Merryweather entered with two runners on and two outs and threw just two pitches to Aaron Hicks before Gary Sanchez was tagged out in a rundown between first and second base after a pitch in the dirt. He didn't return for the ninth.
Merryweather has two saves and has allowed just one hit and one walk with seven strikeouts over 4⅓ innings in four appearances. His fastball has reached 100.4 mph this season.
Also, Ross Stripling was scratched from his scheduled start Wednesday against the Yankees due to right forearm tightness. He was unable to get loose before the game.
T.J. Zeuch replaced Stripling.
Game notes: RHP David Phelps, hit in the lower back by Clint Frazier's 100.7 mph liner Tuesday night, is day-to-day with a bruised back. ... RHP Anthony Castro had his contract purchased from the alternate site and will work out of the bullpen.
