Carlos Baerga's go-ahead single in the eighth inning lifted Washington to a 5-4 victory and a split of a day-night doubleheader against the Philadelphia Phillies last night at Citizens Bank Park.

In the opener, Vicente Padilla kept up his recent run of outstanding starts and Bobby Abreu delivered a key two-run double in Philadelphia's 2-1 win.

The Nationals had been shut down twice in the late innings by Philadelphia's bullpen the past two games only to rally against Ugueth Urbina (3-1) in the eighth.

Urbina pitched a scoreless eighth the previous two games against the Nationals -- including one stint only hours earlier -- but blew a 4-3 lead.

Jose Guillen opened the eighth with a double and scored on Preston Wilson's game-tying single to left. Baerga followed with a single to help the Nationals gain a split of the four-game series.

Luis Ayala (8-6) earned the win for Washington with two scoreless innings of relief. Chad Cordero pitched the final 1 2/3 innings for his 39th save.

Padilla (6-11) gave up one run and six hits in six innings, holding the lead after Abreu's two-run double in the third. Billy Wagner worked the ninth for his 29th save.
