Former world champions John Higgins and Shaun Murphy suffered shock exits at the German Masters qualifiers at the Barnsley Metrodome on Friday.
Zhao Xintong beat four-time world champion Higgins 5-1, with top breaks of 76, 72 and 92.
Yan Bingtao edged out 2005 Crucible champion Murphy 5-4, despite the latter producing breaks of 133, 80 and 117.
Sixteen-year-old Bingtao and Xintong, 19, live in South Yorkshire and are based at Sheffield’s Victoria Snooker Academy.
The Chinese teenagers have now qualified for the German Masters in February, at the Tempodrom in Berlin.
Another big-name casualty to fall in Barnsley yesterday was world No 3 Judd Trump, crushed 5-1 by Tom Ford.
Sheffield’s Adam Duffy lost 5-2 to Northern Ireland’s Mark Allen.
Former world champion Neil Robertson beat Doncaster rookie Chris Keogan 5-1.
Barnsley Metrodome has hosted 128 players, who needed to win two qualifying matches to reach the last 32 who will travel to Berlin.
Barnsley has seen two maximum 147s in qualifying this week.
First Ali Carter cleared up against Wang Yuchen, then minutes later Scotland’s Ross Muir repeated the rare feat against Brazil’s Itaro Santos.
Unfortunately, the pair will have to share the £1,000 qualifying 147 prize, after the £11,000 rolling pot was emptied by Murphy at the European Masters qualifiers in Preston.
That makes it 126 maximums in snooker history, and the tally for this season now stands at eight.
Next week the spotlight turns to the Coral Scottish Open.
