Stephen Hendry crashed out of the SAGA Insurance Masters at the second round stage after a shock defeat to fellow Scot Alan McManus.
Hendry lost four frames on the spin having led 4-2, slipping to
an unexpected 6-4 loss at the hands of his Bearsden rival at the Wembley Conference Centre.
McManus, who won the title in 1994 when he beat Hendry 9-8 in a memorable final, now plays Welshman Mark Williams in the quarter-finals.
"It's a great win to have under your belt. I always enjoy playing Stephen and feel comfortable playing him," said a happy McManus.
"For some reason I don't feel under pressure. I'm probably the only one expecting myself to win against him. When it went 4-2 I thought he'd run away with the match, but I got some chances and took them.
"I've not beaten Stephen for ages, so it was great to perform out there again in the big arena."
