Sackville Set For Clonmel On Sunday Frances Crowley's top chaser Sackville is set to make his long-awaited reappearance in the Morris Oil Chase at Clonmel on Sunday.The nine-year-old was favourite for the Cheltenham Gold Cup this time last year, but he completely lost his form in the second half of the season. But Crowley is optimistic that he is back to his former self.She said on Tuesday: 'Sackville is in good form and he probably runs on Sunday although I don't yet know who will ride him.' Heavy rain is forecast but Clonmel racecourse manager Jerry Desmond is confident that racing will go ahead: 'Although we will get further rain today, there are only showers forecast for the remainder of the week so we don't have any worries.'Naas manager Margaret McGuiness, said regarding Saturday's scheduled meeting: 'We expect an inch of rain between now and Saturday but the prospects are good. It was only a small section of the course that knocked out our last meeting. It was on the bend past the stands and we have covered the area with tarpaulins.'
