I’d think Vaz would be more likely than Wacha. My philosophy (which I assume teams use) is never offer a QO unless you’re prepared for the player to accept. With Vaz, not like the Sox have bountiful options ready to snag the catcher position for one year, and outside of Willson Contreras, free agency offers very little. One more season of Vazquez, even at a QO price, might not be so bad.
Wacha feels more replaceable to me.
And the Yankees might double burn themselves giving a QO to Taillon while letting Chapman walk…
