Waites bags BDO title
DARTS: Scott Waites cruised to his first BDO World Championship title after beating Tony O'Shea 7-1 in a one-sided final.
Waites was ruthless as he raced to a 5-0 lead, taking 10 legs in a row at one point as O'Shea almost folded completely in his third final.
O'Shea won the sixth set to ensure there would be no whitewash, but any hopes of a comeback were quickly dismissed with Waites claiming the next, and although there was a hint the third seed was feeling the pressure, he managed to hold his nerve.
