Hultzen was non-tendered by the Cubs on Monday, Jordan Bastian of MLB.com reports.
Hultzen appeared in six games for the Cubs last season, all in September. He didn't allow a run over 3.1 innings of work, fanning five and walking two over that stretch. Given his limited big-league experience and past shoulder injuries, he may need to accept a minor-league deal to pitch in 2020.
