Game 112 lineups: Nats vs. Braves (Holland signed)

Who's ready for a long - and important - day and night of baseball? The Nationals better hope they are. They enter the day 5 1/2 games behind the Phillies, four games behind the Braves. By night's end, they could be anywhere from four to seven games behind Philadelphia, two to six games behind Atlanta. So, yeah, it's a big day.

It all gets started with the opener of this day-night doubleheader, with Jefry Rodriguez taking the mound for the Nats. It'll be the right-hander's sixth career major league appearance, his fourth career start. And they're going to need him to be effective and at least give them five innings so as not to overtax the bullpen before they ever get to the nightcap.

Speaking of the bullpen, there's a new arm down there: Greg Holland. Yes, the Nationals have officially signed the veteran right-hander to a major league contract, and Holland is here and available to pitch both games today. What can they expect from a guy who last pitched July 21 for the Cardinals and then was dumped with his ERA at 7.92? We'll see.

Holland replaces Jimmy Cordero, who has been optioned to Triple-A Syracuse. Rodriguez officially is the 26th man for the doubleheader, so he'll be sent back down after the game with no other transactions necessary.
