Seven-time world champion Ronnie O'Sullivan suffered an early exit at the Northern Ireland Open after falling to Ka Wai Cheung in a deciding frame during the opening round of the tournament, according to reporting by BBC Sport.
The defeat marks an abrupt end to O'Sullivan's return to the event, extending a recent stretch of disappointing form for one of snooker's most accomplished competitors.
Deciding-Frame Defeat
Cheung held his composure to close out the contest against the veteran cueist, taking the match to the final frame before securing the victory. While O'Sullivan entered the tournament as a primary contender, Cheung capitalized on his opportunities to ensure the seven-time world champion bowed out in the initial stage of play.
The result produced an immediate upset in the draw, removing a headline attraction from the competition before the later rounds had even taken shape.
Continuing Struggle on the Table
O'Sullivan's departure in the first round follows a challenging period of form across recent outings. Despite his extensive record of major titles and decades at the top of the sport, the defeat to Cheung highlights the ongoing difficulties the world champion has faced in generating consistent winning momentum.
With O'Sullivan eliminated, Cheung progresses into the subsequent rounds of the Northern Ireland Open, while the veteran departs early to address the persistent dip in his competitive performances.
