Carlos Marmol got off on the wrong foot in Thursday's Opening Day contest, giving up the winning run in a 2-1 loss to the Nationals. Marmol entered in the ninth inning of a tie game, retired the first two batters, and then surrendered a double and RBI single that turned out to be the game-winner. Coming off the worst season since his rookie campaign, Marmol could be a hit-or-miss closer all season.
