The Cubs made a roster move Saturday morning, designating catcher Tucker Barnhart for assignment and recalling Miles Mastrobuoni to Chicago. This signals another move to fill the vacated 40-man spot, possibly for pitching reinforcements now that Marcus Stroman may miss another month or more and the Cubs have a few relievers who should be ready to come off the 60-day IL soon.
Brad Boxberger and Nick Burdi could be options for the bullpen in the near future, plus Brandon Hughes is feeling better and Ethan Roberts is ramping back up.
