Ronnie O'Sullivan bowed out of the Scottish Open on Friday evening, losing 5-2 to quarter-final opponent John Higgins in Glasgow.

O'Sullivan was on the back foot after losing the first three frames, the highlight of which was a break of 88 in the second by Scot Higgins.

Although the five-time world champion won two of the next three - the first with a doubled pink - Higgins finished the contest off in style with a break of 104.

World number three Higgins told worldsnooker.com: "Any time you beat Ronnie it's a special result, even though he didn't play anywhere near his best. He gave me a few chances too many."

O'Sullivan said: "He's a class act and very difficult to break down. You always have to feel you can get back into it otherwise there's no point, but when he's playing like that he'll win a lot of tournaments."

Higgins will face Judd Trump in the best-of-11 frame semi-finals, after the latter defeated fellow Englishman Robert Milkins 5-3.

There was little to choose between the players in the first six frames - but Trump finished strongly and wrapped up victory with a break of 78.

Marco Fu will face Yu De Lu in the other semi-final on Saturday.

Mark Davis won the first frame of his quarter-final against Fu with a 114 clearance, but that was as good as it got as he lost the next five, while Yu edged out Liang Wenbo 5-4 in an all-Chinese contest.
