Shortly after DC centerfielder Lastings Milledge injured his right groin when he slipped while retrieving a ball at the wall in center at Nationals Park last night, the Nationals announced that Milledge would be placed on the DL, and former Montreal Expos' undrafted free agent signing, Rogearvin "Roger" Bernadina, 24, out of Curacao, Netherlands, will make his Major League debut some time soon as he joins the Nationals roster all the way from Double-AA Harrisburg. MLB.com's Bill Ladson has the story in his article entitled, "Milledge leaves early with groin injury".
