San Francisco ? Juan Uribe, sore left wrist and all, made his mark on this NLCS in a matter of moments — a great play with his glove, then one swing that put the San Francisco Giants within one win of the World Series.

A champion with the White Sox in 2005, Uribe hit a game-ending sacrifice fly off reliever Roy Oswalt with one out in the ninth inning that lifted the Giants over the Philadelphia Phillies, 6-5, Wednesday night for a 3-1 lead in the NL championship series.

Aubrey Huff singled with one out in the ninth and took third when Buster Posey singled for his fourth hit of the game. Uribe hit a medium-deep fly, leaving left fielder Ben Francisco with no chance to get the sliding Huff.

“I got butterflies,” winning pitcher Brian Wilson said. “I got anxiety. I got a mini-ulcer developing, but it’s all worth it. We never lost focus.”

Boosted by yet another big hit from Cody Ross and a timely double from Pablo Sandoval, the Giants pushed the two-time defending NL champion Phillies to the brink of elimination. Philadelphia will send Roy Halladay against Tim Lincecum in Game 5 tonight — it’s a rematch of aces that Lincecum won in the opener.

“We know what is at stake, but the game is the same. We have an opportunity to win a game tomorrow,” Phillies shortstop Jimmy Rollins said.

Going to Oswalt to begin the ninth backed manager Charlie Manuel’s words this was his club’s biggest game yet this year. Oswalt is one of the majors’ top starters and beat the Giants in Game 2. He’s made only a few relief appearances in the last several years, including a stint in the 2004 NLCS for Houston.

Uribe entered at shortstop in the top of the ninth. He immediately picked up a hard one-hopper by pinch-hitter Ross Gload in the hole and made a strong throw while falling away for the out.

Wilson, the major league saves leader, pitched a perfect ninth.
