The New York Mets sent right-hander Kodai Senga to Triple-A Syracuse on Friday after a difficult stretch on the mound.
Senga has not pitched six full innings since June 6 and holds a 6.56 ERA over his past eight starts. Earlier this year, he also missed more than a month with a strained hamstring.
In corresponding moves, the Mets reinstated catcher Francisco Alvarez from the injured list and added reliever Wander Suero, who was claimed off waivers from Atlanta Braves on Thursday.
Alvarez had been sidelined since spraining a ligament in his right thumb in July. His rehab was further delayed when he fractured his left pinkie finger after being hit by a pitch while playing for Syracuse. Though Alvarez’s thumb injury will eventually require surgery, the Mets hope he can delay the operation until after the season.Â
To make room for Alvarez, the club optioned catcher Hayden Senger to Syracuse along with Senga.
