KEEP following the formidable Frenchmen - that has to be the formula for the second event on tonight's Happy Valley equitrack meeting where Top Hat looks the one they all have to beat. Trainer Patrick Biancone has his team in brilliant form, sending out four doubles from the last five meetings, and jockey Gerald Mosse has never ridden better. Top Hat has winning course and distance form and comes into the race off a very promising barrier trial. The main danger looks to be Lawrie Fownes' Admirals Run who will be ideally suited by tonight's course and distance. He ran on really well over an inadequate trip last time when second to the speedy Prudent King. The gutsy Lucky Knight must be conceded a definite tierce claim on his courage alone. He has also been working well.
