Nationals starter Ross Detwiler will get the call Tuesday in Game 1 against the Philadelphia Phillies. Rookie Tommy Milone will be handed the ball for Game 2 that night. The other prized recent call up, Brad Peacock, gets the nod Wednesday night at Philadelphia.
Also, Nationals reliever Ryan Mattheus participated in a simulation game Saturday in which he threw 20 to 25 pitches and faced two batters.
"It went well, the arm felt great," Mattheus confirmed.
Mattheus is recovering from shoulder soreness that has kept him off the active roster since August 25.
Mattheus said he felt like the velocity was there. "I talked to (the hitter) Steve Lombardozzi and he said it was coming out well. It is tough to tell. It feels strong."
He hopes to be in a game in a couple of days. Manager Davey Johnson said he will take it slow and may hold Mattheus out a little longer just to err on the side of caution.
