"As soon as he put a length on them he just pricked his ears and idled down.
"He is an exciting horse, just a real sprinter and he does it with ease.
"He has run 45 (seconds) for his last half-mile (800m) and won on his ear. That is impressive work."
McEvoy said Sepoy switched off in the lead and had the race won at the top of the straight.
"He put it to bed within 50 yards once we straightened up," McEvoy said. "It is fair to say if something challenges there is more in the locker."
One day he would like to ride Sepoy off the pace to see him concentrate better at the end of a race but it was hard to give up taking a position on the pace when he does it so easily.
And the news doesn't get any better for potential rivals with Snowden predicting improvement in Sepoy for his next start in the Group Two Danehill Stakes (1200m) at Flemington on September 3.
"It is three weeks to the Danehill and I would think he would better again."
Snowden said he was mindful but not worried about the doubters who had expressed concern that Sepoy's 14-week preparation for the spring had been too long.
"I was very confident. It was just everyone else around me was trying to put the cold water on him," Snowden said.
"He won today just how I wanted to see him win.
"He thrives in the stable environment and just for a change we brought him to Melbourne the last three weeks just to top him off."
Snowden said Sepoy was keen behind the gates but that was to be expected as he had not raced since April when he won the Golden Slipper Stakes.
"It was the first time I have seen him get a bit jog-jogging behind the gate but that was just freshness, just newness," Snowden said.
Sepoy has won six of his seven starts and is undefeated in four runs at Caulfield where he won the Blue Diamond Stakes in the autumn.
