Jinsha Lake provided Aidan and Joseph O'Brien with a double on the card (earlier won with Ivanovich Gorbatov as he took the concluding Pour Moi EBF Maiden.
The son of Galileo finished second on his debut over the course and distance last October and he was sent off the 11/8 favourite to go one place better today.
Settled behind the leaders he was ridden to challenge over two furlongs out and he hit the front a furlong and a half from home.
He kept on well from there, stretching clear to score by a length and a half at the line. Chenega Bay finished second under Colin Keane for Ger Lyons at 7/1 while Dawn Mirage (4/1) was a further half a length back in third under Wayne Lordan for David Wachman.
Joseph O'Brien said afterwards: "He had a nice run here last year. He was working nicely at home and was ready to start off.
"You'd imagine he'll get a bit further. He might pitch up in a handicap, we'll see what mark he gets. It'll either be a handicap or stakes race."
