Kranick cleared waivers and was assigned outright to Triple-A Rochester on Sunday.
Kranick will remain in the Nationals organization to end the year after being designated for assignment Friday. The right-hander missed a couple months of the season following 2025 flexor tendon surgery and struggled to the tune of a 9.33 ERA and 2.18 WHIP in 17 appearances out of the Washington bullpen when healthy.
