Paul Casey produced a stunning five-under-par final round to secure victory at the Irish Open on Sunday. The Englishman, who was tied for fourth overnight, hit five birdies and an eagle in tough conditions at Carton House as he swept aside long-time leader Joost Luiten to card a final-day 67 and claim the title by three shots. In driving rain and strong winds, Casey started the day four behind Luiten – although he took some time to get going as he opened with seven consecutive pars. However, a run of five birdies in six holes – kick-started at the par-five eighth – saw him charge up the leaderboard to give him a three-shot lead on 14 under, which was subsequently reduced to a one-shot advantage by his only bogeys of the day at the 15th and 16th. The 35-year-old headed down the par-five 18th with work still to do, but a good drive was followed by a solid second into the green before – needing a likely two putts for the title – he drained a stunning 45-foot eagle chance to claim his 12th European Tour victory, and his first in two-and-a-half years. There was little that Dutchman Luiten and fellow challenger Robert Rock could do to stop him, as they finished tied for second at 11 under after respective rounds of 74 and 71. Spainard Pablo Larrazabal was a shot further adrift in fourth on nine under after a closing 75. “It&aposs incredibly sweet. It’s been a while and when that putt went in half of it was relief and half of it was satisfaction,” said Casey. “What a grandstand finish – winning an Irish open is an absolute dream.” Brett Rumford was the best Australian after shooting a final-round 72 to finish with a share of 22nd.
