Saturday is moving day on the PGA Tour, and yesterday at the Shell Houston Open it was surely moving day for the top spots on the leader board.  At one point there was 5 players tied for first at -12 under, and another 3 or 4 hovering around -11 under.  The log jam that took place in the day was knocked loose by Hunter Mahan and Louis Oosthuizen.  Hunter Mahan had the low round of the day of 65 to secure him a top spot on the leader board.  That is until Louis Oosthuizen decided he was going to bag himself 5 birdies on the back nine to take the lead from Mahan and finish at the very top of the leader board on Saturday night with a third round 66 to propel him to -17 under par.

Carl Pettersson is still hanging around the last few groups (2nd to last on Sunday) with a three round total of -14 under par to put him three shots back of the 2010 Open Champion Oosthuizen.  Brian Davis also had a solid Saturday to finish at -14 under par.  Other notables:  James Driscoll, Ryan Palmer, Keegan Bradley, and Phil Mickelson are all within 5 or 6 shots of the leader.

Louis Oosthuizen has not won since his major break through at the 2010 Open Championship, but he never once faltered on Sunday at St. Andrews.  I wish I could say that Louis Louis might fall back on Sunday and allow for some fireworks from the other players, but my guess is that someone is going to have to go real low to beat Oosthuizen on Sunday.
