Ronnie O'Sullivan brushed aside James Cahill to comfortably progress to the third round of the Scottish Open after causing a stir over his reluctance to shake hands before the match.
The Rocket was not keen on shaking hands with either his opponent or the referee and attempted to fist bump both instead.
"I'll admit I'm a bit OCD with germs," O'Sullivan explained to Eurosport after the match.

"I don't open door handles, I always have tissues on door handles. I am a bit OCD like that.
"I have got a bit of a germ thing. It's easier to do that and I don't get any germs."
O'Sullivan suffered a shock defeat to 23-year-old Cahill during last season's World Championship, but took just over 30 minutes to secure a dominant whitewash.
Misses from Cahill smoothed a path for O'Sullivan to take the first two frames, with the third following despite the five-time World Champion missing a black off the spot.

The match was put to bed when O'Sullivan neatly claimed the fourth frame with a break of 86, averaging at 12 seconds a shot throughout the performance.
"It didn't feel like 12 seconds, it felt like 21 seconds," he told Eurosport after the victory.
"I felt like I was playing slower tonight, I came out and tried to play a little bit more conservative because I have been a bit too attacking I think. I just tried to rein it in a bit, so it meant I had to take a bit more time on my shots."
