A big reason? He brings his own mattress to events.
Tired of dealing with hotel beds that are either too firm or too soft for his liking, Oosthuizen gets his own mattress loaded onto an equipment truck and dropped off at his hotel each week on Tour.
“Some weeks I use it, some weeks I don’t,” he said after losing, 5 and 4, to Jason Day in the WGC-Dell Match Play final. “If there’s a mattress at the hotel that I’m not comfortable with, I’ll use my mattress.”
It’s quite a process, apparently, with Oosthuizen’s manager, Louis Martin of International Sports Management, hauling the mattress off the truck and storing it in a hotel closet in case Oosthuizen requests it.
“It’s a piece of cake,” Martin said with a laugh, later adding: “But if it makes him play better, I'm happy to do it.”
Oosthuizen’s back has caused him fits for years, and it’s one of the main reasons why he has failed to build on his major breakthrough at the 2010 Open.
“This week was a massive week for me to be able to do 72 holes in two days,” he said. “That means I’m definitely going in the right direction with the training I’m doing.”
