Heller (biceps) was released by the Yankees on Friday.
Heller was designated for assignment Wednesday and will now have to try his luck with a new team. It's unclear whether or not the biceps nerve issue that ended his 2020 campaign prematurely affected the Yankees' decision to let him go, but that could certainly scare off teams who might otherwise be interested in his 2.59 ERA in 31.1 innings at the major-league level.
