LLWS Redux

I'm watching a rerun of the final game of this year's Little League World Series, catching the inning that we missed last Sunday. Vonn Fe'ao is pitching 78-79 MPH fastballs, which is the equivalent of 100+ MPH in the bigs. So fast, as the announcers said, it's off the equivalency charts. I'm surprised he's not ripping his own arm off.
