O'Sullivan reaches last eight at snooker Worlds

Five-time champion Ronnie O'Sullivan beat Matthew Stevens 13-5 to reach his 17th quarter-final at the snooker World Championships here.

O'Sullivan, who claimed his fourth and fifth world crowns in 2012 and 2013 and lost to Mark Selby in the final last year, would level with Steve Davis on six titles if he wins and is just one behind Stephen Hendry's record of seven. He will next face Stuart Bingham in the quarters, reports Xinhua.

"It's going to be a really tough game against Stuart. He beat me in the UK Championship last season and he's really improved as a player," the 39-year-old said on Monday.

Shaun Murphy defeated Joe Perry 13-5 while Judd Trump beat Marco Fu 13-8 to set up a match against China's Ding Junhui. Australia's Neil Robertson ended with a 145 break to beat Ali Carter 13-5.

Murphy, the 2005 winner, will face Anthony McGill in the next round on Tuesday.

Robertson compiled a stunning 145 break - the highest of the tournament - to beat Englishman Carter and faces Barry Hawkins next.
