By Chris Dunham, PGATOUR.COM Nick Watney didn’t have something to pin the loss on, but he knows he didn’t convert his chances Sunday at TPC Summerlin. Watney’s back-nine 34 was his highest total on that side this week. He took a disappointing par for the second day in a row on the drivable par-4 15th but was in position to again tie for the lead on the par-3 17th. While looking at a putt inside 20 feet on, Watney saw leader Kevin Na hole a 40-footer, his third consecutive birdie, to pull two shots ahead. Watney was unable to answer, missing his birdie try, before both players parred the 18th. Na was the Justin Timberlake Shriners Hospitals for Children Open champion and Watney was two shots shy of a third 2011 victory. “Well, I didn't make as many putts as I would have liked, and Kevin made a bunch of them,” Watney said. “So all the credit goes to him … It’s definitely disappointing, but you know, I just take what I can learn and go on to the next one.” There were some lessons to be learned for the four-time TOUR winner. Watney was playing in his seventh event in nine weeks and Sunday’s runner-up finish was just his second top 10 in that stretch. That’s a far cry from the numbers Watney had in January through July: 15 starts, eight top 10s and two victories. “I learned how serious I was taking it, how badly I wanted to play well the last couple months, an that didn’t always translate into good golf,” Watney said. “So this week I came in here with no expectations. I just took it very easy and played pretty nice. So I’m going to (try and) take it a little more easy and hopefully this will carry over into China.” Nick Watney has the World Golf Championships-HSBC Champions (Nov. 3-6) in China and the Presidents Cup in Australia (Nov. 17-20) on his upcoming schedule That Presidents Cup appearance, the first for the world’s 11th-ranked golfer, is something Watney is looking forward to. He talked about “tightening up” his wedge game to give himself a chance at being a bigger contributor at Royal Melbourne. “I think it's definitely cliche, but I just have to take care of myself and win the matches that I can,” Watney said. “We're definitely going over there to win, and you know, that's what we want to do. But as far as I'm concerned, just need to try and win my matches and hopefully we'll get enough points.”
