Last time we checked in with William Polly, the 10-year-old Penrose resident had just set a new sport stacking world record and was showing off his skills on the Tonight Show with Jay Leno.

Polly, now 11, is still up to his winning ways in the world of sport stacking – a competitive sport that involves stacking cups in set formations — or “sequences” — as quickly as possible.

Last month Polly set a new world record in the “individual cycle” competition. Unfortunately, his record was quickly broken by fellow young sport stacking phenom, William Orrell.

Then, at a national competition in Colorado Springs last weekend, Polly tied a world record in the 3-6-3 sequence (see video, above) and set a record with three fellow stackers in the 3-6-3 relay.

Polly now has his name on three of the five sport stacking world records.
