SCOTTSDALE, Ariz. -- Brandt Snedeker continues to apply pressure but he may be running out of holes at the Waste Management Phoenix Open.

Snedeker made a 5-footer for birdie at the par-3 16th, the tournament's wildly entertainly signature hole, to pull within three strokes of Mickelson. The leader, who is 27 under, narrowly missed a 15-footer for his own birdie there.

The group has two holes remaining. The 17th is a driveable par 4 that is playing to 317 yards on Sunday with the pin on the extreme left of the green. The 18th is a 449-yard par 4 with ample water in front of the tee and continuing down the left side of the fairway.

Mickelson is 3 under at the 17th while Snedeker eagled it in the first round and made a birdie there on Saturday.

Mickelson double bogeyed the 18th on Friday but made birdie there on Thursday and Saturday. Snedeker has played it in 1 under.
