Bryony Frost produced one of the rides of her life to drive Frodon to an 18th career victory in a thrilling finish to the £110,000 Grade One Ladbrokes Champion Chase at Down Royal, Ulster on Saturday.
As the investigation into her 'bullying' complaint against Irish-born jockey Robbie Dunne rumbles on, Frost from Buckfastleigh rode a masterful front-running race.
Frodon, trained by Somerset's Paul Nicholls, beat the Gordon Elliott-trained Galvin by three-quarters of a length, with Cheltenham Gold Cup winner Minella Indo, ridden by Rachel Blackmore, third.
As her rivals closed with two fences of the three-mile test to go, it looked as if Frodon might be beaten.
But the nine-year-old's trademark determination and Frost's urging - it was her first ride in Ireland as a professional - enabled the pair to pull off a memorable victory.
It took Frodon's career prizemoney tally through the £1 million-mark and continued a remarkable partnership with the 26-year-old South Devon jockey.
"That was tough. What more can you say about him? It's just phenomenal," said Frost, who was under extra pressure as the arguments continue over the right way to resolve the 'Dunne Affair'.
The British Horseracing Authority's report backs Frost, who has received support from at least one other female jockey.
The Professional Jockeys' Association have called for the case against Dunne to be dropped, because the report was 'leaked' to the Sunday Times.
But Frost is also a PFA member, and the riders' 'union' is in danger of taking potentially dangerous sides in the case.
Meanwhile, Nicholls has confirmed that Frodon's next race will give the gelding and Frost a chance to win a second successive King George VI Chase at Kempton Park on Boxing Day.
