What it means: Perez, 40, underwent surgery to repair a torn labrum in his left shoulder in March and sat out the rest of the 2015-16 season. While he was rehabbing he made a major equipment change - to a TaylorMade driver, Titleist ball and PXG irons and claimed that he picked up 30 yards off the tee. He also adopted a more aggressive attitude on the course. The combination worked, as he is a combined 44 under par for three events this season. At Mayakoba, he had talked all week about the scoring opportunities on holes 1-7, and on Sunday, he played them in 4 under. He added another birdie on the front, then cruised home on the back with eight pars and a bogey for a 67. His second career win came almost eight years after his first.
Round of the day: Brian Gay shot a bogey-free, 7-under 64 that featured five birdies on the front and two on the back. He vaulted 35 spots up the leaderboard, to a tie for 28th place.
Best of the rest: Kevin Streelman's 65 boosted him 10 spots to a tie for fourth. He could have improved that finish by one place had he not bogeyed the final hole.
Biggest disappointment: Gary Woodland started the final round with a one-shot lead over Perez, but he couldn't get anything going until it was too late. Two closing birdies gave him a 1-under 70 and a second-place finish. It was the fifth time in six occasions that Woodland has failed to convert a 54-hole lead or co-lead.
Shot of the day: The 10th hole, a 200-yard par-3, has vexed many players, but Russell Knox had no problem with it on Sunday, hitting a 7-iron to 6 inches for a tap-in birdie.
Quote of the day: ''I guess I'm just one of those late-maturers. I know I was sort of a punk and all that early on, but I think I learned a lot about myself in the last nine, 10 months and it just paid off this week. I couldn't be more excited about what's going on.'' - Perez
