We now have a five-way tie for the lead for at least the next few minutes.
Jimmy Walker was cruising at 9 under until he reached the par-4 11th, which is guarded by water entirely down its right side. That part got Walker, who rinsed his tee shot and had to settle for double bogey. Only three players: Walker, Chad Campbell and Jarrod Lyle.
