Manaea, who turns 33 on Feb. 1, had signed two-year deals in each of the previous two offseasons, first a $25 million agreement with San Francisco and then a $28 million deal with the Mets. He opted out each time after one season to become a free agent again.

Sean Manaea signed a one-year prove-it contract with the Mets. He proved that he was still capable of fulfilling the promise of becoming a solid front-end rotation option, parlaying a career year into a longer deal with the team that he thrived on last year.
