TPC Sawgrass is best known for the 17th hole (we've already gone over how famous that par-3 is earlier this week), but the hardest hole on the golf course might be the one that follows the island green.

The 18th at the Players Championship is where rounds come to die, a treacherous tee shot that calls for accuracy, length and above all else, guts.

On Thursday at a wind-free Sawgrass, the scores were as red as one can remember, and that helped make the final par-4 a bit easier. Jason Dufner took full advantage of that, hitting his tee shot a bit too close to the water for comfort, but it gave him a great angle into the tucked pin on the final green and he took dead aim.

The result? Just the third eagle in the history of the Players on the 18th, and a round of 1-under 71. Look how excited Dufner got after it went in!
