Gentildonna, the 2012 Japanese Horse of the Year, makes her first start of the year in that country in Sunday’s $2,834,639 Takarazuka Kinen at Hanshin Racecourse, a turf marathon with a strong field of older horses.Gentildonna won the 2012 Japanese Triple Crown for 3-year-old fillies and then beat males in the Japan Cup last November. In her only start this year, Gentildonna was second in the Sheema Classic in Dubai in March.The Grade 1 Takarazuka Kinen is run over about 1 3/8 miles on turf and is part of the Breeders’ Cup Win and You’re In program, offering a fees-paid berth for the winner to the BC Turf at Santa Anita on Nov. 2.Gentildonna is part of a field of 11 in the Takarazuka Kinen, challenged by Fenomeno and Gold Ship. Orfevre, second in the 2012 Prix de l’Arc de Triomphe and Japan Cup, is a notable absence, having been withdrawn after bleeding in a workout earlier this month.Fenomeno, a 4-year-old colt, was fifth in the Japan Cup last fall and won the Grade 1 Tenno Sho at Kyoto Racecourse on April 28. Gold Ship was fifth in the Tenno Sho, a loss that ended a four-race winning streak in Grade 1 and Grade 2 races in Japan since last September.
