Captain Cody won the great Scottish citizen in Air, but the race was overwhelmed by the death of two horses.
The winner is 9-1 by one Laili Molins from his colleague at Klac Kent.
The result is the Irish coach, who fell in Grand Nationalism in Aintree a week ago with Nick Rockett, moved away from the second British championship.
However, MacDermott, who was trained in 2024 and Kniphand, has suffered from fatal injuries. KnipHand, which was trained by Nigel Twiston-Davies, was one of the many falls in the race, while MacDermott was pulled.
