This guy who won't show you how to grip or throw the "shuuto" reminds me of a fellow named Deacon Johnson (or Jones, depending on which account you read). Johnson (or Jones) was an old-time pitcher in the AA Southern Association in the late 30s and early 40s, and he threw a bewildering breaking pitch which for want of a better name he called the "slip" pitch. He was a selfish coot who wouldn't even show it to his own manager, Paul Richards, who wanted to know more about the pitch because he had to catch it. Johnson, or Jones, wanted to keep it his own little secret. Question: If he wanted to keep it a secret, why was he throwing it?
Okay. There is nothing new or mysterious about the "shuuto". I remember that pitch very well, because the Seattle Mariners had a relief pitcher, either a set-up man or a closer, named Shigetoshi Hasegawa, who threw it all the time. I watched him throw it, and I was able to determine that it was a changeup screwball like the one Joey Jay used to throw when he pitched for Cincinnati in the early 60s. As Jay described it, you just turn it over a little. My guess is that the seemingly controversial "gyroball" is just a variation of the shuuto, only a little faster.
There's nothing new under the sun, or the moon, or in a pitcher's repertoire. 8) :baseballpitcher:
