Kellett also qualified for the 2011 BDO World Darts Championship, again as the second seed. He defeated two-time semi-finalist and pub teammate Darryl Fitton 3-0 in the first round, losing just one leg along the way. Bookmakers slashed his odds of winning the championship from 16/1 to 9/2 after this performance, but he was unable to produce the same standard against Jan Dekker in the second round and lost 4-1. During this tournament commentators and pundits began affectionately referring to Kellett as the 'cocky craftsman' (in a nod to Eric Bristow), due to his confidence on-stage in comparison to his otherwise humble nature off it.
