O`Sullivan storms back to reach quarter: Finals

Sheffield: Defending champion Ronnie `Rocket` O`Sullivan produced some world class snooker to come from behind and reach the World Championship quarter-finals with a 13 frames to 11 victory over Joe Perry on Saturday.

The 38-year-old Englishman -- bidding for a sixth world title at the Crucible Theatre in Sheffield, England -- had trailed 9-7 overnight and having shared the opening four frames of the final session O`Sullivan was just two frames from defeat. However, suddenly the mercurial cuesman -- whose brilliance has been offset by regular clashes with the sport`s authorities -- found his touch and barely allowed Perry a look-in. Breaks of 53 and then 52 were enough to level the match and then he upped the ante with a wonderful break of 124 to take the lead in the match for the first time. Perry`s spark had completely gone and a loose safety shot by the 39-year-old Englishman in the 24th frame gave O`Sullivan his chance and he took it in style firing off a break of 113 to round off a remarkable sequence of frames. O`Sullivan will play either Rickey Walden or another Englishman Barry Hawkins in the last eight. The Walden and Hawkins match, a rematch of last year`s semi-final which the latter won, will resume later on Saturday with Walden leading 9-7.
