The Mets have recalled RH reliever Gerson Bautista from Double-A Binghamton and optioned RH reliever Hansel Robles to Triple-A Las Vegas, it was announced Tuesday.
Bautista will wear No. 46 and be available for Tuesday night's game against the Nationals at Citi Field. Bautista's first appearance will be his big league debut.
The 22-year-old Bautista, who was acquired from the Red Sox last season as part of the Addison Reed trade -- has thrown 5.0 scoreless innings while allowing two hits, walking none, and striking out 11 in three games this season for Double-A.
