Mind Your Biscuits came with a powerful late run to win the Dubai Golden Shaheen in a decisive fashion.
Incredibly, the success was the first as a trainer for Chad Summers, who took over the training from Robert Falcone Jnr who guided the horse to second in the Breeders' Cup Sprint last season.
Drawn widest of all in stall 14, Joel Rosario did not start his challenge until the home straight but he picked up impressively to win going away. Comicas was second for Godolphin with Morawij third.
Rosario said: "When I knew we had stall 14 I wasn't very happy and it wasn't the best race as I was a little wider than I wanted before the turn.
"He showed he was the best horse today. I'm so happy for Chad, he works really hard and I'm glad to have the opportunity to be here."
Summers said: "He went a little wider than planned, but at this point I don't care if he was touching the turf course.
"He's a remarkable horse and Joel Rosario is a remarkable rider, I'm thrilled for everybody involved.
"I'm very proud and we knew we were coming here in December so set up a game plan and it came true.
"Your heart is in your throat for a little while, but when you have a jockey like Joel everything is fine."
Second Summer came from the clouds to give Doug Watson victory in the Godolphin Mile, the opening event on the card.
Sharp Azteca appeared to have stolen the spoils under Edgard Zayas when he had a clear advantage with a furlong to run in the Group Two event, but he was treading water in the closing stages.
Pat Dobbs sensed an opportunity on Second Summer and along with the German challenger Ross, they were catching Sharp Azteca with every stride.
It was Second Summer who prevailed, with Sharp Azteca fading into third.
The favourite North America was in trouble from some way out and finished well beaten.
Watson said: "When I saw him coming, I knew he would finish well.
"I knew he had the class to do that but I wasn't sure if a mile would be too sharp for him.
"The speed was huge, though, and that suited him.
"We had been aiming at the World Cup, but when we heard Arrogate was coming and he was beaten in another race here, we took it easy and aimed for this."
Watson, celebrating a first success at the meeting, went on: "We were so disappointed with his last run after he'd run so well first time.
"We just didn't know how he would handle the conditions, but he came home so nicely.
"He has a bit of class about him, but we really weren't ready for that to happen today."
