Runner-up twice at Group I level, the courageous Prompt Response finally broke through for a well-deserved win at the elite level in Saturday's $500,000 Group 1 Tatt's Tiara (1350m) at Doomben.
The Gai Waterhouse-Adrian Bott-trained mare was given a positive ride by Blake Shinn from an inside barrier, opening up a winning margin 250 metres out then holding on strongly to defeat the fast-finishing Shillelagh (Savabeel) by one and a quarter lengths with Super Cash (Written Tycoon) a half head back in third.
Second to Tycoon Tara in the same race last year, the 4yo daughter of Beneteau has rarely run a bad race since finishing second in the Group III Ottawa Stakes (1000m) at Flemington during the 2015 Melbourne spring carnival.
She won the Group II Emancipation Stakes at Rosehill in April before finishing second in both the Group 1 Coolmore Legacy (Queen of the Turf) to Alizee and Group II Dane Ripper Stakes to Invincibella.
"We decided to ride her aggressively and dictate the race to them. When Daysee Doom went around us to lead she had the run of the race," Bott told AAP.
"She is a top-class mare and now she has the extra statistic to show it.
"I would now like to train her as a purely speed horse and look at a place in The Everest (at Randwick on October 13). I think she would be up to that race."
Prompt Response advances her record to 6 wins, 10 seconds and 1 from 27 starts with earnings of $1,481,350.
A sister to 2014 Group III VRC Maribyrnong Plate winner Prompt Return, Prompt Response was foaled at Newgate Farm and later raised from a weanling at Newhaven Park. She is the fourth foal of the Exceed And Excel mare Prompt whose first two foals are the stakes-placed Diamond Glow (Bel Esprit) and the Hong Kong winner Mr Right (Statue Of Liberty).
Though she failed to place in three starts, Prompt is a daughter of the Desert Sun mare Amnesia a 5-time winner who placed in nine stakes races.
After slipping in 2014 and 2015, Prompt has a yearling colt by Horse Of The Year Dissident that was purchased by George Moore Bloodstock for $525,000 out of the Newgate Farm draft at the Magic Millions Gold Coast Sale.
Prompt has a weanling colt by Medaglia D'Oro (USA) and was bred back to Capitalist at Newgate Farm last spring.
Prompt Response becomes the second Group 1 winner for Beneteau after the Victorian Oaks winner Lasqueti Spirit.
A son of Redoute's Choice, Beneteau died in January 2013 having left 136 live foals from two crops.
