Jim Williams books his place in the quarter finals at Lakeside after a 4-3 victory over Conan Whitehead

No 9 seed Jim Williams is through to the last eight after surviving three match darts against Conan Whitehead in a thrilling, see-saw second-round shoot-out.

The match went all the way to a deciding seventh set and Whitehead was only 57 points away from victory when Williams took aim at a 161 check out in the third leg. Williams pulled off his great escape with treble 20, treble 17 and the bulls eye. Whitehead fashioned three match-winning chances in the next leg, but missed and then cracked in the fifth after Williams piled the pressure on his throw with a superb 174. Williams tidied up for a break and then held for the match.
