Below are tables showing the performance that can be expected from high school,  college, and professional
major league pitchers.  A great difference exists in the spin rates created by poor vs. exceptional breaking ball
pitchers.  


BASEBALL
A good breaking ball at the college or pro level requires at least 35 RPS.  Some pitchers achieve more than
40 RPS consistently on their curveballs or sliders.  In high school, the best breaking balls are typically around
35 RPS.  There is more variability in the spin rate on fastballs, depending on the type of fastball thrown and
whether the pitcher is capable of putting movement on the pitch.











The best pro pitchers like Justin Verlander throw a curveball at 45 to 50 RPS.  An article by Tom Verducci
about the spin rate of pitches in Major League Baseball (see at
Verducci - Sports Illustrated) indicates the
following advantage for high spin curveballs:











The MLB data above shows that a curveball with very high spin is twice as likely to result in a strike than
one with low spin and 50% more likely to result in a strike than a curveball with average spin.  Very high spin
versus low spin results in a 32% decrease in batter hitting average and a 47% decrease in batter slugging
percentage (total bases/at-bats).

SOFTBALL
A good breaking ball (curveball, riseball, dropball, or screwball) requires at least 19 RPS.  Some pitchers
achieve more than 22 RPS consistently with their breaking balls.  A few are known to throw riseballs
consistently at 30 RPS.  In high school the best breaking balls pitchers typically throw around 23 RPS.  There
is more variability in the spin rate on fastballs, depending on the type of fastball thrown and whether the
pitcher is trying to put movement on the pitch.  Although the spin rates for fastpitch softball are slower than for
baseball, the effect of spin is more pronounced than with baseballs because of the larger surface area and
higher seams of a softball.
