The Nationals haven't officially named a closer, but manager Jim Riggleman appears to have found his man in Drew Storen. Storen pitched a scoreless ninth inning on Sunday against the Giants to notch his fifth save of the young season. Washington has a total of eight saves as a team. "What I would really like to do is see how the whole thing unfolds," Riggleman said when asked about Storen. "A lot is going to depend on who's coming up and all that, the lead that you have, the margin that you have. That changes things a little bit. "I think everybody in the community wants Drew to be the closer. And I want that. But he's 23 years-old, and I don't want him to run out there four days in a row or three days in a row. I want to preserve him a little bit. So I always have to have the option of (Tyler) Clippard and Burnett doing that. The more comfortable I get that we're going to turn it over to Drew, then it gives me the option to use Burnie earlier in the game, like the seventh." Storen has a 0.60 ERA and 11 strikeouts in 15 innings this season.
