Here are the key 2019 MLB offseason dates, and how they impact the Mets...
Day after World Series ends: Free agency begins
The Mets should be returning most of the 86-win team that fell three games short of a playoff spot in 2019. However, they need massive improvements in the bullpen and will also likely need to find a starting pitcher to replace Zack Wheeler, who is expected to depart via free agency.
Among the biggest names expected to hit the free agent market: Gerrit Cole, Anthony Rendon, Marcell Ozuna, Dellin Betances, and Will Smith.
The Mets' notable free agents are Wheeler, Todd Frazier, and Juan Lagares (whose contract is expected to be bought out for $500,000).
