Domingo Santana homered twice, and the Milwaukee Brewers beat Washington 7-2 Sunday to take three of four games from the Nationals.
Brewers starter Brent Suter, who had not pitched for the Milwaukee since Aug. 12 because of left rotator cuff inflammation, allowed two hits in three scoreless innings and left after 43 pitches.
Jeremy Jeffress (2-0), Jacob Barnes and Anthony Swarzak combined for five hitless innings before Junior Guerra gave up a two-run homer to Ryan Zimmerman in the ninth.
Without injured star Bryce Harper since mid-August, the Nationals stumbled a bit following a four-game winning streak against the New York Mets and Miami, scoring only eight runs in the four games against the Brewers. The only team in the NL East above .500, Washington (82-54) maintained a 15-game lead over the second-place Marlins.
Milwaukee began the day 1½ games behind Colorado for the NL's second wild card.
