Ronnie O'Sullivan briefly walked out during the first frame of his World Open match against Ross Muir after being distracted by a sponsorship logo stitched onto his waistcoat. The seven-time world champion scratched at the red patch before exiting the auditorium, causing a delay of several minutes.
O'Sullivan returned following alterations to his garment and went on to claim the first frame, eventually winning the match 5-1 in Yushan, China. Despite continued fidgeting with his waistcoat, he played well in his first tournament appearance since early February.
The opening frame had already been interrupted by an insect landing on the cueball, but O'Sullivan capitalised to take an early lead. He produced a break of 83 in the second frame and was 3-0 ahead before Muir pulled one back. O'Sullivan then came close to an 18th career 147 break in the fifth frame but potted the white when sinking the 15th black.
He sealed victory with a break of 114, setting up a third-round meeting with Matthew Selt. The 50-year-old, currently 12th in the world rankings, needs a strong performance to protect his place ahead of next month's World Championships at the Crucible.
