The Mets wasted a sterling performance by Mike Pelfrey (on the day the organization's Sterling awards were announced), losing to the Nationals by a score of 2-0.Pelfrey (7-12) went 7 innings, allowing 2 runs on 6 hits, walking 2 and striking out 6.  The 2 runs were unearned, a result of David Wright's 17th error of the year, his 14th since returning from the disabled list.Wright bobbled a ground ball in the third inning off the bat of Ian Desmond, allowing the Nats' shortstop to reach base.  One batter later, Ryan Zimmerman walked.  Michael Morse and Jayson Werth followed with back-to-back singles to give the Nationals a 2-0 lead.Brad Peacock (1-0) earned his first Major League win, throwing 94 pitches in 5 innings, combining with the Nationals' bullpen for the shutout.  He kept the Mets off balance despite walking more (3) than he struck out (2).  Rick Ankiel helped nail the game down with a spectacular diving catch to rob Jose Reyes of an opposite-field extra base hit with 2 men on in the ninth.  Since choking against the Mets as a pitcher for the Cardinals in the 2000 playoffs, Ankiel has come up big on multiple occasions against New York as an outfielder.The Mets offense remained anemic against Washington pitching.  They were shut out tonight after scoring only 2 runs in each of the last two games.  Pelfrey, after struggling most of the season, has pitched better of late, allowing no more than 4 earned runs in each of his last 10 outings.  Tonight, he allowed no earned runs.  But shoddy defense and a lack of offense cost Pelfrey and the Mets tonight.In other newsJohan Santana decided to skip his rehab start for the Savannah Sand Gnats, realizing it would not be a good idea to over exert himself in a playoff environment, even if it is in A-ball.  So it looks like Santana will set his sights on Spring Training 2012.  Besides, Johan knows better than to mess with Sand Gnats.Also, The Mets announced today that AAA Buffalo's Josh Satin is the organization's minor league player of the year, and A St. Lucie's Darin Gorski is the organization's pitcher of the year.
