Ronnie O'Sullivan has reached his ninth World Championship semi-final after a 13-10 win over Neil Robertson at the Crucible.
In a thrilling encounter, the three-time winner found himself 5-3 down after Tuesday's narrow first session.
O'Sullivan then won six consecutive frames at the start of Wednesday's opening session to put him in control before 2008 winner Robertson claimed the final two frames.
However, the Englishman was again in control when they resumed play and he was able to edge out the Australian to book his place in the final four.
