Dave Harold staged a spectacular comeback to defeat John Parrott on a re-spotted black in the Benson and Hedges Masters at Wembley.

Harold looked dead and buried at 5-1 down but clawed his way back to 5-5.

And the final frame was even more exciting when they tied 56 each.

The black was re-spotted and Harold, who won the Asian Open in 1993 as a 500-1 outsider, kept his composure for a memorable victory.

Parrott could hardly believe it and sneaked away as a jubilant Harold punched the air.

Best win

After the match, Harold said: "I was dead and buried but stuck in there.

"I kept coming back and the longer it went on I knew it was going to go down to the wire.

"You couldn't script a match like this.

"It's one of the best wins of my career."

Harold now faces Ken Doherty or Fergal O'Brien in Saturday's semi-final.
