said Perlozzo, the Phillies' third base coach, of Oswalt. "But sometimes you get lucky."  Another defining moment: Jimmy Rollins's three-run double that followed three batters after Oswalt's base-running adventure, as the Giants' suddenly leaky bullpen turned a taut pitcher's duel - between Oswalt and Giants left-hander Jonathan Sanchez - into a rout.  And there were still other defining moments, most of them involving Oswalt sending Giants batters back to their dugout in disgrace - hey, Andres Torres, how did those four strikeouts feel? Oswalt, the second of the Phillies' three aces - preceded in Game 1 by Roy Halladay, followed in Game 3 by Cole Hamels - delivered eight sterling innings, his only blemish a solo homer allowed to the Giants' unlikely Mr. October, right fielder Cody Ross.  "I think he definitely had a chip on his shoulder," Phillies center fielder Shane Victorino said of Oswalt, who had not pitched particularly well in his previous start, in the division series against Cincinnati. "He wanted to come out and make a statement."  But it was Oswalt's bat (actually, it was revealed later, the bat belonged to Rollins) and his legs that changed the course of the game. It was his sharp single to center field leading off the seventh that got Sanchez out of the game. The young left-hander had recovered from a shaky, three-walk, 35-pitch first inning to get the Giants to the seventh trailing by only a run, 2-1.  The Phillies were thrilled to see him go. After Victorino put down a sacrifice to move Oswalt into scoring position - a strange move, given the unlikelihood that Perlozzo would ever green-light Oswalt from second on a single - and Chase Utley was intentionally walked, Phillies third baseman Placido Polanco sent a line drive into center field off reliever Ramon Ramirez.  Perlozzo had himself in the proper position, closer to home plate than to third base, and made the proper decision - stop sign. Only one problem: Oswalt was thinking "score" all the way.  "When I got halfway [around the bag], I saw the stop sign," Oswalt said. "I said, 'It's too late now. No turning back.'"
Jimmy Rollins hits a three-run double to key a four-run seventh inning and Roy Oswalt works eight stellar, three-hit innings to lead Philadelphia to a 6-1 victory over San Francisco, squaring the NLCS at one game apiece.
