Jason Day

PGA Champion Jason Day talked on Wednesday for the first time since his first major win on Sunday and said he's been getting plenty of rest and quality family time in over the last couple of days.

Reality of Day's PGA Championship victory still sinking in

In the 48 hours since Australia's Jason Day captured his first major championship title -- the PGA Championship at Whistling Straits -- he has spent quality time with family and catching up on some much needed rest.

"The last 48 hours for me personally has been more so just trying to catch up on the time with the family, catch up on rest and just spending good quality time with the family, because I really didn't get to see them last week," said Day, who defeated Jordan Spieth by three shots at a major championship record 20-under-par, 268 total. "And being able to try and rest and recover was huge, because it was a long two weeks for me, especially last week was very, very long for me. It was mentally and physically draining.

"To be able to get some much needed rest was great," added the 27-year-old and first Australian to win the PGA Championship since Steve Elkington in 1995. "But I would be happy to put myself through that exact same stress, that long of a week, just to be able to hold the Wanamaker Trophy again."

Following a heartbreaking defeat at the Open Championship where he tied for fourth at St. Andrews, one shot out of a playoff, Day said his bounce-back win the next week at the RBC Canadian Open helped his confidence immensely going into the season's final major.

"I felt like my first major championship victory was going to be at The Open Championship at St. Andrews," he said. "I just great that week. I felt good about my game; and then to pull up so short with the frustrating putt on the last hole. But then again, turn around that week on a short week and fly straight back to Canada and play in the RBC Canadian Open and win that, especially with how I did it with three birdies in the last three holes to win by one, definitely helped the confidence; knowing that what I was doing at the time was good enough to win, and what I was doing mentally and physically to prepare for a tournament was exactly spot on what I needed to do; the confidence is high."

Over the last three seasons, few have been better than Day in the majors. Since 2013, Day has been among the top-10 in seven of the 12 majors played.

Day's belief was that it was only a matter of time before he hoisted some major hardware of his own and said he chose to view those tough defeats as invaluable learning experiences. The losses only inspired him to give more of himself toward tackling that ultimate goal.

"Yeah, I definitely felt like I was an underachiever," Day said. "Especially since I feel like I have all the talent in the world to win on many golf courses and major championships. I honestly thought I was going to win a major championship quicker than what I did, but it clearly took a little bit longer than expected.

"You know, I was thinking about it, and I'm glad all those things happened to me," he added. "I'm glad all those frustrations and experiences of failures that I've had in the past happened because I used it as a learning tool to really push myself and be able to reach this accomplishment of winning the PGA Championship last week. "

Regarding his schedule for the remainder of the year, Day pointed to turning his focus to the PGA Tour's FedExCup Playoffs -- which begin next week at the Barclays in New Jersey -- the Presidents Cup in Korea in October, and spending plenty of time with family while continuing to work vigorously on his body and game. Day and wife, Ellie, are expecting their second child in mid-November.

"It's been a great year but I really need to take time off to really kind of debrief and really understand what was going on this year, what I've done great, what I need to improve, and really try and get after it with my body, really try and change and get it to where I really think I need to get my body to the point where it's not going to break down again," he said. "I'll probably take off some time and then maybe kind of reevaluate things once I get into late November. I'm going to go defend Shark Shootout. I'm thinking about going to play Tiger's events. But right now I'm just focusing on the FedExCup Playoffs."
