Logician Warranted favouritism from the William Hill St Leger.
Sent off as the 5-6 favourite by Town Moor punters, they barely had a minute’s perspiration as Dettori delivered his struggle in isolation up the stands’ side.
As Logician left his movement, sir Dragonet appeared to be proceeding towards the middle of the track but he had no response to the winner kick and he dropped from the framework late .
Mark Johnston coached the home as Sir Ron Priestley beat Nayef Road for the spot.
But this was about Logician, who won the contest in a course-record time, Dettori, who continued his impressive season with a Leger triumph, Gosden, who had been winning his fifth Leger, and sire Frankel, whose progeny have won two Classics this season.
