DETROIT -- Manager Jim Leyland's smart choice for a pinch hitter paid off in a big way for the Detroit Tigers.
Placido Polanco's pinch-hit single in the eighth inning broke a scoreless tie and Nate Robertson tossed 7 1/3 innings to help Detroit beat the Cincinnati Reds 1-0 Sunday.
Polanco, the team's regular second baseman, wasn't in the starting lineup because Leyland rested him after Saturday night's win. Ramon Santiago started at second and was in Polanco's usual spot, second in the batting order.
But with runners on first and third with one out in the eighth, Polanco was sent to the plate.
"I knew he wasn't going to strike out," Leyland said. "If he hits it on the ground, he could hit into a double play, but so would most of the of the other guys on the team."
The base hit to right scored Brandon Inge from third. Inge led off with a walk and moved to third on a sacrifice and a throwing error by Cincinnati starter Aaron Harang.
"I just tried to stay inside the ball," said Polanco, a right-handed hitter. "I try to hit the ball to right field a lot."
Harang said the throwing error, which came on Vance Wilson's sacrifice bunt, was the key.
"That throw cost me the game," he said. "I tried to backhand it and it hit my glove and the throw got away."
Robertson struck out seven, walked five and allowed three hits. Fernando Rodney (3-1) and Todd Jones combined to throw 1 2/3 hitless innings with Jones getting his 13th save in 14 opportunities. Jones set a franchise record with his 155th save with the Tigers, moving one ahead of Mike Henneman.
Detroit has won nine of its last 10 games and have posted eight shutout wins this season.
Rodney (3-1) entered with Felipe Lopez on first and one out in the eighth. Lopez was thrown out attempting to steal second, and Rodney retired the next batter.
Robertson set down the first nine batters he faced before walking Ryan Freel to lead off the fourth. After Lopez struck out, Ken Griffey Jr. notched the Reds' first hit when he lined a ground-rule double into the right-field corner to send Freel to third. Rich Aurilia then lined to third and Austin Kearns walked to load the bases. But Robertson escaped the jam by striking out Adam Dunn on a 3-2 pitch.
The Reds threatened again in the seventh when Dunn led off with a single and went to third on Edwin Encarnacion's double. But the next three batters hit grounders to Inge at third.
"We had some chances early where we didn't get guys in," Cincinnati manager Jerry Narron said. "You get second and third with nobody out and hit three straight balls to third base ... that isn't real good."
Dunn tried to score on the second grounder but Inge threw to Wilson, the catcher, who tagged out the 6-foot-6, 275-pound Dunn and deftly stepped out of the way to avoid the brunt of the contact.
"Brandon made a great throw," Wilson said. "I was just trying to tag him and get out of the way as soon as possible."
Harang (5-3) pitched eight innings for the third complete game of his career. He allowed five hits and the lone run, striking out eight and walking one.
After Chris Shelton's one-out single in the second, Harang retired the next 15 batters before Magglio Ordonez singled with one out in the seventh.
Curtis Granderson led off the game with a double against Harang and moved to third on a sacrifice. But Carlos Guillen popped out and Ordonez flied out to center to end the inning.
The Tigers also had runners on first and third with two out in the seventh but Harang struck out Craig Monroe on three pitches.
