Captain Cody gained with an ice-cool journey from British champion jockey Harry Cobden.
Cobden, in solely his second journey for Mullins, who saddled the primary three at Aintree final week, exuded confidence on the winner.
“To journey for a coach like him is unbelievable. He did not give me any directions,” he stated.
Our Energy was third forward of Grozni, with Rock My Approach in fifth place.
Regardless of being odds-on favorite to win the trainers’ title in a fortnight, Mullins is taking nothing as a right in his battle with Dan Skelton.
“Dan will not be standing nonetheless so he’ll most likely win it, and if he does he’ll really feel like he is gained a correct title,” Mullins stated.
Solely eight of the 23 runners completed the Scottish Nationwide, and marketing campaign group Animal Rising stated the race was “nothing in need of carnage”.
Activists had criticised the game following the death of Celebre D’Allen after the Grand Nationwide at Aintree.
In the meantime on Saturday, jockey Harry Atkins sustained a knee damage after falling on Snipe and was stood down for the day.
