Nationals optioned LHP Mike Hinckley to Double-A Harrisburg and RHP Josh Karp to Triple-A New Orleans; reassigned RHP Dan Smith to minor league camp.
Hinckley struggled with his command in major league camp, and since the Nationals have seven potential starters still ahead of him, it’s less likely that he’ll arrive before the All-Star break. Smith, who is trying to work his way back from shoulder surgery, might get a look if he pitches well in Triple-A for a month or two.
