Just two batters into his first start of the season, Ross Detwiler was in trouble. The Mets had runners on first and third with no outs. Detwiler struck out Daniel Murphy, got Jason Bay to pop up and struck out Lucas Duda. After that, the left-hander allowed only a walk and retired his final 13 batters to lead the Washington Nationals over the Mets 6-2 on Tuesday night and send New York to its first loss of the season.
