Prix de l'Opéra
In the Irish Oaks on 15 July, Light Shift was again matched against Peeping Fawn, who had won the Group One Pretty Polly Stakes in the interim. Light Shift, the 9/4 favourite despite her trainers concerns about the soft ground, raced just behind the leaders before taking the lead in the straight, but was soon overtaken by Peeping Fawn and finished second, beaten three and a half lengths. Three weeks later, Light Shift and Peeping Fawn met for a third time in the Nassau Stakes over ten furlongs at Goodwood. On this occasion, Light Shift made some progress in the straight, but could never reach the lead and finished third, five lengths behind the Irish filly and three and a half lengths behind the runner-up Mandesha. Following the race, Cecil suggested that the filly would be aimed at the Breeders' Cup. After a break of two months, Light Shift reappeared in the Prix de l'Opéra at Longchamp. She started the 11/4 favourite but finished sixth of the eleven runners behind Satwa Queen. Cecil said that the filly's "flat" performance may have been the result of a long and demanding season.
