Viscount Nelson continued his education with victory in the Listed Coolmore Hurricane Run Stakes.Beautifully bred by Giant's Causeway and out of Oaks winner Imagine, Aidan O'Brien's colt made slightly heavy weather of landing cramped odds as the 1-2 favourite.Johnny Murtagh was given a lead into the straight by Bobbyscot and while Viscount Nelson did not pick up immediately for pressure, a few taps with the persuader made him go about his job in a professional manner, going away at the finish to win by half a length.O'Brien said: "I'm delighted with that. He's like his mumand dad in that when he gets to the front he doesn't do a whole lot.He's a very good-moving horse and he absolutely hated that ground."We will step him up to Group company now. The Futurity Stakes at Fairyhouse at the end of the month is a possibility."Perfect Polly won a thrilling renewal of the Abergwaun Stakes under a fine ride from Fran Berry.Sent off the 2-1 second favourite, Berry got a fine tune out of the Efisio filly to deny Snaefell, the 7-4 market leader, by a neck.James Ryan's filly used to be trained in England by Jeremy Noseda and had already won at Listed level at Haydock.Ryan said: "We'll see how she comes out of the race before we make any plans for her."Ideally she needs six furlongs and she had a hard enough race there. She is a lovely filly and the lead pony is a great help to her."
