Geelong remain unbeaten after overcoming a slow start to brush aside St Kilda and record an impressive 21.10 (136) to 13.16 (94) AFL victory at Telstra Dome.

After trailing by seven points at the first change, the Cats piled on 13.9 to 6.4 in the next two quarters to run away with the game, looking every bit as good as during their dominant 2007 premiership season.

For the Saints, it was the second round in succession they have been wiped away after starting well.

Last round they led the Western Bulldogs by 37 points at the first change before going down by 38 points.

They led 4.7 to 4.0 at the first change, with the difference in the number of scoring shots reflecting their early dominance in the midfield, while the Cats made the most of their limited early chances.

But, after quarter time, the Cats took control.

Brownlow medallist Jimmy Bartel, Joel Corey, Gary Ablett and Cameron Ling lifted their workrate in the centre to set up three goals in two-and-a-half minutes early in the second term and catapult their side into the lead.

It would have been four in four minutes had Paul Chapman not hit the post soon after.

The Saints took the ball the length of the ground from the resulting kick-out to set up a goal to Justin Koschitzke, which levelled the scores.

But the Cats scored the next three to assert their dominance and head into halftime with a 16-point lead.

After St Kilda kicked the opening goal of the third term, Geelong piled on six straight to open up a 46-point lead and put the result beyond doubt.

That run included some impressive highlights - a strong mark by youngster Tom Hawkins against Matt Maguire, a superb pick-up and right-foot goal by Ling and a goal on the burst from speedster David Wojcinski after the Cats had whisked the ball from defence.

Geelong had winners all over the ground, with fullback Matthew Scarlett magnificent against Fraser Gehrig and Koschitzke as a regular source of attacking moves.

Half-forwards Steve Johnson (four goals) and James Kelly (two goals) were both constantly dangerous, while big men Cam Mooney and Hawkins were also threatening in attack.

For the Saints, Lenny Hayes worked hard throughout the match to be his side's best, with Leigh Montagna and Luke Ball also useful through the midfield.

Nick Riewoldt worked hard in attack, kicking three goals and giving several others off, while Sam Fisher provided some run out of defence.

The Saints were not helped by some injury problems, with Robert Harvey coming off with a quadricep injury in the first term and Xavier Clarke helped off after a clash with Cats ruckman Trent West in the second, although both later returned.
