The Mets have released Kiko Calero, tweets Newsday's David Lennon. The club had signed Calero to a minor league deal in March, after the right-hander received a somewhat unexpected lack of interest for most of the offseason.
Calero posted a 1.95 ERA in 67 relief appearances for the Marlins in 2009, but health was a concern for the 35-year-old heading into this year. He failed to crack the Mets' big league roster and has spent the season pitching for Triple-A Buffalo. In ten appearances for the Bisons, Calero pitched 17 innings and recorded a 10.59 ERA.
