Scottish Open: Judd Trump and Ronnie O'Sullivan beaten in Glasgow
World champion Judd Trump followed Ronnie O'Sullivan in being bumped out of the Scottish Open quarter-finals.
In all-English contests, Trump slumped to a 5-2 defeat by David Gilbert, while O'Sullivan lost 5-4 to Mark Selby.
As Gilbert and Selby contest one semi-final, fellow Englishman Jack Lisowski will face Northern Ireland's defending champion, Mark Allen, on Saturday.
Lisowski ousted Thailand's Thepchaiya Un-Nooh 5-3, while Allan eased aside Scotland's Scott Donaldson 5-1.
Selby playfully responded to O'Sullivan's fist-bump greeting with a rock paper scissors style grab of his hand as the pair prepared for the first frame at Glasgow's Emirates Arena.
Former world champion and current number three O'Sullivan had made headlines after his second-round tie by saying he fist-bumped opponent James Cahill and the referee because "I'm a bit OCD with germs".
"I am not sure about his fist bumps and all that, but as far as on the table, he is a great, great player," three-time world champion Selby said.
"Every time I play Ronnie, I always see myself as the underdog, irrelevant of what I have won in the game. In my eyes, he is the best player to have played the game."
The world number six started with an impressive break of 120 and, despite O'Sullivan firing back with three century breaks in four frames, responded by winning the final two frames.
O'Sullivan paid tribute to Selby's resilience, saying: "He played good stuff, good safety and a brilliant break at the end under pressure. That's what champions are made of. I'm happy with my performance this week."
Gilbert, Allen and Lisowski ease through
Trump started on the front foot against Gilbert by taking the opening frame, but breaks of 71 and 98, followed by a scrappy fourth frame, put the world number 11 3-1 ahead.
Although Trump conjured up a break of 101 to narrow the deficit, Gilbert clinched victory with breaks of 142 and 53 to secure his progress.
While holder Allen complained about the scheduling of his games, he still managed to ease to victory, responding to world number 26 Donaldson winning the second frame by taking the next four, included one century.
Lisowski, ranked 14, continued the form that ousted former world champion in the previous round and was never behind as he defeated Thailand's world number 20, with the highlight being a break of 143.
