Melbourne Cup favourite Order Of St George has run out a comfortable winner of the Irish St Leger Trial Stakes for the second year running at the Curragh.

The Aidan O'Brien-trained four-year-old was sent off at 2-11 for Saturday's Group Three contest following his impressive Gold Cup triumph at Royal Ascot.

O'Brien indicated it would be a similar plan to last year as regards the immediate target for the winner.

"I'm delighted with that," O'Brien said.

"He was just ready to start back so I was a bit worried but he settled lovely and you'd have to be delighted.

"He'll come back here (Irish Leger) first and we'll take it a step at a time with him."

part-owned by Lloyd Williams, Order Of St George is at $11 for the Melbourne Cup ahead of Signoff at $15.
