Pitch Framing Newsbeat

Saturday, April 18, 2015

Dodgers A.J. Ellis, Yasmani Grandal caught up in framing a pitch for strikes

[A.J.] Ellis has ranked among the worst framers (catchers who get fewer strike calls than they should as measured by, again, Pitch f/x) in the majors the past few seasons. That put him in an uncomfortable situation this past winter with the Dodgers’ front office now in the hands of a coterie of highly sophisticated, analytically inclined decision-makers who believe strongly in the value of the pitch-framing metrics.

“I’ll be honest – I was motivated by the realization that that aspect of catching was becoming highly valued by this new wave of analytical front-office types,” said Ellis, who spent time during the off-season working to improve his pitch-framing skills with Milwaukee Brewers bullpen catcher Marcus Hanel. “And I knew that deficiency in the long run could affect my future employment.” ...

They have a very smart group of people upstairs. [Ellis said] They can isolate it… when they explained that to us in spring training, ran us through the process and laid it out for us, it strengthened my understanding of it and my commitment to what they’re doing – because they’re doing it the right way. It got me on board, is what I’m saying.” ...

Yasmani Grandal was already on board – without really knowing it.

Grandal does not have a reputation as a good defensive catcher. But he ranks very high as a pitch framer and that was a big factor in the Dodgers’ desire to acquire him from the San Diego Padres this winter…

Bad news for Ellis, though. While there are techniques that can improve the way a catcher receives the ball, pitch framing appears to be an innate skill that you either have or you don’t.

“The really interesting thing about framing for me is – it is pretty much one of, if not the, most persistent skills in baseball,” [GM Farhan] Zaidi said. “A batting average will fluctuate, a pitcher’s ERA will fluctuate way more than this metric of catcher framing will fluctuate… Obviously, Yasmani is working with an entirely different set of pitchers. He was a top-five framer last year. He’s a top-five framer now.”

How Jonathan Lucroy makes batters swing at bad pitches | FOX Sports

Quantifying a catcher’s ability to steal strikes is one of the great sabermetric advances over the last ten years.

But what I have established here is that the effect of a good receiver extends beyond the pitches that batters let go by. A good framer, by changing the probability of a strike at the edge, causes the opposing hitter to modify his own behavior, causing him to swing at pitches a little bit further from the center of the zone. In addition to harming the batter’€™s chances directly, by flipping balls to strikes, a good framer changes the dynamics of the at-bat indirectly as well. This effect suggests that the numbers we’€™ve generated to date for the value of framing are probably underestimates, which is good news for all the steady receivers of the world.
