Chris Waller will consider pitting Catkins against the stable's star mare Red Tracer in next Saturday's Group One Myer Classic after her strong victory at Moonee Valley on Saturday.

The tenacious and talented Catkins handled her first 1600m test with aplomb to take out the Group Three Eliza Park International Stakes, her second Group Three win in Melbourne this campaign along with two Group Two placings.

Waller already has Group One winner Red Tracer set to start a likely favourite in next Saturday's Myer Classic (1600m) at Flemington, but Catkins could also have earned her chance.

"You've got to consider it, for sure," Waller said.

"Ideally the (Group One) Coolmore Classic would be the race for her in the autumn.

"It's on her home track at Rosehill and is a handicap over 1500 metres. But we'll certainly have a think about Saturday."

Jockey Craig Newitt had Catkins ($9) just behind the speed and had to be patient coming to the home turn before a run presented itself along the rails.

Under a big weight of 59kg, Catkins sprinted strongly along the fence to defeat Cameo ($8) by a length with favourite Lake Sententia ($4.20), which made a long run from about the 700m mark, another half length away third.

"I couldn't believe how well she quickened with the big weight," Waller said.

"She obviously gets the mile no problems."

Waller said Catkins' record of eight wins and five minor placings from 16 starts showed her competitiveness and will to win.

"Any horse that does that is a good horse," he said.
