I've been a fan of baseball for a while now, and I thought I'd seen every kind of pitch there was. I've seen curveballs so good that they make my knees buckle, even while I'm sitting down. I've seen knuckleballs that float like butterflies and (sometimes) get stung like bees. I've seen people just lob a ball to the plate, something I thought would be the pitcher's biggest folly. I've even seen exploding fastballs. I've never seen anything like this, though.
