Judd Trump takes lead against battling Ronnie O'Sullivan in World Grand Prix final

Ronnie O'Sullivan clawed his way back into contention after a torrid opening session of the World Grand Prix final against Judd Trump in Leicester.

O'Sullivan once again failed to punish his opponent for a pair of misses in the third frame, going in-off during an attempted safety which enabled Trump to chisel out the points required to extend his lead.
