Connections will consider a range of top-level options for I'm A Dreamer after the filly recorded a landmark success in the Beverly D Stakes at Arlington under Hayley Turner.

The David Simcock-trained five-year-old took over in the stretch and just had enough in the tank to hold the fast-finishing Marketing Mix by a head.

In October, the daughter of Noverre had been beaten by the same distance in the E.P Taylor Stakes at Woodbine in Canada with William Buick in the saddle.

Buick, however, was required by John Gosden for Joviality, who ran a fine race in third.

Turner was making history in Chicago as the first woman rider to win the race, having last year performed a similar feat when standing in for Buick as Simcock's Dream Ahead won the July Cup at Newmarket.

The victory automatically qualifies I'm A Dreamer for the Breeders' Cup Filly And Mare Turf at Santa Anita as part of the 'win and you're in' series.

Simcock said: "Hayley has won on the filly twice in her career now and also substituted for me last year in the July Cup.

"She is normally William's ride, but he had to ride for Mr Gosden and I put some names to the owner and his choice was Hayley - she's a very capable jockey.

"She travelled really strong, there wasn't a massive amount of pace early on, but we half expected that. She ran quite fresh and picked up really well.

"We have loads of options now. It's which route we want to take. Yellow Ribbon and Breeders' Cup is one route or Champions Day and Prix de l'Opera, there are lots of options.

"This will be her last season racing."

Turner said: "I can't believe it. Thanks again to David Simcock and his team, because I haven't had a lot to do with the filly.

"So credit to them really - it was very kind of them to just put me on board.

"When you have a horse with that kind of ability, it makes your job a lot easier. I thought she had a good chance, she had a lovely attitude before the race and she's run well (in North America) before.

"It's such a nice atmosphere here, really casual and friendly. The reception was amazing."
