Aidan O’Brien is eager to see how Rostropovich and Kenya fare as the pair step up in trip to an extended 10 furlongs in the Homeserve Dee Stakes at Chester on Thursday.
Kenya was a Group Three winner as a juvenile but finished a 13-length third to stablemate Gustav Klimt over seven furlongs on his return last month, while Rostropovich claimed the Futurity Stakes last season as well as finishing third in the National Stakes.
He was fourth in a Longchamp Group Three over a mile on his return and is the pick of Ryan Moore, who rode Cliffs Of Moher to win the race for the Ballydoyle team last year. Kenya will be ridden by Donnacha O’Brien.
O’Brien told At The Races: “Both are stepping up in trip. We didn’t want to step them up too far. It will be good experience for them.
“Rostropovich ran well in a Guineas trial in Longchamp and Kenya ran in Leopardstown over seven furlongs on very bad ground.
“(We’re) looking forward to getting them started and (we’ll) see.”
Another colt taking a steep hike in trip is the Tom Dascombe-trained Finniston Farm, who was second in the seven-furlong Free Handicap at Newmarket on his seasonal bow.
Dascombe said: “He’s stepping up in trip. He’s never run round a bend before so it will be a new experience for him.
“We’ve got to find out where we are with theses horses.
“I think he’ll enjoy the step up in trip.”
My Lord And Master represents William Haggas after narrowly losing out in the Blue Riband Trial at Epsom last month, while King’s Proctor, Rastrelli and Shakour complete the seven-strong field.
