Wood was traded to the Cubs for left-handed reliever Sean Marshall after the 2011 season. He had pitched well against the Reds, allowing only two runs in three of his four starts against them this season.
He didn't need much help this time.
"The luck he's had this year, it's just gratifying to see him get a win at any time," Cubs manager Dale Sveum said. "He's had some tough luck this year."
Wood forced Cincinnati to strand a runner at second base in the first, third, fourth, fifth and sixth innings. After Shin-Soo Choo doubled with one out in the fifth, Wood got Brandon Phillips and Joey Votto on called third strikes.
The Reds stranded seven runners in scoring position in seven innings.
"He's an All-Star," Reds manager Dusty Baker said. "He was able to make his pitches when he needed to. We had men in scoring position seven times in the game. We just couldn't get that hit tonight. "
Choo was hit in the back with a pitch in the third inning, the 25th time the leadoff hitter has been plunked this season. With that, Choo surpassed Jason LaRue for the club record.
Notes: It was the Cubs' sixth shutout this season. ... Reds SS Zack Cozart had two doubles, extending his hitting streak to a career-high 14 games. ... RHP Johnny Cueto continues to throw without pain. Cueto is on the DL for the third time this season with shoulder problems. The Reds haven't decided when he could pitch in a game or what role he might have. "You don't want to force him in there and end up hurting his shoulder," Baker said. "It's great to have him as a possibility." ... LHP Tony Cingrani (7-3) starts for the Reds on Tuesday, his second appearance since returning from back spasms. The Cubs go with Edwin Jackson (7-15), who leads the NL in losses.
