Thaiss, he has an upward mobility clause five days prior to Opening Day. Cotillo also notes that Thaiss would make a salary of $1.3MM if added to the roster.
When an upward mobility clause is triggered, a player is offered up to the other 29 clubs in the league. If any of them are willing to give the player a roster spot, then the signing club has to either give him a roster spot themselves or trade him to another club that will. If no club offers him a roster spot, then he can be sent to the minors as non-roster depth.
Today is 6 days until Opening Day.
