World champion Kyren Wilson and Mark Allen are both out of the Welsh Open after suffering shock defeats in the second round in Llandudno.
Wilson, heavily fancied to reach the business end of the tournament with Judd Trump and Ronnie O'Sullivan absent, came through a tough match against Marco Fu in his first match but was dumped out by Joe O'Connor 4-3 in a final-frame decider.
The door had opened for Wilson to overtake Neil Robertson in the race for the £150,000 (€179.8k) BetVictor Series bonus after the latter's exit, but he was unable to capitalise.
Meanwhile, Allen suffered a 4-3 defeat to Yuan Sijun of China. Yuan took the opening frame, but the world number eight from Antrim responded with breaks of 52 and 105 to move into the lead.
A scrappy fourth frame went the way of Yuan, who then edged ahead with a knock of 70 in the fifth frame.
Allen forced a decider in which the Chinese player prevailed on a 81-59 scoreline to advance.
Elsewhere home favourite Mark Williams saw his hopes of rolling back the years at the Welsh Open go up in smoke.
The world number five is a two-time winner of the tournament, as long ago as 1996 and 1999, but was unable to mount a charge as he succumbed 4-2 to Stephen Maguire.
Maguire got the better of Williams in a workmanlike contest, keeping his own prospects of qualifying for next month's World Grand Prix via a final-four finish.
Welsh trio Jackson Page, Matthew Stevens and Jamie Jones remained in the hunt after they made their way into the last 16.
Jamie Clarke, another local hope, benefited from a bye following O'Sullivan's late withdrawal but was unable to take advantage as he went down 4-3 to Matthew Selt.
Robertson was on the wrong end of an unexpected defeat, beaten 4-3 by Tom Ford. Robertson forced a decider after going 3-0 down, but found Ford in clinical form as he reeled off a break of 131.
John Higgins, who has won this tournament on a record five occasions, completed his serene progress through the draw by following up a 4-0 win over Graeme Dott with the same score against Robert Milkins.
