Twice stakes-placed, the 5-year-old Extreme Choice mare Extremist broke through for a valuable stakes success in Saturday’s Listed Channel 7 Keith Noud Quality (1200m) at Doomben.

Ridden by Robbie Dolan for Robert Heathcote, Extremist travelled sweetly on the outside of Zarastro. She gradually got the better of the I Am Invincible gelding to win by one and a quarter lengths.

A $35,000 purchase for Robert Heathcote Racing/Steve Morley Bloodstock from the Eureka Stud draft in Book 2 of the 2020 Magic Millions Gold Coast Yearling Sale, Extremist advances her record to six wins, five seconds and three thirds from 20 starts with earnings of $346,500.

“It’s very satisfying, she is a tough as they come,” stable representative Mel Sharpe said.

“Being by Extreme Choice she is a very valuable mare. We space her runs because she is not a huge mare. She can be a hot little girl.”

Extremist is the best of three winners from as many to race for the Johannesburg (USA) mare Rubinacci, who died in 2021.

A 7-time winner, Rubinacci was a $50,000 purchase for Harry McAlpine Bloodstock at the 2018 Inglis Australian Broodmare Sale and was a great-granddaughter of the VATC One Thousand Guineas and VRC Oaks Stakes winner Rom’s Stiletto.

Bred by Eureka Stud, Extremist is the 11th stakes-winner for Newgate Farm’s flagship sire Extreme Choice, who runs at 13.8% SW to runner.
