Wertheimer and Frere's Solow, just off the pace in third for most of the race, made his move in the final furlong to capture the QIPCO Queen Elizabeth II Stakes (Eng-I) Oct. 17 at Ascot.
With Maxime Guyon riding for trainer Freddie Head, Solow held off the fast-closing 3-year-old colt Belardo by three-quarters of a length in the about one-mile (1,600 meters) event. Gabrial was third while Integral, the lone mare in the field in nine, finished fourth.
The winner covered the distance in 1:41.92 on ground rated good to soft.
Gleneagles, who has been called a candidate for the Oct. 31 Breeders' Cup Classic (gr. I) at 1 1/4 miles on dirt, loomed a threat in the final eighth of a mile but flattened out to finish unplaced. However, his connections have not yet withdrawn his name from Breeders' Cup consideration. A decision is expected later in the week.
Solow, a 5-year-old Singspiel gelding out of the Highest Honor mare High Maintenance, won for the 12th time in 17 starts. Bred by his owners, he has now won nine in a row, including five consecutive group I events.
"He's very special," Head told Racing Post. "To be able to keep his form like that all through the year with all the traveling he has done makes him a very good, very special horse."
Gleneagles was on the fence for Saturday's race until race day because of concerns of the turf condition. Gleneagles missed fourth other races because of similar concerns.
Trainer Aidan O'Brien told Racing Post that in retrospect he shouldn't have run Gleneagles in the Queen Elizabeth.
"We had an eye on the Breeders' Cup Classic and if he was to go there he needed to run so we took a chance," O'Brien told the publication. "He is a fast-ground horse and a fast horse, and that's what we've always thought. We'll have to take him home and see how he is over the next couple of days before thinking about the Classic."
