Palmquist will serve as the Nationals' opening pitcher for Friday's game against the Diamondbacks, Kyle Williams of TheBanner.com reports.
Analysis:Palmquist gave up four earned runs in 1.2 innings the last time he served as an opener Tuesday against the Rockies, but the Nationals will give him another chance to handle the opening frame or two during Friday's contest. Zack Littell is in line to pitch in bulk relief once Palmquist exits the game.
