ST. SIMONS ISLAND, Ga. -- Overnight leaders Webb Simpson and Zack Miller have both seen their names drop from the top of the leaderboard. Simpson remains at 7 under and doesn’t take the course at Sea Island until 12:30 p.m. while Miller is 3 over through 11, dropping to 4 under for the week. Now atop the leaderboard is 2010 q-school graduate and PGA TOUR rookie Michael Thompson. The 2010 Hooters Tour Player of the Year entered the day at 5 under and completed the back nine, his opening nine, in 2-under 33. He’s added two birdies through six holes to sit atop the leaderboard at 9 under. One off the pace is 2010 British Open Champion Louis Oosthuizen, another rookie on TOUR. Oosthuizen started on the front nine and got to 6 under for the week with a 34. Moments ago, he made a 5-foot eagle putt on the par-5 15th at Sea Island to reach 8 under, just one shot behind Thompson.
