NEW YORK — The struggling New York Mets shuffled bullpen arms again Wednesday, replacing left-handers José Castillo and Richard Lovelady with a pair of pitchers called up from the minors.

Castillo and Lovelady were both designated for assignment. Right-hander Jonathan Pintaro was selected to the major league roster, and lefty Brandon Waddell was recalled from Triple-A Syracuse.

Pintaro, who was pitching for an independent team in Montana when the Mets signed him to a minor league deal in June 2024, is looking to make his major league debut. He had just been promoted from Double-A Binghamton to Triple-A Syracuse on Tuesday before getting re-routed to the big leagues.

Waddell has made four relief appearances for the Mets this season, compiling a 3.38 ERA in 10⅔ innings.
