World Squash Championships 2012: England's Nick Matthew in cruise control as Nicolas Mueller dispatched Matthew had one of the toughest opening matches of the top seeds but came through 11-8, 11-6, 11-4, against the world No 20, who struggled to cope with the Yorkshireman's variety. Matthew also looked to have allayed fears of a back injury sustained in his defeat to Ramy Ashour at last week's Hong Kong Open. That will be a major boost to Matthew, who is attempting to win the title for a third time in a row. Meanwhile, English qualifier Joe Lee, the world No 48, produced a fine display to beat Pakistan's Aamir Atlas Khan to reach the second round for the first time in his career. The Pakistani has had a dip in form in recent months and the 23 year-old from Walton-on-Thames exploited every avenue to set up a second round clash with Amr Shabana, Egypt's four-time world champion. "I am so happy," said Lee, who won a titanic second game 24-22 to win in straight games. That was one more incentive to get to the next round, just to have a chance to try and have a shot at him [Shabana]. James Willstrop, the world No 1, plays his second round match on Sunday against Canada's Shaun Delierre.
