John Higgins levels astonishing world final with Mark Williams at 15-15 from 14-7 down

Despite a late rally that saw Higgins close to 14-10 behind from 14-7 adrift, Williams - champion in 2000 and 2003 - won the final frame of the third session to boost his hopes of the £425,000 first prize in Sheffield with a 15-10 lead.

But four-times world champion Higgins has won five straight frames to level the final at 15-15 in the race to 18.

Scotsman Higgins has not been at his best in this final and despite battling valiantly against his old foe, he had yet to win a session over the first three sessions until the final session when he has produced breaks of 131, 67, 82 and 62 to win the first five frames.
