Camelot heads Derby 24 Camelot remains one of 24 colts still engaged in the Investec Derby after the latest scratchings stage. Aidan O'Brien's representative has been a warm order for the June 2nd Classic at Epsom all winter, but shortened to odds-on with many bookmakers after his smooth performance in the 2000 Guineas. There were no surprise drop-outs, with Thursday's Dante Stakes winner Bonfire still engaged along with Lingfield Derby Trial winner Main Sequence. O'Brien has plenty of support for Camelot as he has kept in Astrology, Father Of Science, Imperial Monarch and Tower Rock. Sir Henry Cecil still has three potential runners in Wrotham Heath, Frankel's brother Noble Mission and Thomas Chippendale while Godolphin have decided to keep both Mariner's Cross and Dante flop Mandaean in the reckoning. There is one further option to supplement for the Derby at a cost of £75,000 on May 28th. Some 22 fillies remain in the Investec Oaks, including all of the leading market fancies. These are headed by John Gosden's impressive Musidora winner The Fugue and William Haggas' Vow, who took the Lingfield Oaks Trial. O'Brien's team can be drawn from Betterbetterbetter, Devotion, Kissed, Maybe, Twirl and Was.
