Saturday's game between the Brewers and Nationals was postponed by rain, setting up a double-header on Sunday. Washington's Jason Marquis, who has pitched well in two starts this season, is feeling better following elbow surgery last May. "He's feeling better. He had some things he was pitching through early last year, and he just got to the point where he said, 'I've got to get this checked out' -- and he did," Nationals manager Jim Riggleman said. "They removed some loose bodies after that in the elbow and he pitched pretty well after that." Marquis will pitch in the first game on Sunday against Yovani Gallardo. Milwaukee's Marco Estrada and Washington's Livan Hernandez are slated for the second game.
