Calgary Bay has reserved some of his best performances for Town Moor and Saturday was no different as the nine-year-old did defied a welter burden to land the Sky Bet Chase at Doncaster.
Henrietta Knight's charge was seen to great effect as the in-form Dominic Elsworth gave the 12-1 shot a patient ride, before running out a deserving two-and-half length winner with Shakalakaboomboom (6-1) chasing him home while 22-1 outsider Fruity O'Rooney did well to complete the 1-2-3 after Jamie Moore's saddle slipped two from home.
"I was really pleased with him and it's a fine weight-carrying performance," Elsworth said.
"He's a really big horse and luckily he can carry it. It's not for me to say he should go for the National, but obviously he jumps very well."
A delighted Knight added: "With that big weight he had to be patient with him. He likes it here and won his first chase on this track.
"The Grand National is the aim. I think he'll go straight to Aintree now. He deserves a rest now and he's been out in the field with Somersby most of the week.
"We always wondered if he really stays three miles, but he has always loved this track and he was going to run in this race last year, but it was called off. I looked at all the last winners and nothing had won with that weight."
