(CNN) -- Shane Watson smashed the biggest six of the tournament as three-time defending champions Australia swept aside Canada Wednesday to move to the top of cricket's World Cup Group A.
All-rounder Watson, who was named man-of-the-match, struck a 104 meter blow as Australia beat their plucky opponents by seven wickets with 15 overs to spare in Bangalore.
Watson (94) and Brad Haddin (88) shared an Australian record for the first wicket at a World Cup of 183 as their side chased 211 for victory.
They are unbeaten in five games and play Pakistan in a heavyweight clash Saturday which could decide who tops the group.
"We haven't been fully tested yet, but we will be by Pakistan in Colombo and we are looking forward to it," Australian captain Ricky Ponting told Sky Sports.
Earlier, India-born Hiral Patel gave Canada a boost with a career-best 54 as they took the attack to Australia.
They were prospering at 150 for two wickets but promptly lost five wickets for 19 runs with Brett Lee ending with four wickets for 46.
Australia, who are unbeaten in 34 matches at the World Cup since 1999, easily knocked off the required runs, but had a brief hiccup towards the end as both Watson and Haddin went in quick succession.
Ponting also failed with the bat again before victory was sealed.
Meanwhile, their arch-rivals England are struggling to qualify from Group B and face a must-win match against West Indies in Chennai Thursday.
England have already been shocked by Ireland and Bangladesh and reports suggested out of form paceman James Anderson would be dropped for the key clash.
However, he could be reprieved as Ajmal Shahzad has gone down with a stomach problem, which has also hit captain Andrew Strauss and spinner Graeme Swann.
