Prix de l'Opéra
In May 2012, Izzi Top won the Dahlia Stakes at Newmarket and the Middleton Stakes at York in May. In July she was sent to Ireland to contest the Group One Pretty Polly Stakes at the Curragh. She won her fourth consecutive Group Race comfortably by one and a quarter lengths from the odds-on favourite Sapphire. On 4 August at Goodwood Racecourse, Izzi Top started favourite for the Group One Nassau Stakes but was badly hampered in the final furlong and finished sixth of the eight runners behind her three-year-old stable companion The Fugue. Two weeks after her run at Goodwood, Izzi Top finished second to Snow Fairy in the Prix Jean Romanet at Deauville Racecourse, but was later awarded first place when the winner failed a post-race test. On her final appearance, Izzi Top finished second to Ridasiyna when favourite for the Prix de l'Opéra.
