Baseball teams should be built to win. In which case, it’s only a small concern to see the New York Mets with a roster that includes only a small number of pitchers with minor league options.
Assuming everyone is healthy, the current crop of Mets relievers includes three guys with minor league options: Edwin Diaz, Seth Lugo, and Robert Gsellman.
The starting rotation does have three guys with minor league options left—Steven Matz, Marcus Stroman, and Noah Syndergaard. However, if any of them are demoted, the team is in bigger trouble than having some roster flexibility to promote a fresh arm to the big league roster.
