Q: Question: What was the name of the jockey that rode the favored horse that Fenomeno was considered less fancied against? Passage:On his three-year-old debut, Fenomeno won a minor race over 200 metres at Tokyo on 29 January, beating the subsequent Tenno Sho (autumn) winner Spielberg into second place. He then stepped up in class for the Yayoi Sho (a trial for the Satsuki Sho) at Nakayama and finished sixth of the fifteen runners behind Cosmo Ozora. On 28 April the colt was moved up in distance for the Grade 2 Aoba Sho over 2400 metres at Tokyo and started the 1.1/1 favourite against sixteen opponents. Ridden by Masayoshi Ebina, who became his regular jockey, he recorded his first important success as he came home two and a half lengths clear of Etendard. The colt was then moved into the highest class to contest the Tokyo Yushun on 27 May in which he started at odds of 13.6/1. He was less fancied than Sunday Racing's other two runners World Ace (the favourite) and Deep Brillante with the best of the other runners appearing to be Gold Ship and Grandezza (Spring Stakes). Coming from well off the pace, Fenomeno produced a strong, sustained run on the outside, but just failed to overhaul Deep Brillante and was beaten a nose in a photo finish.
