Power Blue set for Guineas Trial in spring: 'He will be a Guineas prospect' Robson De Aguiar saddled his first winner as a licenced trainer at Dundalk on Friday evening and gave an update on Group 1 Phoenix Stakes winner Power Blue who he now trains. He said: "We gave him a good break after his win the last time. "He was a little bit weak and we have given him time, and he has grown and got stronger. "Hopefully, he has improved from last season. "He will be a Guineas prospect. "We have never tried him to see if he stays a mile or not, but we will work on that. If he stays a mile, we go Guineas all the way. If not, we will keep him to six furlongs. "It could be Leopardstown for a Guineas Trial." De Aguiar assisted Adrian Murray in training the AMO Racing Limited horses before taking out a licence in his own name.
