Things went terribly wrong for West Chester's Sean O'Hair yesterday on the 17th hole at TPC Sawgrass:

His 9-iron tee shot flew a yard over the back of the green and splashed into the water.

Then he put another ball in the water, this one skipping toward the back of the green and bouncing over the boards.

When the hole was over, O'Hair had a quadruple-bogey 7.

O'Hair approached the hole trailing Phil Mickelson by 2 shots. He finished his round in 11th place, 6 shots behind.
