Stan Moody held his nerve to clinch a 5-4 win over John Higgins at the World Open in the veteran’s 2,000th professional match.
Higgins, 50, fought back from 4-1 down to square the second-round contest against England’s Moody in Yushan, China.
But the 19-year-old, ranked 47th in the world, made a break of 65 in the deciding frame to knock out the four-time world champion.
“I watched John growing up and learning the game. To beat him in an important match out in China and to do it with a lot of breaks as well is a good feeling,” Moody told World Snooker, external.
“John is a class act. I knew if I let him back in he would come back, so I’m glad I managed to hold my nerve in the decider.”
Moody’s reward for the victory over defending champion Higgins is a third-round meting with Welshman Ryan Day.
Elsewhere at the Yushan Sport Centre, Masters champion Kyren Wilson eased to a 5-2 win over Lyu Haotian, while world number one Judd Trump cruised to a 5-1 success over Florian Nuessle.
World champion Zhao Xintong claimed a 5-4 victory over Chinese compatriot Long Zehuang.
Mark Williams, Gary Wilson and Jackson Page progressed at the expense of Ricky Walden, Aaron Hill and Liu Wenwei respectively.
