World Snooker Championship 2018: Williams leads as Jones exits
Mark Williams has a two frame advantage over his opponent Robert Milkins at the end of the first session of the World Snooker Championships.
The two-time world champion was level at 3-3 with qualifier Milkins, before taking the final two frames at The Crucible.
Williams' fellow Welshman Jamie Jones was comfortably beaten 13-5 by Kyren Wilson earlier in the day.
Meanwhile there was a shock exit for five-time winner Ronnie O'Sullivan.
He lost 13-9 to Ali Carter in an ill-tempered match.
