SAN FRANCISCO (AP) - Ryan Ludwick homered off Madison Bumgarner to give Bronson Arroyo and the Cincinnati Reds a 1-0 lead over the San Francisco Giants after three innings Sunday night in Game 2 of the NL division series.
The Reds won 5-2 the previous night in the opener of the best-of-five matchup.
Arroyo retired the first nine batters he faced, including consecutive strikeouts of Brandon Belt, Gregor Blanco, Brandon Crawford and Bumgarner.
Ludwick entered the game with one hit in 16 career at_bats against Bumgarner. Ludwick sent the first pitch he saw in the second inning over the center-field fence.
Bumgarner retired Jay Bruce on an infield grounder but Scott Rolen and fell behind Ryan Hanigan 2-0.
Following a visit from Giants pitching Dave Righetti, Bumgarner came back to strike out Hanigan and retire Drew Stubbs on a soft liner.
Bumgarner pitched a perfect third. He had four strikeouts and one walk through the early innings.
Former Giants shortstop Edgar Renteria, MVP of the World Series championship, threw a strike to San Francisco reliever Sergio Romo for the game's ceremonial first pitch moments after a Blue Angels fly-by.
Bumgarner followed Renteria's example, getting Brandon Phillips to foul out to Buster Posey and striking out both Zack Cozart and Joey Votto in the top of the first.
Bumgarner was 2-0 with a 2.18 ERA in four appearances, including three starts, during the Giants' run to that 2010 title.
Arroyo made his 12th career postseason appearance, his fourth start. He's 0-4 with a 4.11 ERA in six appearances, five starts, at AT&T Park. He last beat the Giants on Aug. 31, 2008.
NFL Hall of Fame quarterback Joe Montana earned a standing ovation from the crowd when he was shown on the scoreboard before the top of the third. Actor Charlie Sheen, decked out in Cincinnati gear, was met with a round of boos when he was shown on the scoreboard the following the next half-inning.
