Rory McIlroy and Scottie Scheffler are among the stars set for brutal conditions at the St. Jude Championship this weekend.

Temperatures are set to soar to around 45 degrees Celsius in Memphis for the tournament that runs until Sunday 16 August.

Scheffler is one of a number of star golfers in action in Memphis this weekend

Justin Rose is hoping to successfully defend his St. Jude crown having claimed victory at TPC Southwind last year.

While golfers are used to playing in the summer months, they’ll need to take extra precautions as they look to battle the heat in Tennessee.

And in the lead up to the tournament, Scheffler outlined the importance of hydration and to not get ‘waterlogged’ on the course.

“You can only drink so much water out on the course without getting waterlogged,” the American said.

“That’s something that we actually experience at home depending on, if I take a break to eat lunch and go back out and chug a bunch of water, you can get waterlogged.

“It feels like it sits in your belly sometimes.”

Scheffler added that it’s more about just taking on water when the temperatures are high.

“A lot of the hydration is something you have to focus on beforehand, and it’s not necessarily water, it’s a lot of electrolytes and stuff like that,” he continued.

“The heat is something you really have to prepare for ahead of time.”

Scheffler also revealed that his wife makes protein balls to have on the course, while caddie Ted Scott is always carrying snacks in his bag.

“Some days I eat them; some days I don’t. It depends on if I get hungry or not. I’m not super structured in that part,” he said.

“I almost try to view the Playoffs as one big, long tournament, like a 12-round event. You’ve got to pace yourself. It’s three long weeks.

“We’re going from here to St. Louis to Atlanta. Every week is going to feel a bit like this. It’s going to be hot and sweaty. So, you want to be able to conserve energy as well.”

‘Electrolytes, water, and keep going’

McIlroy, who resides in Florida, is used to the hot and humid weather, but it pales in comparison to other places that the 2026 Masters winner has played.

“I’ve played a lot in like Southeast Asia, like at the start of my career,” he said.

“So, Singapore, Malaysia. There’s been times where it’s just been absolutely miserable.

“Like this is hot here, but it’s not like the humidity that you get in some of those places is just next level. This is bearable compared to some places.”

“I think the weekend is going to be a little tougher than these last few days, but it’s fine. We’re playing in two-balls. We’re going to be out there for probably like four hours.

“It’s not like you’re in that heat for five-and-a-half, six hours with a full field. So, I guess that’s a positive.”
