Nico de Boinville gave Lough Derg Spirit (7-4) a positive ride from the front to claim the Sky Bet Supreme Scottish Trial Novices' Hurdle at Musselburgh.De Boinville, who only returned from three months out through injury on Friday, stole a few lengths on the turn for home on the Nicky Henderson-trained five-year-old.That move proved decisive as Lough Derg Spirit kept up the gallop to hold the 10-11 favourite Peter The Mayo Man by two and a half lengths.De Boinville said: "I'd seen there was a bit of a golden highway from the front round here, so I thought we may as well be positive."We had to find a pound somewhere to beat Peter The Mayo Man, so that's what we did."He's slick at his hurdles and he came out of my hands at a couple of them. He is good and knows what he's doing."Henderson said: "I just thought after Burbank in the first race the track was sharp enough. His hurdling is very slick so I said to Nico we had to grab this a bit and be very positive. He gave him a good ride."It was good because you have to be sharp round here."It was a good performance, but we'll have a think about what we do next. He's still a baby and his life's in front of him. We'll see what the owners want to do."
