Washington, DC (Sports Network) - Ryan Zimmerman's three-run home run in the bottom of the ninth led the Washington Nationals to a 7-5 win over the Philadelphia Phillies in the second of a three-game set.

After the Phillies took a one-run lead on Carlos Ruiz's RBI single in the ninth, the Phils turned to Brad Lidge (1-1) to close the game, but it was not to be.

Mike Morse led off with a single and moved to second on Nyjer Morgan's sac bunt. Adam Kennedy followed with a walk and Zimmerman then crushed a fastball over the middle of the plate over the center-field wall for the win.

"I got hold of a good fastball there and made the most of it," said Zimmerman. "He loves to use his slider and it's a good one. That's what you'd normally look for, but I got lucky cause I was looking for a fastball."

Roger Bernadina and Josh Willingham each had an RBI and scored a run for the Nationals, who have won four of their last five. Zimmerman finished the game 2-for-4 with two runs scored.

Ross Detwiler gave up just one run on five hits with three walks and three strikeouts over 5 1/3 innings. Drew Storen (3-2) got the win in relief.

Raul Ibanez hit a two-run home run while Ruiz finished the game 3-for-5 with a solo homer and two RBI for the Phillies, who have lost two in a row since an eight-game winning streak.

Joe Blanton had a shaky start, but settled down and over six innings he gave up four runs on nine hits with a walk and eight strikeouts.

"We battled like hell there today," said Philadelphia manager Charlie Manuel. "We came from behind and did some things right, but we still ended up losing the game."

The Nationals jumped on Blanton in the first inning. With two outs and two on, Willingham flied a ball to left that Ibanez made a diving play on and got leather on the ball, but it fell out when he hit the ground and one run scored. Bernadina and Ivan Rodriguez followed with consecutive RBI singles for a 3-0 lead.

The Phils had men on base in each of the first three innings, but didn't put one across till the fourth. With a man on and one out, Domonic Brown reached base when he hit into a fielder's choice. Ruiz then belted a single to center and Wilson Valdez followed with a single to left to plate Brown and make it a 3-1 game.

With one out in the sixth, Joel Peralta took over for Detwiler and Ruiz greeted him with a shot over the wall in left to make it a one-run game.

Blanton settled down after the shaky start and didn't allow a run over the next four innings, but the Nationals did get one back in the bottom of the sixth.

Bernadina led off with a double and Rodriguez followed with a single. Ian Desmond then hit a sinking liner to right that saw Brown make a beautiful diving stop on, but Bernadina tagged up for a 4-2 lead. Willie Harris then hit a single, but Morgan grounded into a double play to end the inning.

Philly, though, tied the game in the seventh off of Tyler Clippard as Placido Polanco worked a one-out walk and Ibanez followed by drilling an 0-1 pitch into the bullpen in right for his 10th home run of the season.
