A Conversation with Oakland Pitching Coach Scott Emerson
An impromptu conversation will sometimes glean quality interview material, and that was the case earlier this season when I chewed the fat with Scott Emerson in the visiting dugout at Fenway Park. The Oakland pitching coach loves discussing his craft, and that fact came to the fore when an answer to a question about an individual member of the A’s staff segued into what you’re about read here. From the importance of staying closed in a delivery to the value of disrupting timing and attacking weaknesses — with boxing, bullets, and airplane analogies thrown in for good measure — Emerson had a lot to offer.

Scott Emerson on pitching: “Some guys can create the analytic everybody is looking for with a bad delivery. What I mean by that is they bail out in their delivery and the hitters see the ball better. We can’t quantify the hitters seeing the ball, but the longer they see it — no matter what the spin rates are — the more it takes away from the effectiveness of the pitch. It gives the hitter the advantage.
“Sometimes it’s, ‘Oh, this guy can spin it,’ and people are wondering ‘Why does he have a 6.00 ERA?’ Well, he has a 6.00 ERA because he doesn’t hang onto his mechanics well enough. He exposes the ball to the hitter sooner. It’s like a boxer bailing out on a punch. If we’re boxing and I open up too much, I’m exposed and you can hit me with a left hook. But if I’m driving through you, I’m not exposing myself. I’m not giving you the opportunity to beat me up.
“For instance, when Daniel Mengden is really good, he stays closed longer. He’s down the lane, down the slope, closed, and then he explodes out of it. When he gets himself in trouble is when he wants to overthrow. His front shoulder bails out and he exposes the baseball to the hitter. That gets him in trouble.
