Washington grabbed a six-game lead in the NL East, handing Atlanta its third straight loss. Ian Desmond led off the 13th with an infield single off Cristhian Martinez (5-3) before Danny Espinosa tried to bunt and hit into a forceout. Kurt Suzuki then hit a slow roller for an infield hit, allowing Espinosa to take third. With the infield in, Tracy hit a ball to Braves second baseman Dan Uggla, who appeared confused and instead of either trying to get Espinosa at the plate or attempting to turn a double play, he fumbled it, and Espinosa scored the game-winner. Craig Stammen (6-1) pitched two hitless innings for the win. Phillies 12, Reds 5: John Mayberry Jr. hit a two-run homer and Ryan Howard and Erik Kratz had solo shots to help Roy Halladay get the victory for Philadelphia. Halladay (7-7) wasn't sharp, allowing five runs and 10 hits in seven innings. But the offense bailed out the two-time Cy Young Award winner. Domonic Brown hit a go-ahead two-run double off Mike Leake (5-8) in a four-run fifth. Mayberry had three hits and three RBIs, and Chase Utley, Howard and Kratz each drove in two. Juan Pierre had three hits and scored three times. The Phillies have won seven straight over the Reds and 12 of 13, dating to 2010. This was their first meeting this season. The NL Central-leading Reds lost for just the third time in 11 games. Marlins 12, Diamondbacks 3: Giancarlo Stanton homered twice, including the first of back-to-back home runs during Miami's nine-run fourth inning. Justin Ruggiano homered after Stanton, and Jose Reyes had four hits — including three doubles — scored twice and drove in a run for the Marlins, who have won three of four. Miami's 10 hits in the fourth matched a franchise record set last September 9 at Pittsburgh and the 12 runs and 20 hits were season highs. Brewers 9, Cubs 5: Jonathan Lucroy hit two home runs and the Brewers scored eight runs in the fifth inning to rally for the victory. Rockies 3, Mets 1: Tyler Colvin hit a tying homer off R.A. Dickey in the fifth inning, then made a diving play in the eighth to help Colorado get the victory. Padres 3, Pirates 1: Edinson Volquez struck out 10 and Will Venable drove in two runs to lift the Padres to a victory over the Pirates. Giants 2, Dodgers 1: Madison Bumgarner scattered four hits over eight scoreless innings, Pablo Sandoval drove in both runs and the Giants defeated the Dodgers to regain the NL West lead by a half-game. — Agencies
