Mets 3, Nationals 1
Hernandez tossed seven crisp innings and the Mets beat the Washington Nationals 3-1 on Saturday in the opener of a day-night doubleheader.
"Not many guys can do what he does, throwing his breaking ball for strikes as consistently as he does," New York manager Willie Randolph said. "He never surprises me."
Ruben Gotay's RBI single in the seventh inning gave the Mets a 2-1 lead and made a winner out of Hernandez (7-4), who has won three straight decisions. New York has won 11 of El Duque's 17 starts this season.
"I feel good, I'm happy," Hernandez said. "My team lost yesterday [and] I helped a little bit today."
Aaron Heilman worked a perfect eighth for the Mets and Billy Wagner got three outs to finish off the three-hitter and earn his 24th save. It also was save No. 348, moving him past Randy Myers for seventh on the career list.
Hernandez cruised through the punchless Nationals, who were last in the majors in runs, home runs and RBIs entering the game. He struck out eight, walked two and allowed just three hits.
"When I have my curveball, my slider, it's very good," he said, "and my control was very good for me."
Jimenez's bloop single to center in the first was Washington's only hit until Lopez homered with one out in the sixth to tie it at 1. El Duque struck out four straight batters before Lopez drove a 1-1 pitch out to right for his sixth of the season.
"He comes at you in a lot of directions," Zimmerman said. "Once you face him you know what to expect but when he's getting ahead in the count like he was today it's still real tough."
El Duque retired the last five batters he faced and threw 62 strikes in his 99 pitches. He is 3-0 with a 1.13 ERA in his last six starts at Shea Stadium.
"He's got about 10 pitches from four different arm angles," Nationals manager Manny Acta said. "You know we just couldn't do anything with him."
The Mets broke through in the fourth against Redding, who retired 10 of the first 12 batters he faced. Delgado walked with one out and went to third on Ramon Castro's single to center.
"I made I thought only one bad pitch to Milledge and he was able to drive in a run there early in the game," said Redding, who equaled a career high with eight strikeouts. "I was able to throw both the curveball and slider for strikes and keep them off the fastball."
Milledge started in center field for fourth straight game with Carlos Beltran out because of a stomach muscle strain. Randolph said he isn't sure when the All-Star will be able to return.
