Tiger Woods' classy gesture for coachless Jason Day

With no plans to find a new coach, Jason Day has revealed he's using Tiger Woods as a mentor in his bid to once again scale the heights in world golf.

Like Day, Woods has battled chronic back injuries throughout his career, prompting Australia's former world No.1 to turn to the 15-times major winner for advice on how to best modify his swing to protect his battered body.

"I have been actually talking to Tiger about his swing and what he's been doing because I think he has the best swing out there, especially the iron swing. It's amazing," Day said on Wednesday.

"He's gone through some back issues and he's doing a lot of good things to try and alleviate his pain and I just feel like I ask questions and he's willing to answer them and I'm trying to make changes now with my swing."

The resurgent Day, who heads into this week's second FedExCup playoff event in Chicago boasting four top-10 starts from his past five tournaments, has made a conscious effort to slow down his swing this year.

"I can get the club speed up to 120 (miles per hour) and the ball speed up to 180 easy, if I want to," he said.

"But I don't try to do that anymore because a) I don't think it's great on my back and b) I'm putting a premium on hitting the fairways."

Despite a series of setbacks, the 32-year-old is confident his career has no used-by date because of his back problems, saying he spends two hours daily keeping his body in order through massages and exercising.

"I'm not 21 anymore," he said.

"So if I want to add any more years to my career, I have to put in the work in regards to doing what I'm doing right now," Day said.

"I currently feel tremendous. I feel great with my body. Touch wood, everything keeps moving in that direction."

The 2015 US PGA champion remains driven to return to world No.1 and not finish his career as a one-major wonder.

"I know that I'm currently 35th in the world right now and I know there's a lot of young guys out there, but the good thing about golf is that it really doesn't matter how far you hit it," Day said.

"It's not like any other sport in regards to like football or cricket or anything like that where a guy comes in and he's just that much more athletic and you just can't do anything about it."

Day parted ways with lifelong coach Col Swatton in July.

I'm moving more towards the ownership of my own golf swing with some help from like Tiger and some other coaches that I haven't talked to yet, but I think are very respectable," he said.
