I Was Wondering about that Too...

I'm just passing this along without comment from a recent Baseball Prospectus chat with Kevin Goldstein (password required):

oira61 (San Francisco): Hi Kevin, I still don't understand how Alvarez agreeing to a new contract ends the grievance. The grievance was about passing the deadline; this is a more than a month after the deadline. Couldn't Aaron Crow and/or the Nationals now file a grievance?

Kevin Goldstein: Crow and the Nationals maybe could do something, but there's a HUGE difference here. Both the Nationals and Crow agree that their player is unsigned. In the Alvarez case, the Pirates said they had a deal, and the Alvarez side did not. HUGE difference.
