What's that?  Nationals Park sold out?  For who?Some guy made his major league debut in Washington, DC tonight.   Apparently he did pretty well.   New York Mets starter Mike Pelfrey did alright himself, becoming the first Mets starter to throw 9 innings this season, allowing just 1 run on 5 hits and no walks, while striking out 6.   But San Diego Padres starter Clayton Richard was also quite good, allowing just 1 run over 7 innings.   Neither was around when Ike Davis clobbered an Edward Mujica (2-1) pitch deep into the Queens night for a solo home run in the bottom of the 11th, leading the Mets to a 2-1 win over the Padres and making a winner of relief pitcher Elmer Dessens (1-1).The Nats have sold how few tickets for tomorrow?The Padres took a 1-0 lead in the 1st inning when Adrian Gonzalez doubled off the wall in left driving in Chase Headley.   Jose Reyes tied the game in the bottom of the 7th with his first right handed, and second overall, home run of the season.   It stayed that way until Davis sent the Mets fans home to go watch highlights from that other game.Santana tomorrow!
