Phillies catcher J.T. Realmuto lost his arbitration case against the Phillies today. That means he’ll get a $10 million salary in 2020. He had filed asking for $12.4 million.

That was Realmuto’s last time through the arbitration process, as he’s set to become a free agent after this season. There were reports back in November, however, about he and the Phillies discussing a long-term contract extension.

Most of the top free agents this offseason have already signed, a refreshing change after the last few stagnant winters. Now, with players reporting to spring training in just a few weeks, let’s turn our attention to the best players available on the open market after next season.

This list includes only unrestricted free agents, because we don’t know now if Giancarlo Stanton, J.D. Martinez or Dellin Betances will opt out of their current deals. The same is true with Anthony Rizzo, Carlos Santana and Corey Kluber, whose clubs have the option to keep them for another year.

Here are the top five free agents slated to hit the market next winter.

Any way you slice it, Phillies catcher J.T. Realmuto is headed for a historic contract in 2020.

Realmuto and the Phillies began the salary arbitration process with an exchange of proposals on Friday.

The Phillies filed at $10 million.

Realmuto’s camp came in at $12.4 million.
