Rough ride for Ronnie O'Sullivan at The Masters

Five-time champion Ronnie O'Sullivan marked his return to major tournament action with a battling 6-5 victory over Mark Williams in the first round of the Masters at Alexandra Palace in London.

The 40-year-old had taken some time away from snooker following the World Championship in April, where he lost in the quarter-finals to Stuart Bingham who went on to win the tournament at the Crucible.
