Si Xu

Bio

China’s Xu Si is a two-time ranking event semi-finalist who enjoyed the best season of his career to date so far during the 2024/25 campaign to earn a new career-high world ranking of 38. 

Having turned professional in 2017, Xu made an immediate impression as he reached the last four stage of the Indian Open following victories over Michael Georgiou, Robin Hull, Sean O’Sullivan, Ricky Walden and David Gilbert, before he lost out to John Higgins in the last four.

He would have to wait seven years to again reach the semi-finals of a ranking event as he defeated former world champion Judd Trump at the International Championship before eventually falling to compatriot Ding Junhui in the penultimate round.

In November 2023, Xu compiled the first 147 break of his career in the UK Championship qualifiers against Ma Hailong and, three months later, rose to a career-high ranking of 55th.

Two further maximum breaks would come during the 2024/25 season, at the International Championship and most recently at the Welsh Open qualifiers.

Amateur Career

Prior to turning professional Xu had already competed at the wildcard round of several ranking event tournaments, notably defeating Mark Williams at the 2016 International Championship to reach the last 32 before losing to James Wattana.

After he dropped off the circuit at the end of the 2018/19 season, Xu immediately regained his main tour place by successfully winning five matches at Q School Event 1 in Wigan.
