@Steven_Ellis has a point. This pitch doesn’t even exist. All it really is an exaggerated two-seamer. Stop wasting your time trying to throw a pitch that only certain people know how to throw. You will only see it in Japan, THAT’S IT. No where else because it’s junk, and no one wants junk. Pitching requires practice, not just waving a magic wand and your Roger Clemens or something. I gained 5-10 miles on my fastball, I got better control, I improved my pitching motion as well. It took me about 8 months just to get THAT. I only have a 4-seam and knuckleball. You don’t see people trying to throw wacky stuff in the first place, because it’s WACKY! What I’m saying is leave this pitch behind, and practice pitches that you’ll need. Another thing; it doesn’t matter if you going pro or not. I’m not trying to go pro, but I’m not wasting my time trying to throw some mystery pitch. Also, I apologize for even replying to this. You would have become disinterested if no one really answered you. I decided to reply because I’ve seen this shuuto before and I thought it was cool. I never threw it because there’s no point in throwing it in the first place, it’s so uncommon that there’s not even that much information on how to throw it. Which is exactly what @2022dad is getting at. Let’s just put this discussion to rest.
