Barry Hawkins recovered to beat Ricky Walden 17-14 in his World Championship semi-final and set up a final against Ronnie O'Sullivan at the Crucible.

Hawkins, the world number 14, was 12-8 down at one stage but won nine of the last 11 frames, including a run of eight in a row, to prevail.

Before this year, the Englishman had never gone beyond the second round.

O'Sullivan leads Hawkins 4-1 in head-to-heads and if Hawkins does manage to cause an upset it would rank alongside Joe Johnson's 1986 world final win over Steve Davis in his prime as the biggest in the tournament's history.
