Mets retiring Carlos Beltran’s number after Baseball Hall of Fame election

PORT ST. LUCIE — Carlos Beltrán’s number is headed to the proverbial rafters at Citi Field.

The Hall of Fame outfielder will have his No. 15 retired this season during a ceremony, on a date still to be announced by the club, The Post has learned. Beltrán will also be inducted into the club’s Hall of Fame on that day.

The Mets originally planned a club Hall of Fame induction that included Beltrán, Lee Mazzilli and Bobby Valentine. Mazzilli and Valentine will have their induction ceremony May 30, the Mets announced Thursday. The change to give Beltrán his own day was decided after he was voted into the Hall of Fame by the Baseball Writers’ Association of America in January.

Beltrán announced last month that he would wear a Mets cap on his Hall of Fame plaque. Seaver and Piazza are the only other Hall of Famers with that designation. Beltrán also spent a significant portion of his career with the Royals, the organization in which he arrived to the major leagues.
