Melbourne Cup aspirant Galileo's Choice continued on the upgrade with victory in the Ballyroan Stakes at Leopardstown.
The Dermot Weld-trained six-year-old finished seventh to Cinders And Ashes in the Supreme Novices' Hurdle at Cheltenham in March and returned to the flat with a Listed race win at Leopardstown in July.
Stepped up to Group Thee company, the gelding travelled smoothly in mid-division through the early stages before making his bid off the home turn under Pat Smullen.
The move proved a decisive one and he had a length and a half in hand over Massiyn on the line.
Paddy Power and Stan James quote Galileo's Choice at 25-1 for the Melbourne Cup while TAB Sportsbet has him at 50-1.
Weld will first look at the Irish St Leger on September 15.
"It was a very good performance," Weld said.
"I'm considering the Irish St Leger for him and he'll be entered in the Melbourne Cup.
"There was a lot of very good horses in the race. It was a proper race, full of Derby winners and Derby-placed horses."
