Yankees reliever Luke Weaver has been placed on the 15-day injured list with a strained left hamstring sustained while warming up at Dodger Stadium last weekend, an injury that moves Devin Williams back into the closer role. New York made six roster moves before a series opener against Cleveland, also activating infielder Jazz Chisholm Jr. and right-hander Fernando Cruz from the injured list, recalling right-hander Yerry de los Santos from Triple-A Scranton/Wilkes-Barre, optioning infielder Jorbit Vivas to the RailRiders and designating right-hander Carlos Carrasco for assignment.
