Nationals' lineup for the series finale with the Padres in Petco Park...

With a 3-1 lead after seven and a half innings, the Washington Nationals were on the way to their fourth straight win, their eighth in the last nine and their eleventh in the last thirteen, but left-handed reliever Felipe Rivero imploded and the San Diego Padres mounted a comeback with a six-run frame that gave them a 7-3 lead and eventually the win.

"That was just a series of bad events," Nationals' skipper Dusty Baker told reporters after the loss.

"That's the first time our bullpen has given it up in a game like that in a long time and I'm hoping it's another long time before it happens again."

"That was a tough one to lose tonight," Baker continued, "that was a real tough one to lose.

"But, hey, man, since I've been coming here to San Diego, this is probably the park that's had the worst kind of losses like that here, like there's always a park, sort of, but that's the end of it.

"I'm glad we're leaving tomorrow even though it's a beautiful place to be. We're ready to get out of here."

Before they leave for Los Angeles, however, the Nationals have one more to play with the Padres with Gio Gonzalez on the mound in the series finale in Petco Park opposite Padres' left-hander Drew Pomeranz.

Gonzalez, 30, tries to snap a streak of five straight winless outings, over which the Nationals are 0-5 and he's (0-4) with a 7.45 ERA and a .297/.354/.500 line against in 29 innings pitched.

In two career starts in the Padres' home, the Nats' left-hander has a 1.42 ERA and a .174/.269/.239 line against over 12 ⅔ IP.

Here's the lineup that will back Gonzalez up this afternoon in the finale of the four-game set in San Diego:

#Nats vs #Padres 4 of 4: Taylor CF, Werth LF, Harper RF, Murphy 2B, Zimmerman 1B, Rendon 3B, Espinosa SS, Lobaton C, Gonzalez P
