The Zurich Classic of New Orleans had an interesting occurrence on Thursday as a three-legged alligator decided to go for a stroll through the golf course during play.   You can see from the video that the large creature got pretty close to a rules official who was much braver than I would ever be.  The rain soaked TPC Louisiana fairways must have seemed very comfortable for the alligator as he took his time enjoying a good walk spoiled.  Ricky Barnes managed to play around the reptile and finish with a one-stroke lead heading into Friday.
