It's a $9.5-million raise for the 26-year-old outfielder, who earned $10.5 million last season.
His efforts paid off in a big way, as Betts is now coming darn close to doubling his salary for the upcoming 2019 season.
According to Chris Cotillo of MassLive, the Sox once again plan to employ a "file-and-trial" approach this offseason, meaning they will take any player who they can not come to an agreement with to an arbitration hearing. His almost $10 million jump is the highest arbitration raise ever received by a position player.
Nevertheless, this just goes to show that if the Red Sox hope to keep Betts in Boston for the foreseeable future - as most fans are hoping - they are going to have to break open the bank vault and shower him in dollar signs. For now, let's take a look at each of the deals we know about, how they compare to the projections forecast by MLB Trade Rumors, and what this means for their role with the team heading into next season. The salary figure is a record for a player in his second year of arbitration eligibility.
