Jason Day was simply zapped.
All the energy and effort needed to get through his third round caught up with the Australian on the final day of the U.S. Open on Sunday.
On another warm, grinding afternoon, Day couldn't muster up the energy needed for the final round. Still feeling the effects of vertigo, Day closed with a 4-over 74. After shooting a remarkable 68 in the third round, Day was still on the verge of contention when he made it through the front nine at 1 over.
But he bogeyed two of the first four holes on the back nine and couldn't make birdie putts at the 11th and the drivable par-4 12th.
Day said he started feeling better after the 12th hole on Sunday after feeling worse as the day went on in the third round.
