Ronnie O'Sullivan today made five centuries in the five frames he won to beat Ali Carter 5-2 and reach the Northern Ireland Trophy quarter-finals in Belfast.
Nobody has done this before in a best of nine frame match.
Included in this was the seventh maximum break of his career, completed in the same nonchalent fashion - right and left-handed - as the other four centuries.
This is as good as snooker gets. It was sheer genius.
Whatever anyone may think of O'Sullivan's controversial career, you can only applaud a true sporting great at the top of his game.
