1. R.A. Dickey on the spin of a perfect knuckleball:




As a conventional pitcher, you throw a fastball, a curveball, a slider, a change-up — and those pitches are all thrown with a certain amount of spin on them. With a knuckleball, you’re doing the opposite. You’re taking spin completely off the baseball and you’re leaving it up to the physics of air resistance and seams on the baseball. … So, a perfectly thrown knuckleball has a little less than a quarter rotation from the time it leaves your hand until the time that it gets to the catcher’s mitt.
