The Reds ended innings with runners in scoring position on three separate occasions before David Ross doubled to lead off the ninth. Griffey followed followed by sending Pirates closer Matt Capp's 0-1 pitch over the right-center-field wall for his 603rd career home run.

The win pulled Cincinnati into a virtual tie with Pittsburgh for fifth place in the National League Central and snapped a five-game home losing streak.

Aaron Harang, a winner in just one of his past 10 starts, pitched seven solid innings and gave up three runs on seven hits with a walk and eight strikeouts.

The Reds twice had runners on the corners with one out, but managed just one run. Their other run came on Jerry Hairston's leadoff home run in the third inning.

Pittsburgh took a 1-0 lead in the second when Ryan Doumit doubled and came around to score on a sacrifice fly from Adam LaRoche.

Harang (3-10) gave up another double, this time to Xavier Nady, with one out in the sixth. LaRoche logged his second and third RBIs of the game when he sent Harang's 0-1 fastball 402 feet into the right-center-field seats for a 3-1 Pirates lead.

Brandon Phillips singled up the middle in the bottom of the sixth and Pirates starter Paul Maholm (5-5) loaded the bases when he walked Joey Votto and hit Edwin Encarnacion with a pitch. Jay Bruce grounded out to first, which scored Phillips and pulled the Reds within one, before Ross struck out looking to end the inning.
