MASHANTUCKET, Conn. -- In the not-too-distant future, the Red Sox will soon have a slew of their own star players eligible for free agency.

After 2019, Chris Sale, Rick Porcello, Xander Bogaerts, and, should he opt-out of his current deal, J.D. Martinez will be eligible. The following year, Mookie Betts and Jackie Bradley Jr. will be free agents.

So it's with some alarm that these players are, for the second straight winter, watching a market in which even the game's biggest stars are having difficulty attracting interest from teams.

If Manny Machado and Bryce Harper can't find their expected paydays and Martinez had to wait until the end of February to get an under-market deal, that doesn't bode well for others when it comes time for their turn at free agency.
