Efforia has not faced a serious test in two starts in Japan this year, the leading reason the colt is an odds-on favorite for Sunday’s Grade 1 Japanese Derby at Tokyo Racecourse.
Unbeaten in four starts, Efforia won the first leg of the Japanese Triple Crown – the 2000 Guineas at 1 1/4 miles – by three lengths over Titleholder at Nakayama Racecourse on April 18. Efforia won his stakes debut in a Grade 3 race at 1 1/8 miles by 2 1/2 lengths over Victipharus at Tokyo Racecourse on Feb. 14.
