The Giants looked to have one foot in the NL’s Championship Series when they led 4-0 late in the game but Atlanta showed trademark grit to send the game into extra innings, before Ankiel’s spectacular winning shot.

The Braves earned 46 come-from-behind victories this season and did it again when it counted in October — 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 NL division series up for grabs. It’s the only first-round playoff series that is even after two games.

Atlanta’s Kyle Farnsworth pitched 1 2-3 shutout innings for the victory, relieving in the 10th after closer Billy Wagner got hurt fielding a sacrifice bunt. Farnsworth escaped a bases-loaded jam when Buster Posey grounded into an inning-ending double play that was started by Troy Glaus at third base.

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 postseason homer to splash into the water of McCovey Cove. Home run king Barry Bonds hit the other in 2002.

In Philadelphia, the hosts took advantage of some sloppy Cincinnati defense to beat the Reds, taking a 2-0 lead in their best-of-five NLDS.

Reds right fielder Jay Bruce missed a line drive in the seventh inning, allowing two runs to score, as Philadelphia went from no offense in game 1 when Roy Halladay threw a no-hitter, to no defense in game 2.

Cincinnati’s Brandon Phillips hit a leadoff homer on Roy Oswalt’s fourth pitch and the Reds built a 4-0 lead before their defense and bullpen unraveled.

The Phillies rallied against hard-throwing rookie Aroldis Chapman and his triple-digit fastball after soft-tossing starter Bronson Arroyo kept Philadelphia’s hitters off balance.

Leading 4-3, the Reds turned to Chapman to protect the slim margin in the seventh, but the Cuban hit Chase Utley with a fastball leading off.

After a strike out, Jayson Werth hit a bouncer to third baseman Scott Rolen. Utley beat the throw to second on a close call.

Jimmy Rollins then hit a liner to right that Bruce turned into a two-base error. Bruce appeared to lose the ball in the lights. It rolled past him and Utley scored the tying run. Werth scored without a play when Phillips dropped the relay throw for another error, and the Phillies took a 5-4 lead.

Raul Ibanez followed with a single and Carlos Ruiz hit an RBI grounder for a 6-4 lead.

Werth hit an RBI single in the eighth to cap the scoring.

Philadelphia reliever Jose Contreras tossed a perfect seventh to earn the win.

Game 3 is Sunday in Cincinnati. Cole Hamels, the 2008 World Series MVP, pitches for the Phillies. Johnny Cueto is on the mound for the Reds.
