Melbourne Premier star Booker (Writte Tycoon ex Noondie) became the sixth individual Inglis graduate to win a Group 1 race in 2019 when successful in the Oakleigh Plate at Caulfield.
The 4YO mare secured her maiden Group 1, having won two other Stakes races previously, defying a wide barrier and little luck in running to win first-up from a spell.
Booker joins In Her Time (Oakleigh Plate), Manuel (Orr Stakes), Beat The Block (Centenary Sprint Cup), Enzo's lad (Telegraph Hcp) and Atyaab (Cape Derby) as Inglis graduates to win at the top level this year.
She also becomes the second consecutive Inglis graduate to win the Oakleigh Plate following Russian Revolution's success in 2018.
Booker, trained by Mathew Ellerton and Simon Zahra, was a $230,000 buy for Barry Griffiths from the 2016 Melbourne Premier Yearling Sale, where she was offered by Mill Park Stud.
"It's a fantastic result for the farm and a fantastic result for loyal clients of ours in Liz and Tony Freebairn and Bill Rigg,'' Mill Park's Chris Watson said.
"Booker was always an absolute powerhouse of a filly from day one. She was always going to be an early-running type, which she turned out to be, and to win a Group 1 so early in her career is amazing.''
