Jameson Taillon’s road to recovery took him down baseball’s new path

As he went through it, Boddy read about what Tezuka called the “elbow spiral” motion, or, in essence, a shorter arm path. It was a common throwing motion seen in professional pitchers in Japan, which Boddy theorized was caused by the great volume of throwing they did. In the text, Tezuka advocated for the shorter arm path, in which the initial, back-side part of the motion does not extend the arm toward second base as Taillon did; rather, it kept the arm nearer the body. It was more like how a quarterback threw.

In technical terms, the core concept married external, or outward, shoulder rotation to supination of the arm, meaning the forearm was in a forward-facing, more relaxed position. Supination is the opposite of pronation, the twisting of the forearm that forces the palm outward and thumb toward the ground. Pronation happens naturally as pitchers release the ball and follow through. But Tezuka posited there should be no pronation of the pitching arm at that early stage of the throwing motion like Taillon and many others did.

By condensing the throwing motion, it also better allowed for the proper sequencing of the delivery. If one thought about it as an engineer, one was essentially reducing unnecessary parts.

“It was like, ‘Oh, wow, this is an interesting concept,’” Boddy said.

I hope this doesn't get lost in the shuffle because it is kind of an interesting article on some different mechanics for pitchers where they keep their arm path short instead of extending (boring headline though!). I must admit, I've seen Bieber and Giolito throw a lot and had not noticed that tweak.

Headline makes it sound like he found religion.

But low-strain deliveries are common in Japan. Way more side-arm and submarine pitchers than you see here. I've always guessed it's because, back in the day, Japanese pitchers were asked to throw insane numbers of innings. (And more often than not, burned out after a couple years.)

A few more guys (to my untrained eye): Plesac, Bauer, Darvish, Fairbanks

Robbie Ray tried it last season, was terrible and ditched it.

Taillon getting mixed results -- ERA over 5, 75 ERA+, FIP better at 4.5 ... Ks way up over 11 with control but HRs through the roof (2.2/9). Of course just 33 innings.

Of course just 33 innings.


And coming off a long injury layoff, with the UCL repair.
