Rumbelow (elbow) was designated for assignment by the Yankees on Friday.
The right-hander was injured in his first appearance with Triple-A Scranton/Wilkes-Barre in 2016 and underwent Tommy John surgery shortly thereafter. He presumably won't be ready for the start of 2017, but Rumbelow gave the Yankees some useful innings in 2015 (4.02 ERA, 1.34 WHIP) and should land on his feet.
