"borderline inverted w"
I live in san francisco and the announcers are always talking about how matt cains velocity looks faster because he short arms the ball. By short arming they mean the time it takes him to bring to ball to the cocked position is much shorter, giving the batter a shorter look at the ball.
Announcer 1: "Yes matt cains more of a borderline inverted w"
Announcer 2: "Thats right fred!"
Find me a short armer and i'd love to see it for comparisons sake, but for now i'll stick with the guys with the credentials.
