There are a few shouts of 'Come on Ronnie' after Selby misses a yellow in the early stages of the fifth frame. But there is little for O'Sullivan to get excited about as he has to play safe.
It is a tense start to the second half of the first session, but Selby will not mind the pace slowing down a bit as O'Sullivan was in sensational form earlier on.
But there is still a long, long way to go. Remember, it is the man who gets to 18 frames first that will be lifting the trophy.
