One reason Gonzalez may still be unsigned could be because he’s looking for a multi-year MLB deal. The Mets may not be willing to offer him a major league deal due to the fact they already have a set rotation, and Jason Vargas pitched much better over the second half of the 2018 season, posting a 3.81 ERA. over that stretch.
While Gonzalez would be a great fit for the Mets on a minor league deal, he’s currently the second-best pitcher available on the free agent market, behind only Dallas Keuchel. Unless general manager Brodie Van Wagenen surprises the fan base again by signing Keuchel, Gonzalez should be their man at this point.
Gonzalez has an ERA under 2 lifetime (in 17 starts) at Citi Field. If that’s not enough to sign him, I don’t know what is.
