The Mets signed Kiko Calero to a minor league deal worth up to $1.5MM. He earns $850K if he makes the team, with another $650K available in incentives. There is no opt-out if the Mets send him to the minors.
Calero had been looking for a major league deal, so the Mets deserve credit for adding him on a minor league contract, especially since there's a good chance Kelvim Escobar will start the season injured.
The 35-year-old pitched 60 innings of 1.95 ERA ball last year for the Marlins, with 10.4 K/9 and 4.5 BB/9. But the Marlins had concerns about his health and they weren't the only ones. Peter Abraham of the Boston Globe heard from two executives who said Calero's medicals didn't look good (Twitter link). That didn't prevent eight teams from offering the righty minor league deals, according to MLB.com's Alden Gonzalez (via Twitter).
