The Yankees designated Topa for assignment Saturday.
Topa gave up one unearned run in two innings during his lone appearance with the Yankees, and he'll now cede his spot on the active roster to Max Fried (elbow), who returned from the injured list Saturday. Topa is likely to clear waivers after posting a 7.29 ERA and 1.95 WHIP in 21 major-league innings this season.
