PHILADELPHIA -- One timely hit at a time, Washington wiped out a four-run deficit. The bullpen took care of the rest, using a near-flawless effort to help the Nationals keep pace in the NL wild-card race.
"When you're able to come back in the fashion that we did, it breeds confidence," said Preston Wilson, who had the game-tying single in the eighth.
The Nationals had been shut down twice in the late innings by Philadelphia's bullpen the last two games only to rally against Ugueth Urbina (3-1) in the eighth.
Urbina pitched a scoreless eighth the last two games against the Nationals -- including one stint only hours earlier -- but blew a 4-3 lead and wasted a chance for the Phillies to build on their wild-card lead.
Jose Guillen opened the eighth with a double and scored on Wilson's game-tying single to left. Then Baerga followed with the single to center and helped the Nationals gain a split of the four-game series.
"If we can do that more often, we're going to win our share of games," Nationals manager Frank Robinson said.
The Phillies began the day tied for the wild-card lead with Houston -- which lost 5-2 to Milwaukee on Thursday night -- and a half-game ahead of the Nationals.
Luis Ayala (8-6) earned the win for Washington with two scoreless innings of relief. John Halama threw one scoreless inning and Mike Stanton got one out in the eighth. Chad Cordero pitched the final 1 2/3 innings for his 39th save.
"We just had to go out there and do what we were supposed to do," Cordero said. "We try not to put too much pressure on ourselves and it came out pretty good."
Chase Utley gave the Phillies a 3-0 lead with a sacrifice fly in the first and his 17th homer of the year in the third, a two-run shot off starter Ryan Drese. David Bell added an RBI double in the fourth.
The Nationals rallied against Phillies starter Cory Lidle, who has only one win in his last eight starts. Lidle gave up six hits and three runs in five innings.
"Lidle got a little tired. He lost command of his pitches," Phillies manager Charlie Manuel said.
Then Washington's bullpen took over, pitching three-hit ball and striking out four over five scoreless innings.
"They came in and did the job for us," Robinson said.
- A rainout Tuesday caused the doubleheader.
- Manuel said he'll likely give LHP Eude Brito the start against Pittsburgh on Sunday. Manuel said it was still too early in the season to bring back Wednesday night's starter Jon Lieber on three days' rest.
- This was the fourth doubleheader in the two-year history of Citizens Bank Park. Padilla won the first game in two others.
