Century heads O'Brien Post trio The supplemented Century heads a three prong attack on Saturday's Racing Post Trophy at Doncaster for Aidan O'Brien. The son of Montjeu, who won his only start at the Curragh earlier in the month, will be joined by impressive Tipperary winner Buonarroti and the maiden Johann Strauss. Johnny Murtagh's Altruistic and Pat Shanahan's Dolce N Karama add further Irish interest. Richard Hannon will rely on Chief Barker after deciding to give the race a miss with National Stakes winner Toormore. The pair, who are both owned by Middleham Park Racing, boast unbeaten records with each juvenile winning three times already this season. However, it is thought the likely easy ground on Town Moor will suit Chief Barker, who beat subsequent Fillies' Mile winner Chriselliam last time time out, much more than previous Group One winner Toormore. "Doncaster have had more than 12 millimetres of rain this week, so inevitably the ground will be slow, so we have decided to run Chief Barker and not Toormore, who will now be put away until next year when he will have a Guineas preparation," the trainer told www.richardhannonracing.co.uk. "Toormore is all class but his speed would be blunted by soft ground, whereas Chief Barker, a good horse in his own right, is more the grinder so arguably better suited to the testing conditions." Roger Varian supplemented his Autumn Stakes winner Kingston Hill earlier in the week and he takes his chance. There were two other supplementary entries, the well-fancied Godolphin hope Pinzolo and Sir Michael Stoute's 11-length maiden winner Snow Sky. Aiming to keep the prize in the north of England are Mark Johnston's Royal Lodge runner-up Somewhat and Kevin Ryan's The Grey Gatsby.
