Pirates 4, Reds 3 (12) : Russell Martin walked with the bases loaded in the bottom of the 12th inning as Pittsburgh salvaged the finale of the three-game series.

After Andrew McCutchen flew out to deep right-center to start the 12th, Gaby Sanchez delivered a line-drive single to center against Tony Cingrani (2-8) and advanced to second on a balk. Josh Harrison was intentionally walked, Jordy Mercer struck out and Clint Barmes was hit by a pitch to set the stage for Martin.

Gregory Polanco recorded two hits to set a team record by hitting safely in his first nine career contests for Pittsburgh, which snapped a three-game slide. Starling Marte and McCutchen recorded RBIs, Barmes matched a career high with four hits and Justin Wilson (2-0) earned the victory by pitching a scoreless 12th.

Cincinnati's Devin Mesoraco belted a game-tying solo homer in the ninth on his 26th birthday against closer Jason Grilli, who took the loss in the Reds' 6-5 win Tuesday. Joey Votto and Jay Bruce added RBIs for Cincinnati, which had its three-game winning streak snapped while losing for the second time in eight games.

Barmes and Chris Stewart started Pittsburgh's three-run fifth with one-out back-to-back singles and after Barmes advanced to third on a fielder's choice bunt by Locke, Reds starter Homer Bailey balked him home. Polanco followed with an infield hit before Marte and McCutchen delivered run-scoring singles to make it 3-2.
