Judd Trump, Mark Williams and Mark Allen all advance to Xi'an Grand Prix last 16

Judd Trump extended his 100% record this season as he defeated Lyu Haotian 5-1.

Winner of last month's Shanghai Masters, world number two Trump has now won 21 of his last 22 matches in China, a record he has constructed within the past 12 months alongside his ranking title triumphs at the Wuhan Open and World Open.

Several seasoned tournament winners were in brilliant scoring form during the session, including three-time world champion Mark Williams who notched up breaks of 102 and 101 in a 5-2 win against Chris Wakelin.

Barry Hawkins began his tie against Ryan Day with runs of 102 and 104 in back-to-back frames to go 2-0 up. Day levelled at 2-2 (103 break in frame three), but Hawkins took three out of four frames following the mid-session interval to record a 5-3 win.

World Number One Mark Allen was very sharp amongst the balls during his encounter with Xiao Guodong on the main TV table. The 11-time ranking event champion made a statement early on as breaks of 112 and 133 within the opening two frames put him in control, before further efforts of 76, 82, and then a counter-attacking 64 clearance to the final pink in frame seven stamped a 5-2 victory to put him into Thursday's last 16.

In an all-Chinese clash, 17-year-old professional rookie Gong Chenzhi - who eliminated Tom Ford on Monday - saw off Si Jiahui, 5-3.

Jimmy Robertson was made to sweat before going through to round four; the former European Masters champion went 4-0 up on Sunny Akani before his Thai opponent strung together the next three frames (134 break in frame seven) to put the match back in the balance, although Robertson eventually progressed in style with an effort of 117.

An in-form David Gilbert continued his unbeaten start to the season as he dismissed world number 11 Gary Wilson, 5-3. A semi-finalist at the World Championship a few months ago, Gilbert has brought that consistency into the new campaign, and the 43-year-old twice came from behind early on to advance. He is now undefeated in 13 matches.

Jak Jones was the final winner from the afternoon session as he ousted Jack Lisowski in a deciding frame. A break of 111 moved Lisowski 2-0 up, but Crucible finalist and now a top 16 star Jones chalked up the next three frames to go ahead. The contest eventually went all the way and it was Jones who emerged after a crucial contribution of 88 in frame nine.

Jones is set to face Trump in the last 16; the two famously met at the most recent World Championship when Jones sprung a big upset in the quarter-finals.
