Erratic O'Sullivan capitalises on Selby errors

Mark Selby let Ronnie O’Sullivan off the hook as an intriguing first session between two of snooker’s most potent potters was littered with mistakes and finished all square.

The Betfred.com World Championship quarter-final was expected to be a thriller following the superb Masters final which the pair contended in January, but it did not begin in the manner of that Wembley match, which Selby won 10-9 from 9-6 down.
