Two days ago, an Australian man named Jason Belmonte walked away with the PBA tour title. He's the first person to win using a two-handed technique:
Apparently, involving both hands allows him to achieve a greater amount of spin (630rpm versus the average professional's 400rpm), creating a significantly more forceful pin strike.
It's amazing to me that a sport as old and as simple as bowling can be revolutionized by single, somewhat obvious innovation. I suppose Jason Belmonte can now join the ranks of Dick Fosbury, Rick Barry, Pete Gogolak, and other sports luminaries who did things the "wrong" way to great effect.
