Haren threw six scoreless innings tonight, allowing just a hit and a walk and striking out eight, and Ryan Zimmerman's solo homer and Anthony Rendon's two-run double were enough to give the Nats a 3-0 win over the Mets.
The victory makes Haren 9-13 on the season and gives him two more wins than Stephen Strasburg. Baseball can be a funny game at times.
The Nats are now 22-9 in their last 31 games.
They've outscored the Mets 18-3 in the first three games of this four-game series, and have notched two shutouts.
Gio Gonzalez got the job done all by himself Monday night. Haren got it started tonight, and a quartet of Nats relievers pitched in (pun intended) to close out the win.
The Nats had been in danger of falling seven games behind the Reds in the wild card chase, but this victory keeps them six back of Cincinnati with 17 games now left on the schedule.
