The Yankees designated Tonkin for assignment Sunday.
For the fourth time this season, Tonkin has now been removed from an organization's 40-man roster, after the Mets (twice) and Twins previously designated him for assignment. The Yankees claimed Tonkin off waivers from the Mets in April, and he had generally pitched well during his time in The Bronx, logging a 3.37 ERA, 1.16 WHIP and 57:21 K:BB in 56 innings. However, with the Yankees in need of a fresh relief arm for Sunday's series finale with the Rockies, Tonkin ended up being the odd man out to make room on the roster for Phil Bickford, whose contract was selected from Triple-A Scranton/Wilkes-Barre. Given his strong body of work out of the New York bullpen, Tonkin stands a good chance of being claimed off waivers by another team.
