Rickie Fowler will take a one-shot lead into the final round of the Waste Management Phoenix Open after a big finish on Saturday in Arizona.

The American entered round three in a tie for the lead but was not at his best in the early stages as he turned in level par before birdieing the 13th.

A birdie-birdie-birdie finish saw him card 67, then propelled him to the top of the leaderboard on 14 under.

Fowler enters the final day ahead of countrymen Bryson DeChambeau and former Arizona State alumni Chez Reavie and Spaniard Jon Rahm, who posted a 65 to tie for second.

Dechambeau signed for a round of 68 to join them in second, one shot ahead of five-time major champion – and another former Arizona State player – Phil Mickelson, as well as Daniel Berger and Xander Schauffele.

Fowler told CBS Sports: “It was a grind. Just a little off in certain areas and just kind of tried to piece things together.”

Rahm ended his round well with four birdies in his last six holes, while Reavie had a birdie-birdie finish.

Scotsman Martin Laird birdied three of his last four holes to sign for a 68 and sit four shots off the lead.
