Rosscup was released by the Rockies on Wednesday, Baseball America reports.
The veteran southpaw joined the Rox on a minor-league deal in late January but wasn't included in the team's 60-man roster pool, so he was released. Rosscup split 2019 between the Dodgers, Mariners and Blue Jay while posting a 5.00 ERA, 2.28 WHIP and 26:19 K:BB over 18 innings.
