Jak Jones stunned world number one Judd Trump 4-3 in Group Four of the Champion of Champions at the Mattioli Arena in Leicester on Tuesday, 10 November. The Welshman won the best-of-seven last-16 match to knock the former champion out of the invitational tournament.

Trump, the world number one, had been the favourite to win the group, having won the Champion of Champions once before and reached the final last year, when he lost 10-5 to Mark Selby. Jones, by contrast, arrived in Leicester as the underdog, but held his nerve in the deciding frame to complete one of the shocks of the week.

How the upset unfolded

The match was the second of two afternoon ties in Group Four. Earlier in the day, Australia's Neil Robertson had beaten Thailand's Panchaya Channoi 4-2 to reach the evening quarter-final, where he faced Jones for a place in the semi-finals.

Jones's win means Trump leaves the tournament at the first hurdle. The result also opens up the bottom half of the draw: the winner of the Robertson-Jones quarter-final will meet Chris Wakelin in the semi-finals on Friday, after Wakelin shocked defending champion Selby 6-2 on the opening day.

What is at stake in Leicester

The Champion of Champions, which runs from 9 to 15 November, brings together 16 title winners from the past year. The winner takes home 150,000 pounds from a total prize fund of 440,000 pounds, with the final played over two sessions on Sunday, 15 November.

Ronnie O'Sullivan, a four-time winner of the event, plays his first match on Wednesday, when he faces Shaun Murphy. TNT Sports lists the full results and schedule, and The Sun also records Jones's 4-3 win over Trump in its tournament results.
