Temperamental O’Sullivan warned as Williams’ pressure takes its toll

RONNIE O’SULLIVAN was warned for swearing and title-holder Shaun Murphy suffered a nightmare in the two showpiece quarter-finals of the 888.com World Championship at the Crucible Theatre yesterday.

The afternoon matches involved the quartet who have won the six titles since 2000 and O’Sullivan ended the first session level at 4-4 with Mark Williams.

After the opening two frames had been shared, ‘The Rocket’ vented his frustration in the next.
