Pirates 3, Reds 2: Vance Worley pitched 6 1/3 solid innings and Neil Walker slugged a three-run homer as host Pittsburgh took its second straight from Cincinnati.

Worley (6-4) allowed two runs - one earned - and a season-low three hits to snap a personal three-game losing streak and help the Pirates stay one game behind St. Louis in the race for the second wild card in the National League. Andrew Lambo had a single and a run scored and Mark Melancon picked up his 26th save as Pittsburgh pulled within two games of division-leading Milwaukee.

Alfredo Simon (13-9) let up three runs on four hits while striking out seven in seven frames to get saddled with a tough loss. Todd Frazier clubbed his 23rd homer for the Reds, who are 7 1/2 games behind the second wild card.

Lambo singled with one out in the first and Andrew McCutchen drew a walk before Walker cranked his 18th home run of the year for a 3-0 lead. Frazier notched Cincinnati's first hit with a one-out blast in the fourth to cut the deficit to 3-1.

Devin Mesoraco was hit by a pitch with one out in the seventh, moved to second on a single that chased Worley and scored on a botched popup by first baseman Ike Davis to make it 3-2. Justin Wilson got the Pirates out of that mess, Tony Watson breezed through the eighth and Melancon survived Mesoraco's drive to the warning track in left in a 1-2-3 ninth.
