Prepared by the Hayes / Dabernig training partnership, the daughter of Fastnet Rock was an eye-catching debut winner at Moonee Valley on December 9 and was even better this time around.
Partnered again by Craig Williams, Catchy raced up on the pace to park just behind the leaders and skipped way in the straight to win the 1100 metre dash by more than two lengths over a field of colts and geldings.
"She jumped nice and got into her rhythm," said Williams, who has compared Catchy to his former favourite filly Miss Finland.
"Once she got balanced up she was very dominant.
"I really like her, she has a lot more in store."
A $220,000 Inglis Australian Easter purchase from the Coolmore draft for Robert Crabtree's Dorrington Farm, Catchy will now have bigger fish to fry.
"It was great to see her run well here at Caulfield and see the improvement in her," said co-trainer Ben Hayes.
"She'll go the Prelude next which is two weeks before the Blue Diamond. We'll just give her a little freshen up and then into the Prelude."
Foaled and raised at Coolmore, she is the fourth winner from four foals to race from Group II winner Cats Whisker.
Coolmore will offer the full sister to Catchy at Magic Millions next month as Lot 703 (pictured below) and Cats Whisker produced another colt by Fastnet Rock in 2016.
