Trained by John Gosden, the High Chaparral colt had earlier this campaign finished second in the King Edward VIII Stakes at Royal Ascot.
Going from the Bahrain Trophy to the final Classic of the season is a route Gosden took with 2011 Leger winner Masked Marvel.
Hugo Lascelles, racing manager for owner Lady Bamford, said: “Lady Bamford has had some nice staying three-year-olds recently and I feel Mr Singh has more improvement left in him than them at this stage.
“We liked the performance at Newmarket. He looked well, quickened well and pretty much dominated the race from start to finish.
“He has come out of it well and will go straight to the St Leger now.
“He will be stepping up in trip but that won’t be a problem.”
