The 12th, is the deadline for teams and their arbitration-eligible players to file salary figures for 2018.
Because it is around this time of year that teams start getting serious about locking up their young players long-term.
Friday is not a hard deadline — teams and players can still work out a contract of any size after filing salary figures — but both sides like to get a deal wrapped up sooner rather than later.
In the coming days and weeks, more than a few of baseball’s best young players will put pen to paper and agree to a long-term extension with their current team.
It would seem unwise for the rebuilding White Sox to lock up Jose Abreu, a soon-to-be 31-year-old already limited to first base, but the club highly values his leadership and the example he sets for their younger players.
Abreu is starting from a much higher base salary because he originally signed with the White Sox as a free agent after defecting from Cuba.
