Single-A Potomac Nationals shortstop Rick Hague is done for the season with a shoulder injury suffered in early April. Hague has been attempting to rehabilitate the shoulder for two months in extended spring training. Hague told Will Flemming on P-Nats' radio that the shoulder "keeps popping out," so he will have surgery today. The former Rice University standout played two seasons alongside Nationals first-round selection Anthony Rendon. Hague batted .357 in four games, going 5-for-14 with two doubles, a homer and four RBIs before injuring his shoulder on a slide into second base April 13.
