Luo Honghao knocked Mark Allen out of the Championship League in Milton Keynes, where 16-year-old Jamie Wilson impressed on his professional debut.
World number five Allen had been held to a 2-2 draw by Wilson, which earned the teenager a point from the opening best-of-four frames match of Group 9.
Wilson, who secured a two-year place on the professional tour via the sport's qualification format, Q School, found the going tougher against 20-year-old Chinese player Luo, who coasted to a 3-0 victory.
The Havant teenager then claimed another 2-2 draw against Billy Castle, which saw him earn £1,000 in prize money.
It was world number 60 Luo who qualified for the next stage after taking a point off Allen in their showdown to top the group.
On the other table, Thailand's Thepchaiya Un-Nooh progressed from Group 19 after the world number 18 finished one point ahead of Sunny Akani with two victories and a draw.
The 32 group winners advance to a second stage, which features eight groups of four and starts on October 26.
The last eight will then be split into groups to play on October 30, followed by a best-of-five-frames final between the winners.
