Adding a wrinkle to a pitcher's delivery is a lot like giving a kid a new toy. He wants to play with it all the time, his TV friends don't want to talk about anything else, and whoever gave it to him is sure he's going to break it in a matter of minutes.
Brandon Morrow, as you're well aware, dropped his arm slot a few starts ago and now everything is sweet naked nectar. Nothing but strikeouts, ground balls, and the occasional half-dozen walk outing. Which stands in stark contrast to his swap partner and namesake — Morrow's results are quite positive. Is there anything to this lower arm slot? Does it help him throw strikes? Is it even real? The nerdmachine will tell us all the answers.
It's safe to say that, yes; Brandon Morrow dropped his arm slot. He's no Quisenberry, but he moved it down and out. I know the release point numbers pitch f/x spits out aren't super reliable from one park to the next, but trust me when I say I looked at outings from Rogers Centre only and they checked out.
But the movement's the thing, right? I know I saw Brandon Morrow toss some filthy tailing fastballs Friday night, really fooling hitters who gave up on fastballs that looked to be headed directly for their front hip. Is that new or just newsworthy because he threw them for strikes?

Dramatic as some of those changes are, they come with some provisos. I ignored vertical break for no good reason. I used the pitch classifications as they came - save one exception. I treated all Morrow's change ups as sinking fastballs. Surely some of these pitches are indeed changes while others are straight up fastballs masquerading as funkier stuff, but I don't have all night here.
The important takeaway here is how much more Bruce Walton has Brandon Morrow's electric fastball moving around. If it isn't astounding, it's close. Whether Morrow can keep throwing it for strikes is one thing (and by my rough count, his new arm slot produces slightly more pitches in "the strike zone"), but he'll miss a shit tonne MORE bats (13.4%) than he already did (7.6% in the higher slot.) And that's a good thing.
If Bruce Walton's next trick is using this lower arm slot to keep Brandon Morrow healthy, I won't know what to do with myself. Make Walton the new manager! NO WAIT &mdash don't change a thing. Fire up the quality starter assembly line and go with a 162 man rotation! A no-hitter every night! The fun we'll have!!
