O'Sullivan edges ahead of Carter

Ronnie O’Sullivan turned on the style just when he looked to be wobbling to stay ahead of Ali Carter in their Betfair World Championship second-round showdown.

A gripping middle session to the contest saw O’Sullivan struggle at times, especially with his long potting and safety play, but he bookended his afternoon in the Crucible with two breaks of 86 and finished 9-7 in front.
