Ronnie O’Sullivan cut a frustrated figure despite coming from 3-1 down to end the opening session of his World Championship quarter-final level at 4-4 with Stuart Bingham.

The seven-time world champion missed several uncharacteristic pots and rapped his cue against the table in the seventh frame.

Bingham the winner in 2015, made four half-century breaks, while ‘The Rocket’ knocked in two and the only century of the match in the fifth frame.

Meanwhile, four-time champion John Higgins recovered from a 4-0 deficit to trail Kyren Wilson 5-3.

Earlier on Tuesday, Judd Trump and Jak Jones finished a hard-fought opening session to their last-eight contest at 4-4 and David Gilbert established a commanding 7-1 lead over Stephen Maguire.

Bingham memorably defeated O’Sullivan at the same stage on the way to his own triumph at the Crucible nine years ago.

And he appeared to settle quicker with breaks of 55, 75 and 79, enabling him to take three of the first four frames against a misfiring O’Sullivan.

But having suggested that he would have to be close “to perfect” to defeat the current world number one and 41-time ranking event winner, Bingham was unable to maintain that early pressure.

A wonderful break of 116 helped O’Sullivan reel off three consecutive frames before Bingham was able to respond with a 72 of his own.
