March 20 - Ronnie O'Sullivan snookered his opponent to earn a free ball and cleared the table to make the highest break in the sport's history with a 153, six more than the maximum 147, during his quarter-final with Ryan Day at the World Open on Friday.

O'Sullivan left Day's cue ball positioned behind other balls at the beginning of the frame, and after Day failed to hit it, the seven-time world champion potted a green as an extra red and then put away a black.
