The predicament screamed for a hero.

"The only way we can get out of this thing is somebody needs to step up and say it's over and done with," manager Mike Redmond said after the Marlins' losing streak reached eight on Monday.

Who better than the man who might as well wear a giant S on his chest? Giancarlo Stanton wasted no time, slamming a Stephen Strasburg changeup more than 420 feet to center field for a three-run home run in the first inning Tuesday at Marlins Park.

With Stanton tying a career high with five RBI and Tom Koehler (2-1) holding Washington to one hit for seven innings, the losing streak is over and done.

They had plenty of help in a resounding 11-2 rout of the Nationals and nemesis Strasburg, who has more wins against Miami (seven) than any other team.

"You saw an entire team step up. Tommy Koehler set the tone, did a great job. You have a tough lineup to plow through and I think he did a great job. It was great to see our offense strike early," Redmond said.

After being mauled in their first four meetings, it took an aggressive response to break the Nationals' stronghold.

That included a bench-clearing staredown after Washington's Ian Desmond took exception to a fastball under his chin from Koehler. Desmond and catcher Jarrod Saltalamacchia went jaw to jaw, and both teams converged on home plate, but no punches were thrown.

"Guys tend to get a little upset when they get crowded. But at the same time, they're attacking fastballs out over the plate," Koehler said. "We've been beat too many times late in the game over these last couple series and that's because we haven't established in."

This night the Marlins let their bats do the talking in a 15-hit onslaught.
