Ronnie O’Sullivan hailed the impact intermittent fasting has had on his energy levels during this year’s World Snooker Championship after seeing off Ryan Day to reach the quarter-finals.

The 48-year-old, who is bidding to secure a record eighth Crucible crown, eased his way into the last eight after winning three of the four frames on Monday afternoon to wrap up a 13-7 victory against Welshman Day.
