Xu Si (Chinese: 徐思; born 24 January 1998) is a Chinese professional snooker player.
Career
Xu Si first started playing snooker aged 12 at his local club in Jieyang during the school holidays. After a few weeks he became determined to become a snooker player.[1]
Xu's second season saw a loss of form. He won only 6 matches and failed to win back-to-back matches in any tournament. His best win was a highly emotional match against Martin Gould in the China Championship qualifying round, which he won 5–4 on the final black. This result allowed him to play in the main event in Guangzhou, close to his hometown of Jieyang, allowing his relatives to see him play professional snooker for the first time. However, he lost to Noppon Saengkham.
In the World Championship Xu produced a magnificent display of scoring to beat Sean O'Sullivan, scoring ten 50+ breaks in successive frames to win the match 10–2. However, he could not repeat this form against Graeme Dott, losing 10–4. His ranking of 77 meant that he was relegated from the tour.
Xu's third season was similar to his second, winning only 4 matches. It came to a premature end when the COVID-19 outbreak forced the suspension of the season. Xu returned to China and did not return for the resumption in July 2020, thereby missing the World Championship. His final ranking was 110.
2020/2021 season
For his fourth season, Xu made some technical changes, adopting the 'Sight Right' method. He also moved to the newly opened Ding Junhui Academy in Sheffield. His results were more consistent, reaching the 3rd round in the UK Championship and the English Open.
In World Championship qualification, Xu needed to win his first match to renew his professional tour card via the 1-year ranking list. His opponent was 7-times World Champion Stephen Hendry, in the third match of his comeback. After a nervous start, Xu won the last 6 frames of the match, with five 50+ breaks, to win 6–1. In the next round he came close to beating top seed Zhou Yuelong, but lost 6–5. He finished the season ranked 77.
During the season, Xu Si lives in Sheffield. In the years 2017-20 he was based at the Victoria Snooker Academy, before moving to the Ding Junhui Snooker Academy in 2020. He has been described as one of the hardest workers on tour. Aside from snooker, Xu enjoys movies and playing computer games.[10]
