Nationals 8, Padres 3

WASHINGTON -- Stephen Strasburg allowed just two runs in six innings, center fielder Denard Span returned to the lineup and Ryan Zimmerman hit a grand slam as the Washington Nationals beat the San Diego Padres 8-3 on Tuesday.

The Nationals (63-61), who began the day 5 1/2 games back of the first-place New York Mets, won three in a row for the first time since July 11-17. The Padres (61-64) lost for just the fourth time in the last 11 outings.

Strasburg (8-6) won for the fourth time in five decisions and had his fourth strong outing in a row since coming off the disabled list earlier this month. He gave up only two hits and struck out seven with one walk and has allowed just four hits in his last 13 innings.

Span, who missed the previous 40 games with back problems, was finally at the leadoff spot again and he drew a nice ovation when he stepped to the plate in the first. Even though he was hitless in four official at-bats, he drew a walk and helped drive up the pitch count of San Diego starter and loser James Shields (9-6).

Shields left the game after his 121st pitch -- when second baseman Anthony Rendon hit a comebacker off his leg and reached on an infield single in the sixth.

Later in the inning, first baseman Zimmerman hit his grand slam to give Washington an 8-2 lead. It was the 10th homer of the season for Zimmerman, who like Span, also missed 40 games this year on the disabled list.

Shields gave up five runs and eight hits in 5 2/3 innings.

San Diego shortstop Jedd Gyorko hit a solo homer -- his second of the game and 10th of the year- in the seventh to cut the lead to 8-3 off reliever Casey Janssen. It was the third multi-homer game of his career and first this season as he drove in all three San Diego runs.

Padres interim manager Pat Murphy was ejected in the top of the seventh -- the fourth time he has been tossed this season.

Rendon, shortstop Ian Desmond and third baseman Yunel Escobar had two hits for the Nationals. Rendon and Escobar also scored twice.

San Diego first baseman Yonder Alonso had two hits.

Gyorko hit a two-run homer to left in the second off Strasburg to give San Diego a 2-0 lead.

Wilson Ramos, the Washington catcher, lined a two-run, two-out homer just over the fence down the left-field line to tie the game in the second.

Washington grabbed a 3-2 lead in the third off starter Shields. Rendon singled and Escobar got another two-out hit -- a double -- to drive in Rendon.

The Nationals built the margin to 4-2 in the fifth as Desmond had a two-out double to score right fielder Bryce Harper, who led off the frame with a double of his own.
