CINCINNATI Third baseman Scott Rolens error with two outs in the 10th inning gave San Francisco the go-ahead run, and the Giants edged the Cincinnati Reds 2-1 on Tuesday night to cut their NL playoff deficit to 2-1.
The Giants avoided a division series sweep when Rolen, an eight-time Gold Glove winner, bobbled Joaquin Arias short-hop grounder and threw late to first.
San Francisco was held hitless into the sixth by Homer Bailey, managed only three hits overall and struck out 16 times.
But the Giants got two hits in the 10th and were helped by a passed ball.
Left-hander Barry Zito will start Game 4 today for the Giants, who have won the last 11 games hes started.
The Reds have to decide whether to try ace Johnny Cueto, forced out of the opener with spasms in his back and side.
The Reds havent won a home playoff game since 1995, the last time they reached the NL championship series. One win away from making it back there, they couldnt beat a Giants team that barely has been able to get a hit.
They didnt need many in this Game 3.
Bailey made his first start at Great American Ball Park since his Sept. 28 no-hitter in Pittsburgh and allowed only one hit in seven innings, the latest dominating performance by a Reds starter. Marco Scutaro singled in the sixth for the only hit off Bailey.
OAKLAND, Calif. Brett Anderson outdueled fellow postseason first-timer Anibal Sanchez and received stellar defense all over the diamond, and the upstart Oakland Athletics avoided another playoff sweep by Detroit, beating the Tigers 2-0 Tuesday night in their AL division series.
The As cut their deficit in the best-of-five matchup to 2-1.
Coco Crisp saved a likely home run by Prince Fielder with a leaping catch at the top of the center-field wall in the second and the As will play another day in this improbable season full of remarkable rallies.
Yoenis Cespedes hit an RBI single in the first inning, and Seth Smith homered later.
