San Francisco ? Rick Ankiel and the Atlanta Braves came through with another comeback when they absolutely needed one.

San Francisco catcher Buster Posey, left, collides with Pablo Sandoval while chasing a pop foul ball. The Giants fell to the Braves, 5-4 in 11 innings, on Friday in San Francisco.

Ankiel splashed a tiebreaking home run into McCovey Cove in the 11th inning for his first postseason clout, and Atlanta rallied from a late four-run deficit to beat the San Francisco Giants, 5-4, on Friday night, tying their NL division series at a game apiece.

The Braves earned 46 come-from-behind victories this season and did it again when it mattered most — with manager Bobby Cox watching from the clubhouse after his third career postseason ejection way back in the second inning.

Atlanta heads home to Turner Field for Game 3 on Sunday with the best-of-five series all square. It’s the only first-round playoff series that is even after two games.

Kyle Farnsworth pitched 12?3 shutout innings for the victory, relieving in the 10th after closer Billy Wagner got hurt. Farnsworth escaped a bases-loaded jam when Buster Posey grounded into an inning-ending double play that was started by third baseman Troy Glaus.

Alex Gonzalez hit a tying, two-run double in the eighth against Giants closer Brian Wilson, who led the majors with 48 saves this season.

Ankiel’s drive on a 2-2 pitch from Ramon Ramirez was just the second splash homer in the postseason at 11-year-old AT&T Park. Home run king Barry Bonds hit the other one on Oct. 10, 2002, in Game 2 of the NL championship series against St. Louis.

Posey grounded into 5-4-3 double play, keeping the score tied at 4. Wagner, who plans to retire after the season, first grabbed at his left side after chasing pinch-hitter Edgar Renteria’s bunt single to start the 10th inning.

The left-hander then fielded Andres Torres’ sacrifice bunt back to the mound, threw to first for the out and immediately grabbed at the area near his left hip before crumbling to his knees.

The 39-year-old Wagner walked slowly off the field with a trainer and was replaced by Farnsworth, who was given all the time he needed to warm up.

Farnsworth hit Freddy Sanchez in the right hand on his third pitch. Sanchez went down writhing in pain, but he went to first base.
