Littler remained on course to become the first player to defend a World Championship crown in a decade when he cruised into the fourth round on Saturday night, hammering Mensur Suljovic 4-0. He produced his highest-ever average at Alexandra Palace and had a 71 per cent success rate on the double - stats that would have alarmed the rest of the field.
