Rocket struggles to fire

Ronnie O’Sullivan was well below his best again as Graeme Dott fought back to level their 888.com World Championship semi-final at 6-6 at Sheffield’s Crucible Theatre.

O’Sullivan, who defeated Dott in the 2004 final, had been fortunate to eke out a 5-3 overnight lead after being guilty of several mistakes which were capitalised on by the gritty Dott.
