I Love Me sprung a monster 50-1 shock on her debut in the £200,000 Tattersalls Millions Auction Trophy at Newmarket.
Trained by Andrew Balding, the Cape Cross filly made nearly every yard of the running under an understandably delighted Kirsty Milczarek.
The 11-4 favourite Sir Reginald, who brought some top-class form to the table, made up plenty of ground from the rear under Declan McDonogh but despite closing inside the final 100 yards there was still a length and a half between them at the line.
Clive Brittain's 33-1 hope Shafgaan was a further three-quarters of a length away in third.
Aidan O'Brien's Oracle and Richard Hannon's Auld Burns failed to make an impression.
Balding said: "It wasn't a total surprise as she was getting a lot of weight, but don't get me wrong, she's a very nice filly."
Mark Tompkins' Theola (7-1) sprinted away inside the final furlong to win the Investec Cesarewitch Trial.
A thorough stayer, she seemed revitalised by the first-time visor and was given a patient ride by Jimmy Quinn.
Johnny Murtagh appeared to have done everything right on Ed Dunlop's Red Cadeaux but the 11-4 favourite had no answer to the finishing kick of the impressive winner, who won going away by two and a quarter lengths.
"She sprinted clear today and I think the visor was a big help," said Tompkins.
"The trip is the thing, she needs every yard of two miles and when she can race over further she is in her element.
"The plan is to run her in the Cesarewitch if she gets in and Jimmy will stay on board because she will have a light weight and also he is unbeaten on her, he's won on her twice before.
"I just hope it doesn't rain."
Theola was cut to 14-1 from 25s by the sponsors for the totesport Cesarewitch on October 16.
"Theola has put up an impressive performance over the Cesarewitch course and distance and connections will be hoping for a repeat performance in four weeks' time," said totesport spokesman Andrew Griffiths.
