Friday framewatch

Ronnie O'Sullivan produced an awesome display in the second session of his semi-final against Stephen Hendry as he stretched his lead to 13-3.

O'Sullivan won the first four frames of the afternoon in just 42 minutes before the mid-session interval.

The Englishman then came out after the break and won the next three before Hendry pinched the last.

But it was scant consolation for Hendry, with O'Sullivan needing just four more frames to reach the final.

The first part of the afternoon saw "The Rocket" produce near-perfect snooker.

He made breaks of 81, 92 , 52 and 117 - his 12th century of the tournament - while Hendry was a virtual spectator.

Although O'Sullivan was not quite as dominant after the interval, he still was able to wrap up three frames in relatively quick time.

Hendry had never suffered a session whitewash at the Crucible before, and even though he edged the last to avoid that ignominy he will still need a miraclulous comeback to reach the final.
