Jimmy White undone by Jack Lisowski at German Masters

White, a former Masters and UK Championship winner, was the first player aged 60-plus to reach that stage of a ranking event since Eddie Charlton at the 1992 British Open.

The six-time World Championship runner-up looked to have continued his momentum from Wednesday as he took the first two frames against his fellow Englishman, 29 years his junior, to threaten an upset.

However, that was as good as it got for White as Lisowski, a runner-up in Berlin two years ago, sparked into life to rattle off five successive frames and book his place in the quarter-finals.

"I can't really celebrate beating him. I think he put me under a lot of pressure at the start," Liswoski told World Snooker Tour.

"He could have gone 3-1 up at the interval but getting out at 2-2 kept me in the game and I was lucky to survive that fourth frame."

He will meet China's Xiao Guodong, who reached the last eight for the second time in a fortnight having previously done so at the World Grand Prix, after he beat Elliot Slessor 5-1.

World number eight Kyren Wilson eased past Jimmy Robertson 5-2 with Tom Ford defeating Tian Pengfei 5-3 in the closest contest of the evening session.

In the afternoon matches Neil Robertson battled back from 3-1 down to friend and practice partner Joe Perry, the Welsh Open champion, to eventually win 5-3 as he got over the line with breaks of 96 and 118.

He now faces Snooker Shoot Out winner Chris Wakelin, a 5-4 conqueror of Si Jiahui 5-4, in the last 16.
