Canford Cliffs, who ended his 3-year-old season last July with three consecutive wins in Group 1 stakes, will be heavily favored in his 4-year-old debut in Saturday&rsquo;s Group 1 Lockinge Stakes at Newbury Racecourse, west of London.\r\nCanford Cliffs is part of a field of 10 in the $285,000 Lockinge Stakes, run on a straightaway mile.\r\nTrained by Richard Hannon, Canford Cliffs has not started since winning the Sussex Stakes for 3-year-olds at Goodwood last July. Canford Cliffs won the Sussex Stakes by a neck after a troubled start. Last spring, Canford Cliffs was third in the English 2000 Guineas and won the Irish 2000 Guineas and St. James&rsquo;s Palace Stakes at Royal Ascot.\r\nIn the Lockinge, Richard Hughes will ride Canford Cliffs, who is likely to be an odds-on favorite.\r\nHannon also starts the biggest threat to Canford Cliffs in Dick Turpin, who was second in the 2010 St. James&rsquo;s Palace Stakes and later won the Group 1 Prix Jean Prat in France. Dick Turpin, who will be ridden by Ryan Moore, has made one start this year, winning the Group 2 Sandown Mile on April 23.\r\nTwice Over, third behind Zenyatta in the 2009 Breeders&rsquo; Cup Classic at Santa Anita, makes his first start since a ninth-place finish in the Dubai World Cup at Meydan Racecourse in March. Trained by Henry Cecil, Twice Over was third in the 2009 Lockinge Stakes, his most recent start at a mile. Twice Over won the Group 1 Champion Stakes at Newmarket last October, his last start in England.\r\n◗ Joviality won her stakes debut in Wednesday&rsquo;s Group 3 Musidora Stakes at York, a race that trainer John Gosden said was a prep for the Group 1 French Oaks at Chantilly on June 12.\r\nJoviality won the Musidora Stakes over Barefoot Lady by a head, taking the lead in the final furlong of the race over 1 5/16 miles. Arizona Jewel, the 11-8 favorite, finished fourth, fading in deep stretch.\r\nJoviality, a British-bred filly by Cape Cross, was a maiden before the Musidora, having finished third and second in her first two starts.
