Cristian Guzman had three hits and three RBI, Hector Carrasco pitched six strong innings and the Nationals beat Florida 4-0 on Monday night to put the Marlins on the brink of playoff elimination.Florida has dropped four straight and 10 of 12. Another loss, or a Houston victory, will knock the Marlins out of NL wild-card contention.After the game, the Marlins announced they sent pitcher A.J. Burnett home for the remainder of the season. It came a day after Burnett, who can become a free agent after this season, complained that the coaching staff is too negative."In the best interest of the team, A.J. was advised to leave the team and he has done so," Marlins general manager Larry Beinfest said. "There will be no multiyear contract offer made to him."Carrasco (5-3), a former reliever making his fourth start this season, allowed two hits, three walks and struck out six. He has not given up a run in his past three starts, spanning 17 2/3 innings."I'm surprising myself," Carrasco said. "I'm surprised at the way I've been pitching. This is the first time in my whole career that I'm pitching the way I'm pitching now."Jason Vargas (5-5) was the tough-luck loser. He yielded one run and five hits in seven innings."You have to go out and play every day like it's your last game," said Vargas, 0-4 in his past seven starts. "You have to think of there being something still to play for, and that's what we're doing. Things just aren't going our way around here lately."Ryan Zimmerman's run-scoring single and Guzman's two-run double sparked a three-run eighth against Marlins reliever Antonio Alfonseca.The victory snapped a three-game skid and gave Washington its second win in nine games. The Nationals moved above .500 again at 79-78."They see the finish line and they don't want the season to slip away," Nationals manager Frank Robinson said. "They want to finish above .500. They have pride."Washington took 1-0 lead in the second. Nick Johnson led off with a triple to left, where the ball got past a diving Jeff Conine, and scored on Guzman's two-out single.Guzman, hitting .215 overall, is batting .338 (23-for-68) in his past 21 games."I want the season to start over right now, but it's almost over," he said.Jay Bergmann, Joey Eischen and Gary Majewski finished the five-hitter, Washington's ninth shutout this season.Nationals right fielder Jose Guillen left after being hit by a pitch in the third inning.
