Westover trainer Ralph Beckett said: "There was nothing that you and I couldn't see. They didn't go on as we thought they would and it didn't happen for us."
Oaks second Emily Upjohn pulled hard and trailed in last, a further seven lengths behind her fellow three-year-old. Her rider Frankie Dettori said: “The trip was too far today at that pace."
James Doyle, who rode Mishriff for the first time after David Egan and owner Prince Faisal recently parted company, said: "What happened at the start obviously didn't help but we were going downhill, so I was able to cruise up.
"I was able to get up to them but they kept the pedal down and I was never able to properly fill up. The trip has ultimately been shown to be a bit far."
