Rickie Fowler overcame some bad shots for a share of the lead Thursday in the Waste Management Phoenix Open. Phil Mickelson compounded his mistakes and fell back.

After an hour-long frost delay at chilly TPC Scottsdale, Fowler played the first six holes in 5 under. A group behind, Mickelson took the lead at 5 under with a birdie on his eighth hole.

While Fowler finished with a 6-under 65 to tie Shane Lowry and Hideki Matsuyama for the lead in the suspended first round, Mickelson had a 69 after dropping four strokes in a two-hole stretch.

Mickelson bogeyed the par-3 fourth after hitting short and right and failing to reach the green with his second, and unraveled with a triple bogey on the par-4 fifth. He drove out of bounds to the right, hit his second tee shot into the right bunker and three-putted from 50 feet.

Mickelson's best shot was on the par-5 13th -- his fourth hole of the day -- when he hit a 252-yard hybrid approach to 2½ feet to set up an eagle.

Fowler opened with a birdie on the par-4 10th as the temperature crawled into the 40s, holing a 16-foot putt. He made a 35-footer on the 12th, two-putted for birdie on the 13th and made a 28-foot eagle putt on the par-5 15th after hitting a 258-yard shot over the water.

The top-ranked player in the field at No. 4, Fowler bogeyed the par-3 16th after drawing an awkward lie in the right bunker. He birdied the short par-4 17th, and bogeyed the par-4 18th after driving left into the water. On his back nine, he got up-and-down for birdie from a greenside bunker on the par-5 third and closed with a 12-foot birdie putt on the par-4 ninth.

Bubba Watson opened with a 69, finishing in fading light a day after saying he doesn't like the renovated course and is only playing the tournament out of loyalty to his sponsors. The two-time Masters champion tied for second the last two seasons.
