Treble for O'Brien at Naas Offer produced a smart front-running performance to land the spoils in the October Handicap at Naas for Aidan O'Brien. Seamie Heffernan's mount won the early battle for the lead, with One Cool Shabra, and had a healthy advantage turning for home in the 1m4f contest. The Montjeu gelding stayed on well in the closing stages to post a three-and-a-quarter length win at 10/1. Leroy Parker won the battle for second with Scots Gaelic finishing third. 3/1 favourite Diplomat was fourth. The winner, who had been Group 3 placed at the Curragh back in July, was making his handicap debut. "Like all the Montjeus he has loads of ability. He got left alone in front and quickened well from two down," said Heffernan afterwards. This winner brought up a treble for Aidan O'Brien at Naas after wins for Francis Of Assisi and Snow Queen.
