golfer Alejandro Tosti reportedly staged an unusual protest at the Houston Open after he was left unimpressed by a rival. He and eventual winner Min Woo Lee were playing together at Memorial Park Golf Club alongside Ryan Fox when frustrations seemingly got the better of Tosti.

Commentator Jim Mackay, a former Phil Mickelson caddy, claimed that Tosti complained to the officials and then deliberately walked 100 yards behind his two playing partners on the 12th hole.

It was described as an intentional attempt to slow play down, with Tosti appearing to make the point that Woo Lee had been doing just that with his pace throughout the day.

Woo Lee, who ended up winning the title as he held off , Gary Woodland and Rory McIlroy, is widely known as a careful player who takes his time around the course.

But his tactics appeared to prove fruitful in Houston as he sealed a dramatic finish. The 26-year-old led by three shots when he put his tee effort into the water on the 16th, ultimately finishing with a bogey.

Woodland took the course record of 62 by finishing with an eagle and two birdies in his final four holes, but from the previous day and finished one shot behind.

Woo Lee appeared to cause frustration with Tosti, however, especially on the par-five eighth hole. His tee shot was hit into the bush and after lengthy conversations with caddie Bo Martin, he took a drop ball.

The Australian then hit up the fairway from below the branches, taking his approach to within 10 feet and somehow saving par.

But the group had taken over 30 minutes to complete the hole as a result of Woo Lee's delays, which prompted Tosti to complain to the officials and then stage his own unofficial protest by walking behind Woo Lee and Fox.

"I don't know what's going on, but Tosti is playing at his own pace," Mackay said on commentary. "At times, it's normal. At times, it's glacially slow. But he's decided on this particular hole to really take his time, and he's holding up play in this last group."

Mackay also claimed that Tosti had clashed with Fox earlier in the round during a drop situation on the first hole.

But Woo Lee was able to put any animosity aside to take his first PGA Tour win. "It's hard, really hard," said Lee after his victory. "Scottie (Scheffler) is a wonderful golfer and he keeps you on your toes.

"This is my first time being in front and trying to hold a lead. I'm glad I got it done, but man, I'm just very exhausted. It was a lot of mental grind. I'm so proud of the way I handled myself."
