Trainer Mick Price believes he has a solid country cups contender on his hands after Aeratus claimed the last race at Flemington on Saturday.

It was a popular finish to the card with the galloper continuing his brilliant run of form under jockey Glen Boss to defeat roughy Prizum ($41) and Chilli Express ($9).

Aeratus has progressed from wins in lowly rating races at the start of the preparation to now be an open handicapper with six wins from 11 career starts.

“He's been the revelation of the stable,” Boss said.

“Mick put the blinkers on and its amazing what a difference it can make. They’ve turned him into a racing machine.

“He’s not the best horse around but I love the way he applies himself to what he does.”

Price will spell the galloper as planned despite Saturday’s win and is eyeballing the Victorian country cups circuit with the son of Magnus.

“The owner really understands horses and knows the benefit of what spelling a horse for the best part of their three-year-old year can do for a horse,” Price said.

“He’s up to open handicaps now. I don’t think he is a spring carnival horse but there’s plenty of good country cups races like the listed Kilmore and Seymour Cups that we can target with him now.” (Racing Network)
