Problem is, you can't tell who is and isn't until you get them reliable strike zones called by major-league umps and hitters who can crush average pitches instead of fouling them off.
NPB pitchers come over into the AL, as Sasaki did, and they find out that the center of the plate is a huge "land mine" that didn't exist in their previous league. Even Felix took 2 full years to grasp that.
Then the question becomes, how well do their games work, take away their ability to score "gimme" strikes when behind in the count...
That is just a great capture of the problem, G. ... looks to me like Beavan's game works fine in the AL.
