Qualifier Joe Perry set up a second-round tie against Stuart Bingham

Qualifier Joe Perry set up a second-round tie against Stuart Bingham with a 10-7 victory over 2006 world champion Graeme Dott.

Londoner Perry, who now looks set to return to the top 16 next season, went into the final session with a 5-4 lead, which became 6-4 after a break of 104.

But Dott won a close 11th before making 126 in the next to level the match.

Perry then reeled off 132, 82 and 88 breaks, and although Dott won the next, he held his nerve in the 17th to seal the win.

Scottish player Dott, who suffered his 16th straight defeat, explained that he came close to not competing because of his depression problem.

"I had withdrawn from the tournament a few weeks ago," said the 30-year-old.

"The press release had been written and I told my manager to release it but he wanted to wait a week.

"He then introduced me to psychologist Bob Burns He said he didn't want me to come and I wasn't in the frame of mind to play until I picked up my cue last week.

"I am surprised at how I played, I felt great, really back to normal. Joe just beat me. I thought he played unbelievably well. He made four centuries and could easily have had six."

Perry added: "I played really good stuff to get 9-6 ahead but after that the tension was getting bigger and bigger by the minute.

"You try to stay positive but it's only human nature to have that little bit of doubt so I'm relieved to get over the line."
