Cotts was reassigned to the Nationals' minor-league camp Wednesday, MLB.com's Jamal Collier reports.
Cotts was a useful bullpen piece for the Brewers and Twins in 2015, but after failing to find much success while pitching exclusively at the Triple-A level last season, he was forced to settle for a minor-league deal with the Nats in the offseason. While he threw respectably in spring training, Cotts didn't shine nearly enough for the Nationals to justify opening up a 40-man roster spot for him. Assuming he decides to stick with the organization, Cotts figures to open the campaign with Triple-A Syracuse.
