Players Championship leader Webb Simpson arrived at the par-3 17th Friday 11 under on his round and in need of a birdie-birdie finish to shoot 59.
Coming off a run of six straight birdies from Nos. 11-16, Simpson took aim at the island green but instead found the bulkhead - and then the water.

Simpson went on to make double bogey at 17 and a par at 18 to shoot 63 and stake himself to a five-shot lead at 15 under par.
