Mark Williams was one of the biggest casualties on day two of the British Open at the Marshall Arena in Milton Keynes.
The Welshman, who triumphed in the event just over twelve months ago, was far from his best and suffered a 4-1 loss to Ben Woollaston.
Williams got off the mark in good fashion with a break of 78 in the first frame but lost the subsequent four frames to see his British Open defence end prematurely.
Recent European Masters champion Kyren Wilson also bowed out on Tuesday, ousted by the very man he beat to seal glory in Fürth last month.
Barry Hawkins scored heavily with breaks of 134, 120, 78, 72, and 53 helping him to gain a modicum of revenge for that title-deciding reverse.
Another star to bow out was John Higgins, who described his missed match ball in the deciding frame as “unforgivable”.
The Scot compiled his 900th career century break but was ultimately pipped by Yuan Sijun on the final black.
Several marquee names did manage to make it through to the last 32 of the random draw, however.
Zhao Xintong produced one of the performances of the day in a 4-1 victory over Stuart Bingham that included a hat-trick of century contributions.
Four-time world champion Mark Selby also looked solid during his 4-1 success against Mark Joyce.
The Jester endured a difficult 2021/22 campaign and needs to improve his form if he’s to maintain his status near the top of the rankings list.
Some of the other notable names to progress were Jack Lisowski, Graeme Dott, and Jordan Brown.
On Wednesday, the round of 64 concludes with Judd Trump among those in action before the last 32 gets under way.
