The Mets may have roughly $40 million to spend this winter, John Harper of the NY Daily News recently reported.
3B Todd Frazier, who is a free agent after spending the end of the 2017 season with the Yankees, would be a wise signing for the Mets, according to MetsBlog's Matthew Cerrone.
RHP Yu Darvish is also a free agent, and the Mets signing him would signal that they're all-in for 2018, says MetsBlog's Maggie Wiggin.
The Mets have needs at third base, in the starting rotation, in the bullpen, and potentially in center field.
