MIAMI -AP- Max Scherzer strengthened his case for the NL Cy Young Award.Scherzer pitched 6 2/3 innings to tie for the National League victory lead with 18, helping the Washington Nationals beat the Miami Marlins 8-3 on Wednesday night."When we needed shut-down innings I was able to go out there and put up zeroes when we really needed it and it helped get the offense going," Scherzer said.Scherzer (18-7) allowed three runs and struck out eight to push his major league-leading total to 267. He's tied for with Chicago's Jon Lester for the most wins in the NL. "He should be in strong consideration for a Cy Young," Nationals manager Dusty Baker said. "I talked to him earlier and I gave him a number and said let's win six or seven of them and he said, `I want to win all of them.' That's the attitude you want and that's the attitude that he carries and the guys love playing behind him."Ryan Zimmerman hit a three-run homer and Trea Turner also homered for the Nationals."We got some good offensive days out of some guys especially after our offense was a little sleepy the last couple of days," Baker said.Washington ended a four-game losing streak and lowered their magic number to two to win the NL East over the New York Mets with a chance to clinch on Friday at Pittsburgh."I've never been a part of anything like this, but it's exciting," Turner said. "Every game means something even down the stretch playing for home-field advantage or whatever it may be. It's exciting and I enjoy it."Tom Koehler (9-12) allowed four runs -- three earned -- in four innings for the Marlins. They had won three in a row to stay in contention for the second wild card spot."It kind of leaves us in the same spot," Marlins manager Don Mattingly said. "It would've been nice if we could have won and cut a game off. Hopefully the Dodgers win tonight."Christian Yelich hit a solo home run and Derek Dietrich hit a two-run homer to chase Scherzer in the seventh and cut it to 6-3.Prior to the home runs allowed by Yelich and Dietrich, Scherzer had only allowed two hits."Obviously there in the seventh-of course I'm frustrated about that," Scherzer said. "You can't walk away from an outing like that feeling great when you give up two home runs especially when your last pitch is a home run. But you'll beat yourself up and drive yourself crazy if you try to sit here every single start worrying about the negatives. This start had way more positives and that's what I'm going to focus on."Wilson Ramos had an RBI double and scored on a sacrifice fly in the eighth to extend the Nationals' lead to 8-3.Washington scored its first run when Koehler's pick-off throw to second went into centerfield and Yelich was unable to field it cleanly allowingDanny Espinosa to score.Zimmerman's three-run homer, his 15th, to left field gave the Nationals a 4-0 lead in the fourth."You can't really afford to spot Max a 4-0 lead," Koehler said. "More times than not he gets four runs, he's not going to give it back."Jayson Werth had an RBI single and Turner hit his 12th home run for a 6-0 advantage.
