ST. PETERSBURG, Fla.(AP) The Tampa Bay Rays gladly took a break.

Pinch hitter Willy Aybar got a lucky bounce, doubling off the third base bag in the eighth inning, and the Rays completed a sweep of the Washington Nationals with a 5-4 victory on Sunday.

''It's unusual to see that. I'll take it,'' manager Joe Maddon said after Tampa Bay's fifth straight win.

Carlos Pena opened the eighth with a double off Ron Villone (3-3). After Ben Zobrist struck out, Aybar hit a ball down the line that nicked the bag and angled away from third baseman Willie Harris into left field for the go-ahead hit.

''I think he would have made that play easy,'' Pena said. ''I had to freeze, then I saw the ball take a weird hop.''

Said Washington manager Manny Acta: ''I think what preceded that was more important than complaining about breaks.''

Gabe Kapler homered in his third straight game and drove in three runs for Tampa Bay. Dan Wheeler (2-1) worked a perfect eighth and J.P. Howell pitched the ninth for his third save.

''Collectively as a team, I want to us to enjoy the moment,'' Kapler said. ''It was an enjoyable day.''

The Rays' bullpen has not given up a run in its last 22 1-3 innings. Tampa Bay has 17 comeback wins this season, including all three games with Washington.

''When you've had a bit of success in the past, you kind of expect to win it somehow,'' Maddon said. ''That's helped us the past few days.

Alberto Gonzalez drove in three runs for the Nationals, who have lost 15 of 18. Washington has been swept in seven series this year.

''We win as a team and we lose as a team,'' Acta said. ''We haven't played the way we were expected to play. We're all accountable for what's going on.''

Tampa Bay, which was down 4-0, tied it at 4 on Kapler's two-run homer in the sixth.

Kapler had a tiebreaking, pinch-hit home run n the eighth inning of the Rays' 4-3 win Friday night. He didn't hit any homers in his first 34 games this season.

Gonzalez put the Nationals ahead 1-0 on an RBI single in the second. He hit a two-run double off James Shields in a three-run fourth that made it 4-0.

''It's just tough for us,'' Harris said. ''There's really no excuse for it. All you can do is go out there and put forth you best effort and see what happens. We're all trying.''

Tampa Bay got within 4-2 in the bottom of the fourth on Kapler's RBI single and a run-scoring sacrifice bunt by Dioner Navarro .

Shields gave up four runs and nine hits in 6 1-3 innings. Washington rookie Ross Detwiler allowed four runs, six hits and five walks over six innings.

The AL champion Rays are three games over .500 for the first time this year.

''You stink together through those tough times like we did early, you're going to have a little shine here,'' Howell said. ''We kind of see the light and know that if we keep going we're going to have a pretty good push here.''
