Sean O'Keefe paid tribute to his friend Michael O'Sullivan after winning the Brown Advisory Novices' Chase aboard Lecky Watson at the Cheltenham Festival this afternoon. The 20/1 outsider was unfancied heading into the race but capitalised on a blunder of a performance from hot-favourite Ballyburn to take the win, a victory which O'Keefe says O'Sullivan always anticipated. Speaking to ITV after the race, O'Keefe paid tribute to the late O'Sullivan, who tragically passed away last month after a fall at Thurles. "Michael O'Sullivan was a big fan of this horse, he said he'd always win a race, a big race in fairness to him," said O'Keefe. "He stayed with us in the house here at Cheltenham the last few years as well. "He's missing from there this year, but in fairness he was a very good friend and we will always miss him."
