"This is going to be a long, drawn-out fight. While the goal is to keep ball-exit speed below the 97 mph measured for a reference wood bat, professor Daniel Russell of Kettering University posits that ball-exit speeds of over 102 mph are possible for a strong player with a fast 115-mph swing using a BESR certified nonwood bat. I find it very hard to believe having an extra 0.020s to react to a line drive would make any difference in whether or not a pitcher would be able to protect himself. Easy editing on desktops, tablets, and smartphones. *There is a subtlety involved in the calculation of BBS, namely that the BESR depends on the Bat-Ball-Coefficient-Of-Restitution (BBCOR) which in turn depends on the relative speed between bat and ball. The faster the speed, the lower the BBCOR. If a stronger player was able to swing the same bat with a bat-swing speed of 76-mph at a 70-mph pitched ball, the batted-ball speed would increase to about 108-mph*.

Proponents of the bans suggest that aluminum bats allow for higher ball-exit speed, which endangers pitchers, while opponents suggest that existing regulations are sufficient to restrict batted-ball speeds. "I find it very hard to believe having an extra 0.02 seconds to react to a line drive would make any difference in whether or not a pitcher would be able to protect himself," Russell says. The pitcher threw the ball and then had to react from his follow-through position and attempt to deflect the ball batted back directly towards him. Since the California legislation calls for a one-year moratorium, one possible outcome is that it will pressure bat manufacturers to adopt stricter BESR standards.

For the Brown University field study, pitched-ball speeds ranged from 48-mph to 66-mph with the average pitched-ball speed being 57-mph. The typical arguments in favor of banning metal bats, arguments that metal bats present a dangerous and intolerable safety risk, usually rely on two assumptions: The speed with which a baseball leaves the bat (the Batted-Ball Speed) depends on three factors: the pitched-ball speed vball, the bat-swing speed vbat, and the Ball-Exit-Speed-Ratio (BESR) which represents the effectiveness of the collision between bat and ball. Burton at the University of Minnesota investigated the response times of college baseball pitchers and infielders in an unpublished dissertation I haven't yet been able to obtain a copy of this dissertation to read it myself, but Dr. Trey Crisco summarized their conclusions in his report to the NCAA.
