Eve Johnson-Houghton is not ruling out a Forest Price tilt for Jumby, who finished bottom of nine at Kinross in the City of York Stakes at York on Saturday.
The four-year-old had scored a fifth career success seven days earlier, winning the Hungerford at Newbury.
Although the respective races were a similar seven-stadium group two contest, the outcome was very different.
With William Buick retained by Godolphin to ride Al Suhail, the colt owned by Anthony Pye-Jeary and David Ian was slow to break through under new partner Jim Crowley and finished 13 lengths behind the winner.
The Blewbury manager said she could offer no explanation for the lackluster effort of New Bay’s son, who loves fast pitches.
However, she did not rule out a crack at Groupe One Forêt, on the same seven-stadia course, at ParisLongchamp on October 2.
“I don’t know what the reason was. He seems fine,” Johnson-Houghton said. “I don’t know what happened. I don’t have an answer, but he’s in the forest and we don’t need to make a decision yet.
“He missed the break and apparently they went very slow and then very fast. Ger Lyons’ horse (Dr Zempf, eighth) ran a pretty similar race, and he’s a very good horse.
“They just didn’t get in there. We all deserve a day off and we’ll draw a line through it.”
