[5] Apart from Rose Bowl, Roseliere also produced the King George VI and Queen Elizabeth Stakes winner Ile de Bourbon.
[7] Rose Bowl began her three-year-old season at Newmarket in the seven furlong Nell Gwyn Stakes, a trial race for the 1000 Guineas.
[2] On 1 May, over the Rowley Mile course at Newmarket, Rose Bowl again started 7/4 favourite, but finished fourth behind Nocturnal Spree, Girl Friend and Joking Apart.
[9] Piggott had been unable to obtain a clear run on the favourite, who was boxed in on the rail and Rose Bowl appeared to have been an unlucky loser.
[10] Rose Bowl returned to racing in the Group One Sussex Stakes over one mile at Goodwood in which she was matched against colts and older horses.
Ridden again by Piggott she finished second in a three-way photo-finish, a "fast-diminishing"[11] neck behind the 2000 Guineas winner Bolkonski and a short-head in front of the leading sprinter Lianga.
Ridden again by Carson, she won the race from Allez France with the Prix d'Ispahan winner Ramirez in third and Star Appeal unplaced.
In autumn she returned to form to beat Ricco Boy and Dominion in the Queen Elizabeth II Stakes, becoming the second horse, after Brigadier Gerard to win the race twice.
