The Mets are expected to place right-handed reliever Drew Smith on the injured list tomorrow, retroactive to Monday, according to reporting from Tim Britton and Ken Rosenthal in The Athletic. The nature of the injury is unclear and is currently being referred to as an “unspecified arm issue.” Smith did not pitch in either of the two games against the Yankees and Buck Showalter indicated that his bullpen options were limited in last night’s game. After a strong start to the season, the oft-injured Smith has struggled since mid-May and has nearly matched his career high in innings pitched in a season at the major league level.
