Mark Williams turned 50 in March and reached the World Championship final a few weeks later, losing 18-12 to China's Zhao Xintong in May
Mark Williams beat Shaun Murphy 10-3 in the Xi'an Grand Prix final to become the oldest winner of a ranking event.
Aged 50 years and 206 days, three-time world champion Williams eclipsed the record previously held by fellow Welshman Ray Reardon, who was 50 years and 14 days old when he won the Professional Players Tournament in 1982.
The left-hander's 27th ranking title puts him one behind fifth-placed Steve Davis (28) in the all-time list, with Ronnie O'Sullivan leading the way on 41 ranking event wins.
Williams is also the first player to win a tour event in his teens, 20s, 30s, 40s and 50s.
