Since a proper ranking tournament circuit was established, no player has ever won all the titles on offer in a single season.
Stephen Hendry came closest in the 1990/91 campaign when he captured five of the eight titles on offer.
Could Ronnie O’Sullivan complete a grand slam this season?
It’s unlikely but not impossible.
Because he is not playing at his very best all the time but still winning titles. Even at 80% of his game he is still the best around at the moment as he proved in winning the Northern Ireland Trophy last night.
Whether this amuses, embarrasses or doesn’t interest him at all I don’t know but he's untouchable at the moment and the challenge for the other top players is to raise their games and stop him running away with most of the silverware this season.
