The only thing predictable about Phil Mickelson is his unpredictability. That was clear again at the Desert Classic, a tournament he should have won Sunday.

Adam Long had quite a Sunday on the greens at the Stadium Course at PGA West. In winning the Desert Classic for his first victory on the PGA Tour, Long made seven birdies in a final-round 65, including birdie putts of 16, 15, 20 and, after a magnificent iron shot on the 72nd hole, 14 feet. Long uses a Scotty Cameron by Titleist X5R mallet putter—a design with “wings” to help boost moment of inertia to provide better performance on mis-hits.

Rickie Fowler has won four times on the PGA Tour and amassed more than $34 million in career earnings. Now in his 10th full season on the PGA Tour, Fowler is making a monumental shift in his equipment, changing to TaylorMade's TP5x ball (the number 15, in homage to his motocross days) in a multiyear agreement that also will have him wearing the company's Tour Preferred Glove. Fowler spoke with Golf Digest's equipment editor E. Michael Johnson on the process of making the switch, the new ball and how playing with Dustin Johnson in the Ryder Cup played a role in the decision.

Alvaro Ortiz of Mexico made birdie on the par-5 18th on Saturday for a 2-under 70, giving him a one-shot lead and a third opportunity to capture the Latin American Amateur Championship. Ortiz lost in a three-man playoff in 2017 and was runner-up last year to Joaquin Niemann.

It wasn't golf as much as a test of survival. A field in which 80 percent of the players are at scratch or a plus-handicap didn't break 80 as a group on Sunday in the second round of the First Coast Amateur. Sustained winds of more than 25 mph, gusts of more than 40 mph and temperatures that stayed in the low-50s chilled hands, frayed nerves and made pars a precious commodity. When it was mercifully over Stephen Shephard, a senior at NCAA Division III Huntingdon College (Ala.) and Logan Sowell, a junior at the College of Charleston, were tied for the lead at 1-over-par 145. Shephard had the day's low round with a 73 and Sowell was one of six players who tied for the next lowest score with a 75

Associated Press LA ROMANA, Dominican Republic -- Alvaro Ortiz of Mexico made birdie on the par-5 18th on Saturday for a 2-under 70, giving him a one-shot lead and a third opportunity to capture the Latin American Amateur Championship. Ortiz lost in a three-man playoff in 2017 and was runner-up last year to Joaquin Niemann.
