The Philadelphia Phillies placed closer Seranthony Dominguez on the 15-day injured list because of tendinitis in his right triceps. He is undergoing an MRI on Sunday.
Dominguez was held out of Saturday's doubleheader against the New York Mets after experiencing tightness in his right triceps in the morning and last pitched on Wednesday. The move was made retroactive to Thursday.
"I take it seriously," Dominguez said Saturday. "I have to take care of my arm. It's the only way I can compete.''
Dominguez, who has been an anchor at the back end of Philadelphia's bullpen, returned this season after an over two year recovery from elbow issues and Tommy John surgery.
