Snooker-Amateur Cahill beats O'Sullivan in first round of world championship

Five-times world champion Ronnie O'Sullivan was knocked out of the World Snooker Championship by amateur James Cahill at Sheffield's Crucible Theatre on Tuesday in one of the biggest shocks in the tournament's history.

The unranked debutant Cahill, who is the first amateur to play at the Crucible, beat O'Sullivan 10-8 to advance to the second round at the expense of the world number one who has 36 ranking titles.
