The myth behind the man
Matsuzaka says 'gyroball' not part of his arsenal
FORT MYERS, Fla. -- Despite highly descriptive news reports, slow motion video and purported eyewitness accounts from major league hitters -- well, the Florida Marlins' scrubs -- Red Sox pitching sensation Daisuke Matsuzaka does not throw a gyroball, G. Gordon Grinch of the North Pole news bureau of SI has learned. Several sources close to Matsuzaka -- and you can't get much closer to Matsuzaka than Matsuzaka himself -- confirmed to Mr. Grinch that Matsuzaka's gyroball is nothing more than media mythology, a promulgation the pitcher delightfully enjoys.
Incidentally, CJ Wilson believes in the Gyroball (although his team mates appear to think otherwise)...
And that DVD you see in the video, here's a direct link if you're interesting in purchasing it. The site (and the video) are both in Japanese so if you need help, drop me a line.
The guy behind the DVD, Tezuka Kazushi, has also released a number of books on pitching and hitting, including one titled "How to throw a Gyroball in 6 Weeks."
I haven't been able to find any info on that that whistle Wilson was using in the video. If I do, I'll post it up.
