KARACHI: Pakistan failed to qualify for the semi-finals of the men's hockey tournament at the London Olympics after a 7-0 thrashing at the hands of world champions Australia.

Australia started the attack as soon as the first half started and scored the opening goal in the fourth minute as Liam Young scored through a rebound off a penalty corner. One minute later, Mark Knowles doubled the score from a penalty corner.

Pakistan seemed to make an effort after the first five minutes but could not create any concrete chances. Goalkeeper Imran Shah was kept busy as Australia netted their third and fourth goals in the first half through Christopher Ciriello - one coming through a penalty corner.

The second half saw an even more listless performance from the Greenshirts which Australia took full advantage of.  Russel Ford, Jamie Dwyer and Glenn Turner scored a goal each to complete the 7-0 rout and confirmed their top spot in Pool A along with a semi-final berth.

Pakistan held Spain to a 1-1 draw followed by a 2-0 win against Argentina, a 4-1 loss against Great Britain and edged past South Africa 5-4.
