Neil Walker went 3-for-4 and knocked in a ahead run in the seventh inning, as the Pittsburgh 3, in the middle test of a three-game series.

Tony Watson (1-2) entered a tie game in the top of the seventh and stranded Ramon Hernandez at second to record his first major league win.

Joel Hanrahan, who allowed three ninth-inning runs in Friday's 11-8 series-opening loss, recorded the game's final three outs to earn his 31st save of the season.

Hernandez had tied the game at 3-3 with an RBI double, but Aroldis Chapman (2-1) surrendered two runs a half-inning later to suffer the loss.
