Phil Mickelson is in full agreement with one of his fellow professional golfers: He is a total “golf sicko.”

Michael Kim, currently ranked No. 156 in the world, took to Twitter Saturday as Mickelson slogged through the rain during the third round of the 2023 PGA Championship at Oak Hill, and shared what it was like playing with the six-time major winner during the 2021 Farmers Insurance Open at Torrey Pines.

“After all these years he was still GRINDING out pars even when we were in 50th place,” wrote Kim, who finished seventh at the Wells Fargo Championship two weeks ago. “He was so into the round. Nobody was there, still gave fist pumps and his trademark tip of the cap when the three volunteers clapped for a good shot.

“He loves to play golf. During off weeks, he plays constantly and will play you for whatever on the course.

“Had his coach on the bag and was constantly talking about the things he was feeling and what was working and not working.

“Basically guy is a golf sicko.”

Mickelson, 52, responded to Kim on Twitter.

“True True True True AND TRUE,” Mickelson wrote.

Mickelson has had a rough go of it this weekend in Rochester but managed to make the cut, his 100th made cut at a major championship.

He shot a 5-over 75 in the third round to enter Sunday’s final round at 10-over, 16 shots back of leader Brooks Koepka.

After a stunning final round at the 2023 Masters earned him a tie for second place, Mickelson believed he was “ready to go on a tear.”

In his three subsequent LIV Golf events, Mickelson finished 16th, 15th and 45th.

Mickelson also drew attention on a rainy Saturday for wearing what appeared to be sunglasses, but he explained that wasn’t the case.

“They are light enhancement glasses that are made for overcast and rainy days,” Mickelson wrote on Twitter. “They add light, helps to read greens, and protects from wind and rain drops. They’re not for everybody. In fact, not many people even know of them.”
