SAN FRANCISCO (AP) - Ryan Ludwick homered and singled off Madison Bumgarner to help give Bronson Arroyo and the Cincinnati Reds a 4-0 lead over the San Francisco Giants after six innings Sunday night in Game 2 of the NL division series.
Ryan Hanigan added a two-run single and Scott Rolen drove in a run for the Reds, who won 5-2 the previous night in the opener of the best-of-five matchup.
The day after losing starting pitcher Johnny Cueto in the first inning, Arroyo gave the Reds a dominating performance against a Giants' team he had never beaten in San Francisco.
Arroyo retired the first 14 batters he faced, including consecutive strikeouts of Brandon Belt, Gregor Blanco, Brandon Crawford and Bumgarner.
Belt singled with two outs in the fifth to end Arroyo's perfect start.
Ludwick entered the game with one hit in 16 career at_bats against Bumgarner, but he sent the first pitch he saw in the second inning over the center-field fence.
Bumgarner, who lasted 4 1-3 innings, retired Jay Bruce on an infield grounder but Rolen walked and Hanigan got ahead in the count 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.
Joey Votto and Ludwick opened the fourth with singles. After Jay Bruce fouled out to Pablo Sandoval, Rolen delivered a solid single into right field. Hanigan followed with his two-run hit.
With one out in the fifth, Zack Cozart and Votto singled, ending Bumgarner's night. George Kontos came on and got Ludwick to hit into a double play.
Bumgarner allowed four runs and seven hits. He walked one and struck out four.
Tim Lincecum came on to start the sixth for the Giants, bringing the sold out crowd of 43,505 to their feet and injecting some energy into what had been a quiet ballpark.
Lincecum got the crowd going with a perfect inning, culminating with an emphatic strikeout of Hanigan.
Arroyo was not to be denied though. He came back with a perfect sixth.
Edgar Renteria threw a strike to Giants 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 Cozart and 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 the 2010 World Series championship.
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.
