Promising filly Exit, the highest-priced first crop yearling by Darley’s Bivouac sold last year, is off the mark with a decisive victory in Melbourne and her trainer Ciaron Maher and connections have cause to be aiming towards the spring with the rising three-year-old.

Exit, who was unplaced in the Group 2 Blue Diamond Prelude (F) at her only start in February, resumed with a 1.25-length win at Sandown on Wednesday over 1300m.

Godolphin’s homebred Bivouac filly Expulsion finished runner-up.

“She is a gorgeous filly with a good physical and a good brain. She was quite an expensive yearling and she's got a good pedigree, but that doesn't always account for everything,” jockey Blake Shinn told Racing.com.

“She had a good debut at her first run, although there's a ninth on the form guide, I thought her run had a lot of merit.

“She’s had a bit of time between preparations and had trialled up nice. She relaxed early and had the benefit of the big straight here today and that helped her.

“She got to the front, idled down and won with a bit in hand, so there is plenty of upside.”

Bred by Mill Park, Pamela Loxton and David Peacock and sold for $675,000 at the Magic Millions on the Gold Coast, such was the competition for Exit that under bidder and rival trainer Gerald Ryan immediately took a share in the Maher-purchased horse.

The latest of six first crop winners for Bivouac, who is also the sire of Silver Slipper winner Beiwacht, New Zealand Group 2 winner Intention and West Australian black type-winning filly Luana Miss, Exit is out of Lonhro mare Secretly Discreet, a winning half-sister to this season’s Group 2 Edward Manifold Stakes winner Too Darn Discreet.

Bivouac will stand for $55,000 (inc GST) this year.
