Yu Darvish unveiled a new pitch called the “gyro-cutter” in his All-Star appearance this year. According to the linked article, he had just shown it in practice on the 21st. Said Darvish: “it’s the first time I used it in a game. It’s one type of cut fastball. Just the trajectory is different from what we’ve had until now.”

Hat tip to Tommy Bennett for the link. Patrick’s got video of the pitch up on his site if you’re interested in its, ahh, gyrations. Obviously I’m no expert in the workings of the gyroball or Darvish’s new gyro-cutter, but it’s definitely cool that a 24-year-old who has been dominating the NPB for four seasons is inventing new pitches and honing his game.
I know Darvish has said he’d like to stay in Japan, and to some extent I think that’s pretty awesome. But on a selfish level I want to see this guy pitch more often and that’s not going to happen until if and when he comes stateside. Plus, you know, top competition and all that.
Meanwhile, this guy doesn’t see what’s so novel about a gyro-cutter:

You want to see a slab of vertical meat cut (and who doesn’t) you must go to Yatagan on McDougal and get the doner — BEST SANDWICH IN TOWN. Yes, that’s a challenge, Berg. http://chowhound.chow.com/topics/218327?tag=footer_recommendation%3bboard_discussion_module_small And I know you’ve had it because you’ve managed to squeeze every flippin’ one made in creation into your schedule (and your gut; and, yes, I’m jealous).
