By Chris Dunham, PGATOUR.COM At No. 122 on the money list, Steve Flesch knows he has work to do to be fully exempt on the PGA TOUR next season. He also knows that dozens of golfers will be chasing him for his spot inside the top 125. Flesch opened with a 6-under 65 at TPC Summerlin that has him one shot off the Justin Timberlake Shriners Hospitals for Children Open lead. His round featured eight birdies against two bogeys, and was one shot shy of his best showing at TPC Summerlin since 2004. “If you don't get off to a good start here, you feel like you're just trying to play catch up the whole week,” he said. “My mindset is I've got nothing to lose the last few weeks, so I'm going to play all four (Fall Series events), see what happens. I'm going to play aggressively. That's how you have to play in Vegas.” Flesch’s aggressive play paid off Thursday. He birdied five of his first 10 holes at TPC Summerlin and hit 83 percent of his greens in regulation despite missing five fairways. Flesch had been hitting 59 percent of his greens up to this point in the season. “If you do hit it in the rough you have to think about what you're doing,” Flesch said. “And a couple of guys in our group did not have pitch-out lies but they had lies where they could not get to the green from about 160 yards. It's sketchy in spots but you still have to drive it in the fairway.” The four-time PGA TOUR winner is in search of his first victory since the 2007 Turning Stone Resort Championship -- the first event in the history of the Fall Series. His best finish since that victory was a tie for third at this year’s Reno-Tahoe Open.
