In this year of the young gun, there’s still something to be said for experience. Making his 13th start in the Justin Timberlake Shriners Hospitals for Childern Open, 41-year-old Tim Herron is 11 under through two rounds, just one shot off the pace. He’s one of just two 40-somethings among the 11 players at 10 under or better. Herron attributes his early success at TPC Summerlin to his history at the course. “I know it's a shootout on the weekend, so I'm just hoping to keep rolling the putts,” he said. “Today I made a lot of 15, 20-footers. I know the greens pretty well, so I need to stay aggressive with the putting.” Herron had a streak of three consecutive top-30 finishes at Summerlin snapped last year when he missed the cut after a pair of 71s. After a 65-66 start, his best first two rounds here since 2003, the four-time PGA TOUR winner is positioned to move up from No. 105 on the money list and secure his TOUR card for 2012.
