Mango Tango finished with a flourish to win on her British debut for Archie Watson in the Betway Casino Conditions Stakes at Lingfield, as Toast Of New York claimed a close third.
Trained in France by Pascal Bary in her younger days, the winner had a fruitful spell in Qatar before joining the upwardly-mobile Watson.
Toast Of New York, runner-up in the Breeders’ Cup Classic in 2014 and nursed back into competitive action by Jamie Osborne, set out to make all.
Adam Kirby made a bold bid for home some way out on the seven-year-old, who was last seen finishing fourth over a mile and six furlongs at the Breeders’ Cup meeting.
Having won the race 12 months ago on his comeback, Toast Of New York was sent off the 7-4 favourite to repeat the feat but was challenged on either side by Scarlet Dragon and the Eddie Greatrex-ridden Mango Tango.
The latter, who was a 13-2 shot, beat Scarlet Dragon by a head, with Toast Of New York narrowly behind in third.
Watson said: “Mango Tango is a very talented filly and had some very good form in France.
“We were second in this race last year with Petite Jack, who went on to win the Listed Quebec Stakes. He was moved away from us during the summer, and I wanted a horse for the middle distance division of the All-Weather Championships.
“All the credit must go to Tom Biggs, who buys all of my horses. He found Mango Tango in Qatar and, although it is hard to get a line on the form, she had been winning races out there.
“It was a big job shipping her home, for new owners in the yard, and I am delighted she has won today because I am sure she will progress plenty.
“She was second in the Prix de Pomone, which is a Group Two over a mile and a four furlongs, but I think 10 furlongs is her trip.
“There is a great series of 10-furlong races here during the All-Weather Championships. We will go to the Quebec Stakes (on December 22) next and then you have races like the Winter Derby Trial, Winter Derby and Magnolia Stakes at Kempton before Finals Day.”
