Ronnie O'Sullivan is guaranteed to be world no.1 again next season after beating Stuart Bingham 10-5 in the first round of the Betfred.com World Championship.
This was not O'Sullivan at his imperious best but the defending champion still made three centuries and finished off with 365 points without reply.
It means his closest challenger in the rankings, Stephen Maguire, cannot catch him even if the Scot wins the title.
O'Sullivan will need to improve his long potting and safety but you can always improve as long as you are in the tournament.
Bingham will reflect on what was a rotten draw to get. He played well in patches and probably would have beaten some of the other players in the event, but was up against the heaviest scorer in the game.
