MIAMI -- The Washington Nationals headed home for the final series of the season guaranteed of at least a .500 record.
Preston Wilson homered and had five RBI and Nick Johnson added a home run and four RBI to help the Nationals beat the Florida Marlins 11-7 on Wednesday night and sweep the three-game series.
"They did not want a lot of the good things that they have done this year slip away," said Washington manager Frank Robinson, whose team had a share of first place in the NL East as late as July 25.
"They were on a mission. They had the mind-set to come in here and win three ballgames - it was probably the first time in the year we were thinking about sweeping a series before we played the first game. And we got it done."
Miguel Cabrera had three hits, including his 33rd homer, and four RBI for the Marlins, who lost their season-high sixth straight, eighth of nine and 12th in 14. Rookie Jeremy Hermida also had three hits, including his second home run.
Esteban Loaiza (12-10) allowed six runs and 10 hits in six innings. His streak of 33 2/3 innings without issuing a walk -- covering five starts -- ended with a base on balls to Cabrera with two outs in the fifth.
"We have four more days together as a team," Loaiza said, "and then I'll be sitting at home looking at the playoff games - and we should be there."
Brian Moehler (6-12) allowed seven runs and six hits in 3 1/3 innings. He has lost six straight decisions and hasn't won since July 20.
"I think over the last part of the year he wasn't as sharp; he may have been tired," Marlins manager Jack McKeon said of Moehler. "Most of the time he has pretty good control. He has shown that he can be a good fifth starter."
The victory left Washington at 81-78 and enabled the team to reach 40 road wins for the seventh time in the franchise's 37 seasons. Washington will host Philadelphia this weekend.
"I guess it was important to finish .500 or better, but we still came up short (of the playoffs)," Johnson said. "That's disappointing."
The Montreal Expos, who became the Nationals, finished above .500 only twice in the last eight seasons.
Eleven Nationals batted in a seven-run fourth that built a 9-2 lead. Marlon Byrd's run-scoring double, Gary Bennett's RBI single, Johnson's two-run single and Wilson's three-run homer accounted for the runs.
Every National in the starting lineup except the pitcher scored at least once. Wilson, Johnson and Jamey Carroll each had three of Washington's 15 hits, with Wilson and Johnson each falling a triple shy of the cycle.
"You don't get too many chances at a cycle, so it's definitely something that you think about," Wilson said.
Cabrera had a run-scoring single in the first, a two-run single in the third and a leadoff homer in the seventh.
Pinch-hitter Lenny Harris and Chris Aguila had RBI singles in the sixth for Florida.
