My impression in watching Huston pitch is that he has been well taught, probably by his dad, to focus completely on only those things you can control. I have watched Huston get some horrible ball/strike calls, and when he does, he goes through his exact same routine of catching the ball from Kendall, turning to his left and walking around the back of the mound, getting on the mound, getting the signal, and throwing another pitch. In other words, he doesn't lament the bad call, get all worked up about what might have been, etc. etc. He just completely focuses on the only thing he controls--his next pitch!
Sort of like the Serenity Prayer;
Grant me the serenity to accept the things I cannot change,
the courage to change the things I can,
and the wisdom to know the difference.
You can't change the last call. You can only change the next pitch that you throw!
Contrast this to Blanton tonight. Roaming around the mound, feeding on his anger and frustration, becoming moreso. If anything pissing off the umpire, rather than persuading him to become a better umpire, or whatever he thought he was doing. Mind you, I understand he was getting bad calls,,,,but the real question here is what do you do that most improves your situation. IMHO, it's Huston's approach, and not Joe's.
I remember reading that Ted Williams' had a fantastic eye at the plate. But he very rarely argued a call with the umpire (as opposed to arguing with the press and the public which he constantly did). The article said he just accepted that umpires were human. (and probably as a star he tended to get the benefit of the calls, so let's not get too carried away with this theory). But still, it's the result that counts,,,,and letting yourself get upset just doesn't help the result--it just puts you outside the zone.
Were I Macha, I would try to get this lesson deeply ingrained in all of my young pitchers. And the assignment for letting the umpire know your dissatisfaction with poor calls would be with my veteran catcher, Kendall in this case, and the coaches and the manager.
