Jason Day failed to win a tournament last season while dropping from No.1 to No. 9 in the world rankings.
He did finish last season with six straight top 25s, including three top 10s, but Day rarely contended. He also fired longtime caddie and father figure Colin Swatton.
Day originally reached world No. 1 in March 2016, but he relinquished it to Dustin Johnson in February. Johnson has held the position since.
“I think I was a little burnt out from 2015 and 2016,” Day told reporters this week at the CJ Cup in South Korea. “I did not know how to handle being No. 1 at that time. The next time I get there, I will handle it a little bit differently.”
Day shot an opening-round 4-under 68 at Nine Bridges and trailed Justin Thomas by five shots after Round 1.
Held without a win since the 2016 Players Championship, Day is ready to get back on track this season.
“Now, I’m able to focus back on golf,” Day said. “Hopefully the distractions that I’ve had on the golf course and off the golf course can go away, and I can start focusing on getting back to climbing back to No. 1.”
