Welsh snooker player Matthew Stevens says he will not get "carried away" after his first win over five-time world champion Ronnie O'Sullivan in 12 years.
World number 31 Stevens, came back from 2-0 and 3-2 down to beat world number two O'Sullivan 4-3 in the Welsh Open third round in Cardiff.
"The standard wasn't that good, but I don't care," said Stevens.
"I'm in the next round so it doesn't matter."
He added: "I enjoyed being out there. Playing against Ronnie there's always a full house and especially in Wales it was a nice occasion."
All of Stevens' 2015 matches at the Motorpoint Arena have gone to a deciding frame.
He won the last three frames to come through his first round match against world number 82 Oliver Lines and also beat world number 38 Ken Doherty 4-3 in round two.
The 2003 UK champion said: "I don't look past the first round. It's the best of seven, they are all good players these days.
"I should have lost my first round match. I was 3-1 down. So I'm not going to get carried away, I'm only in the last 16.
"I'm just glad to be in the tournament."
Stevens will now play either world number 11 Marco Fu or Ashley Carty in the last 16.
