Iran’s Hossein Vafaei became the first qualifier to beat a seeded player at the 2026 World Championship as he defeated China’s Si Jiahui 10-3 to set up a tie with world number one Judd Trump.

Si, a semi-finalist in 2023, held a 3-1 lead, but 31-year-old Vafaei, ranked 32nd in the world, won nine frames in a row, thanks to breaks of 81, 61, 60, 105, 53, 78 and 68.

Over the last three frames of the first session on Wednesday and the four frames on Thursday, 15th seed Si only scored a combined 64 points as Vafaei impressed.

He will play 2019 winner Trump next and said: “He is one of my friends and a nice guy on and off the table. He is the world number one so it’s the best match.

“I’m getting a lot of support from back home and they would love me to do very good in this tournament.

“Si is one of the best players China has so a tough opponent for me, I respect his game and I’m one of his fans, he is such a great player.”
