Prendergast & Rogers headline makers at Curragh Thirty-year-old Kildare trainer, Patrick Prendergast, enjoyed the biggest success of his fifteen win career when sending out Waterways to make all in a very fast time of 59.94 seconds in the Listed Isabel Morris Marble Hill Stakes under Niall McCullagh at the Curragh today.A ?10,000 yearling purchase, the daughter of Alhaarth was reversing course and distance form with the market-leader, Ba Foxtrot, and Prendergast sees her as a Royal Ascot contender after she triumphed by a length and a half. He commented, 'she is a lovely tough filly and she worked well during the week. I knew she had improved since her last outing and seeing as Ba Foxtrot was favourite and he only beat us a short head, we had to have a chance.'Meanwhile, Harry Rogers, who enjoyed many memorable days with Livadiya (placed at Group level), gained his first victory in the grade when Moon Unit took the Group 3 Greenlands Stakes.The rank outsider of the eleven-runner field at 20/1 for the Weatherbys Ireland-sponsored contest, Johnny Murtagh's mount got on top close home to beat well-backed favourite Moss Vale.Rogers said afterwards, 'she runs well fresh and after she got loose on the gallops six to eight weeks ago we backed off with her after she had got a cut on her shoulder.'
