Casey was at 15 under, tied with Scott Stallings, who closed with a 66. Along with an outside chance at forcing a playoff, finishing alone in second instead of a tie is a difference of $152,000, along with world ranking points and FedEx Cup points. Casey and FedEx executive

Don Colleran had a oneshot lead in the pro-am.

Jason Day closed with a 68 and was tied for fourth at 13-under 175 with Si Woo

Kim (68).

Phil Mickelson put himself on the brink of a fifth victory in the AT&T Pebble Beach Pro-Am by turning a three-stroke deficit into a three-shot lead when a wild day of weather kept him from finishing.

Mickelson was bogeyfree with six birdies, and he made his big run starting with a 9-iron to within a foot behind the cup on the par-4 ninth. That was start of a five-hole stretch when Mickelson made three birdies and Paul Casey had two bogeys.

The final round started an hour late because of rain, and then it was delayed two more hours when sunshine gave way to a hail storm in a matter of minutes, covering the putting greens in a sheet of white.

Mickelson was at 18under par through 16 holes. Casey had a 3-foot par putt
