Miss Promiscuity became the 8th stakes winner for Magnus with a Group 3 breakthrough in the Sir John Monash Stakes (1100m) at Caulfield.

A homebred for Dorrington Park owner Rob Crabtree, she overcame an outside gate to settle outside the leaders and maintained a wide course in the straight for an authoritative victory on Saturday.

“She began so well and I knew the favourite (Lord Of The Sky) had missed the start,” jockey Dwayne Dunn revealed.  “She travelled around the bend really well and gave a super kick.  “She’s capable of winning even better races now she has that black-type win.”

Co-trainer Tom Dabernig wants to set Miss Promiscuity for the G3 Bletchingly Stakes (1200m) at Caulfield in a fortnight rather than thinking about retirement.  “We would like her to race on instead of going to stud,” he said.  “Now that she’s a Group winner, it would probably be tempting for Rob but there’s some lovely races for her through the spring.”

Miss Promiscuity (4m Magnus – Zipstream by Distant Music) had won her maiden as a spring three year-old at Dunkeld and run Group 3 placings in the Typhoon Tracy Stakes at Moonee Valley and Proud Miss Stakes at Morphettville.

Her dam Zipstream is a half-sister to the stakes winners Amtrak (Flying Spur) and Furio (Testa Rossa).  The mare has a yearling colt by Stratum, a weanling colt by Helmet and she was bred back to Magnus last year.

Miss Promiscuity carries Crabtree’s red and white checked colours as did Magnus during a career highlighted by a Group 1 victory in the AJC Galaxy.

Eliza Park International will stand Magnus for a $17,600 (inc gst) fee at this year.
