Fifteen-year-old amateur Yuan Sijun thrashed Martin Gould 5-0 to reach the second round of the China Open in Beijing.
The wild card racked up breaks of 51, 102 and 55 against world number 13 Gould to set up a meeting with former world champion Graeme Dott.
Yuan said on worldsnooker.com: "I felt good in general and my opponent left chances for me, so I managed to make some decent breaks.
"My coach told me that I needed to work on clearing the colours and long potting and I think it worked.
"My parents are not with me here because their presence would have made me nervous, which has happened before. Two wins in a row is a breakthrough for me."
