Zimmerman’s streak of safely reaching base ended at 43 games. He went 0 for 4 and struck out twice, falling three games short of the franchise record set by Rusty Staub for Montreal from 1969-70.

No Mets starter had even reached the eighth inning this year, and Hernandez delivered on a drizzly night when New York trotted out a depleted lineup. The Mets put All-Star shortstop Jose Reyes and outfielder Ryan Church on the disabled list before the game, and plan to hold out Carlos Beltran until the weekend because of a bruise below his knee.

Highly touted Fernando Martinez got an RBI in his major league debut and Gary Sheffield hit a three-run homer in the seventh inning to break it open. A day after umpires looked at replays to verify he’d homered, Sheffield left no doubt with the 504th of his career.

On his first pitch after giving up the homer, reliever Jason Bergmann threw a pitch over Fernando Tatis’ head. Plate umpire Dan Iassogna warned the teams against further beanballs, and Nationals manager Manny Acta came out to discuss it.

Tatis was nicked in the left shoulder later in that at-bat and calmly took first base. Hernandez plunked pinch-hitter Justin Maxwell in the leg in the eighth, and there were no problems.

The Mets backed Hernandez with three double plays, and catcher Omir Santos won a synchronized diving match with Josh Bard to tag him out at the plate.

Hernandez, listed as 34 years old, walked one, struck out six and threw 127 pitches. He won with a familiar formula — pitching in and out of trouble. Opponents came into the game batting .307 against him, and the Nationals hit him, too.

Adam Dunn singled for his 1,000th hit, then cracked his 15th home run in the seventh. His drive to left was only the second opposite-field shot in 22 games at Citi Field.
