Kurt Kitayama holds off McIlroy to win thrilling Arnold Palmer Invitational

• American earns maiden PGA Tour win in Florida
• Spieth, Hatton and Scheffler also in mix on dramatic final day

Nobody can claim Kurt Kitayama earned his maiden PGA Tour win the easy way. The Californian recovered from a triple bogey at the 9^th hole of his final round and held off the challenge of Rory McIlroy to prevail at the Arnold Palmer Invitational. For his efforts, $3.6m (2.99m) and high praise from an otherwise rueful McIlroy. It was a great back nine, it was great to be involved in," said McIlroy. I'm really happy for Kurt. He's been playing well for a while now and I'm happy to see him get his first win."

At the last, Kitayama, 30, rolled a glorious 48ft putt to within millimetres of the cup. McIlroy, watching on from the scoring area, knew his eight under par total - Harris English shared that aggregate - would be insufficient for a playoff. Kitayama's birdie two at the penultimate hole proved the key moment of a gripping finale. At one stage, not long before close of play, five golfers shared the lead at minus eight. Kitayama's fortitude prevailed.
