Game 15 lineups: Nats at Marlins

MIAMI - Hello one last time from Marlins Park, where the roof actually is open as I type this. (Don't worry, it'll be closed up in time for first pitch at 1:10 p.m. Wouldn't want to play a ballgame in, you know, sunlight, would you?)

The Nationals and Marlins wrap up their four-game series, with the Nats looking to win three out of four and improve to a major league-best 12-3. They'll have Max Scherzer on the mound, looking to improve to 3-0 in his first start of the season against Miami. Yusmeiro Petit obviously won't be available after his four-inning relief stint last night, but everybody else in the bullpen should be good to go.

Not that you shouldn't always keep an eye on Bryce Harper, but today would be an especially good day to do that. Because he's facing Tom Koehler, against whom he has homered five times in his career. And because Scherzer's starting for the Nats, and you know how well Harper seems to do at the plate when Scherzer is on the mound.

As expected, Jayson Werth is not in the lineup after leaving last night's game with a tight left hamstring (though he was going to be off today regardless). Ryan Zimmerman is also getting the day off.
