SAN ANTONIO – Right-handed Phil Maton became a free agent on Monday after New York Mets declined its $7,775,000 option in favor of a $250,000 buyout.

The 31-year-old was 2-1 with a 2.51 ERA in his first season with New York, who acquired him from Tampa Bay on July 9. Maton was 3-3 with a 3.66 ERA in a career-high 71 total games and had a salary of $6.25 million.

New York also announced a left-hander Sean Manaea declined his $13.5 million option to become a free agent for the third straight offseason. Manaea agreed to a contract in January that included a $14.5 million salary for 2024, and the 32-year-old went 12-6 with a 3.47 ERA in 32 starts, striking out 184 and walking 63 in 181 innings.

After giving up his arm midseason, he became the Mets’ most effective starting pitcher and went 6-2 with a 3.09 ERA.
