Defending champion Adrian Lewis was the first man to book a quarter-final spot in the World Darts Championship as he saw off Wayne Jones 4-0.

Lewis was in dominant form, claiming the first set 3-0 and dropping only four legs in total.

"It's a great feeling to be through to the quarter-finals, and I'm on course to retain my title," Lewis told

"I felt it was a good performance, and I was particularly sharp on the doubles, which was the key to the win."

He will next face Terry Jenkins, who beat Justin Pipe 4-1, delighting the crowd with a double-double finish.

Gary Anderson held off a stiff challenge from South African Devon Petersen to claim the final spot in the last 16.

Anderson claimed 11 180s but struggled to put away his doubles, but his opponent could not take advantage and eventually fell to a 4-2 defeat. He will now face Colin Lloyd, who beat Scott Rand 4-1.
