The Marlins lost all of a three-run lead after a lengthy stoppage and pinch-hitter Corey Brown singled to drive in Ian Desmond with the winning run in the bottom of the 10th, lifting the Washington Nationals to a 7-6 victory Saturday.

Adam LaRoche singled off Chad Gaudin (3-2) to open the inning. Desmond singled him to third and Danny Espinosa was intentionally walked to load the bases. With the infield in, Kurt Suzuki grounded into a fielder's choice as LaRoche was thrown out at home, but Brown followed with a bloop single to right.

Leading 6-3 entering the eighth, Miami's bullpen took over for starter Mark Buehrle and surrendered two runs in the inning. Following a 2-hour, 33-minute rain delay which began in the middle of the ninth, Jayson Werth led off the bottom of the inning with a home run off Heath Bell to tie it at 6-all.

"It gets frustrating, embarrassing, tired losing games day in and day out the way we lose games," Guillen said. "We battle back all day, wait for hours, lose a game like that. ... You feel like you're wasting a day of your life at the ballpark, getting paid for it.

"But what I see is the same (thing) I see all year long, blown games. That's the bottom line."

Miami's relievers lost a four-run lead on Friday and nearly coughed up a three-run cushion in the 10th before winning.

Drew Storen (2-1) pitched a scoreless 10th inning for the win Saturday.

A.J. Ramos gave up a two-run homer to Ryan Zimmerman with no outs in the eighth, trimming the Miami lead to 6-5. Michael Morse and LaRoche followed with singles.

Ryan Webb came in and got Desmond to ground into a fielders' choice, putting runners on first and third. Desmond stole second, but Webb struck out Espinosa looking and after intentionally walking Chad Tracy, he struck out pinch-hitter Roger Bernadina to end the inning.

Bell warmed up for the ninth before a fierce storm system rolled through the Capital area. Then he and the others involved waited and waited.

"Just a long time before I went into the game," said Bell, who did not throw again until returning to the mound for his warmup pitches.

Eight real pitches later and in front of dozens of remaining fans, Werth drilled a 3-2 fastball deep over the wall in left-center.

"I don't think (the delay) had any fathom on what happened," said Bell, who eventually struck out the side after blowing his seventh save opportunity in 26 attempts this year. "It's been my year. I don't have any luck this year, plain and simple."

For the second straight day, the Marlins tagged Washington's starter early.

Gorkys Hernandez led off with a homer to left-center off Ross Detwiler and two outs later Giancarlo Stanton homered for the second straight day. It was Stanton's 32nd homer and 10th in 19 career games at Nationals Park.

Donovan Solano made it 3-0 when he singled home Donnie Murphy in the second.

After Washington scored runs in the third and fourth, Miami scored two unearned runs against Detwiler in the fifth. Solano led off with a walk and, with two outs, Carlos Lee walked. When LaRoche was unable to come up with Justin Rodriguez's sharp grounder at first, Solano scored on the error and Lee went to third. John Buck's single scored Lee.

Detwiler gave up five runs, three earned, in five innings.

The Marlins added a run in the seventh as Solano doubled and scored on Zimmerman's throwing error on Ruggiano's grounder.

Buehrle allowed three runs and five hits, including two home runs in seven innings, and struck out five.

"That's part of the game, that's why you try to go deep," said Buehrle, who has pitched at least seven innings in half of his 28 starts this season. "We had a long rain delay, guess it works both sides. Guys are just sitting in the clubhouse, waiting to figure out what's going on. It's frustrating."

The Marlins scored five runs in three innings against Stephen Strasburg in Friday's extra-inning win.

Before Saturday's game, Nationals manager Davey Johnson announced Strasburg's season was over.

Strasburg finishes 15-6 with a 3.16 ERA in his first full season following elbow-ligament replacement surgery on Sept. 3, 2010. He struck out 197 in 159 1-3 innings.
