Nahoodh, ridden by Frankie Dettori, won the Group One Falmouth Stakes at Newmarket on Wednesday.

The 10-1 shot, having just her second run for Mark Johnston since leaving Mick Channon, flew up the hill to win by three-quarters of a length.

John Gosden's Infallible started well but could not match Nahoodh's pace and finished second ahead of pre-race favourite Heaven Sent and Seachange.

The stewards called an inquiry but the placings remained unaltered.

Johnston has had a relatively quiet season by his own high standards but was delighted with the display of his new arrival in the one-mile race.
