Joseph O'Brien completed a first and last race double at Killarney, as his Cornelius Sulla took the concluding Jim Ryan Racecourse Services (Pro/Am) Flat Race (O'Brien won the opener with Le Richebourg .

Placed on his last three starts, the son of Soldier Of Fortune was sent off the well-backed 11/4 favourite (from 4's) today in first time blinkers.

Sent straight to the front by Sarah O'Brien, he made all, keeping on well when ridden from two furlongs out, going on to score by four lengths.

Newcomer The Princetonian couldn't reel in the winner, and had to settle for second under Donal McInerney for Jessica Harrington at 8/1.

Joseph O'Brien also saddled the third horse home, and that was Mischievious Max (20/1) who was nine lengths back under Tom Hamilton.

Sarah O'Brien said afterwards: "He did it well but is a bit lazy and the blinkers seemed to sharpen him up a bit.

"He has been running very well in some very good races and was second to Debuchet so has the form.

"We'll see how he is after that and decide where he goes next but there's no real plan."

While Joseph O'Brien was completing a double at Killarney, his father Aidan and brother Donnacha also combined for a double of their own at the Curragh.
