PALM BEACH GARDENS, Fla. — Rory McIlroy is 18 holes away from his first PGA Tour victory in 18 months, a chance to show the world he is back on his game.That's not the way McIlroy views the final round at the Honda Classic.McIlroy started strong, avoided a big number with a brilliant bogey in the middle and took on the wind and water on the 16th hole for one final birdie Saturday that gave him a 1-under 69 in the toughest conditions and a two-shot lead over Russell Henley at PGA National.The 24-year-old from Northern Ireland has come to expect this kind of performance.He finished one shot behind in Abu Dhabi. He played in the final group in Dubai, where nothing went well in the final round. And here is again, making key shots and big putt to keep his nose in front in the Honda Classic."I've been building and building toward getting my game to a level where I feel it should be," he said.
