Cool article/video. I wonder if, now that studies have shown that it's not dangerous, more pitchers will begin using it. What do you think? Could be a good way to revise a fading career for some older players.
A kid I went to highschool with was really into baseball (damn good at it too, really nice guy. I hope he makes it big some day) and he did a presentation on screwballs. It was actually pretty cool. He talked about some of this stuff and it was the only time I've ever been interested in baseball.
