World Snooker Championship 2024 results: Jak Jones beats Zhang Anda, Mark Selby trails Joe O’Connor

Four-time world champion Mark Selby is in danger of a shock first-round exit after Crucible debutant Joe O’Connor moved into a commanding 7-2 lead.

O’Connor, 30th in the world, only needs three frames to reach the last 16 when the match resumes on Monday.

It would be another huge shock after 2023 champion Luca Brecel lost to David Gilbert in a major upset on Saturday.

Elsewhere, Welsh qualifier Jak Jones produced a superb performance to defeat China’s 11th seed Zhang Anda 10-4.

Jones, a quarter-finalist last year, is ranked 44th in the world and had to fight through two qualifying rounds, with his win meaning two seeded players have been knocked out in two completed matches.

“We both probably suffered from nerves a bit, he missed a few balls and that can get on top of you but I’m just happy to get through,” said Jones.

“I wouldn’t say I felt comfortable. I’ve only played one [tournament] match in the last two months but in a best-of-19 you can get some sharpness and match practice.”
