I can't follow the logic here.

I still think Girardi got a raw deal simply because Cashman didn't like him:

"Essentially the Yankees felt Sanchez performed better behind the plate when first called to the majors in 2016, in no small part because he had been drilled regularly in the minors by former organizational catching instructor Josh Paul, especially in blocking balls in the dirt.

Paul used a pitching machine to pump high-velocity fastballs, as well as breaking balls, in the dirt at Sanchez, and the Yankees believe it made a difference in what is the young catcher's biggest weakness.

However, sources say that Sanchez grew tired of doing the drills and expressed that to Girardi going into last season. The manager, perhaps wanting to keep his young catcher happy or simply avoid a conflict, told him he didn't have to do all the extra work.

That may that led to more problems with passed balls, as Sanchez's total of 16 was the highest the American League."

Sanchez's defense is a problem. Practice and effort would help. If Boone can get Sanchez to resume these drills, I'd be pleasantly surprised.

But ... this is seriously the reason why Girardi is no longer the Yankees' manager?

Practice?
