The drop in grade proved to be an advantage for Fifth Ave, as she gave a good performance to earn her victory, under the guidance of Sophie Doyle, in the Digibet.com Nursery at Kempton.
Always in touch throughout the race, Doyle moved her mount into the lead over one furlong out, pushing out the filly trained by Jamie Osborne, to stay on strongly inside final furlong for a classy one and three quarter length victory over runner up Hortensia.
"She had a very busy first part of the season and then we gave her a six-week break and this is her first run back", said Osborne.
"I always thought 77 was a mark she could win off, so it was a surprise to see her as the outsider.
"She is on Friday at Sandown and the five up the hill should suit her."
Trainer John Gosden followed up on his good run of late when Flower Fairy won the Olly Murs Live On Ladies Day Maiden Fillies' Stakes.
Jockey William Buick settled into third place, tracking the race leaders, moving into second place inside the last four furlongs, pushed along to hit the front just within the final two furlongs, holding off the challenge by Wulfrida in the last furlong to stay on well for a comfortable victory by two lengths.
Taking his win count to 58 for the year up to now, Flower Fairy was awarding Gosden with his twelfth victory in just less than a fortnight.
Increasing her workload when it counted was Sweet Clementine providing race goers with an exciting end to the Ladies Day September 4th Handicap.
Jockey Shane Kelly held up at the rear of the field, switched left over two furlongs out, giving a strong run from over one furlong, stayed on well under great pressure within the last furlong to get ahead in the last stride defeating Red Somerset and by just a nose.
