Day ended the 2017 PGA Tour season strongly but dropped to ninth in the world after spending 47 weeks as world No1.
The 2015 PGA Championship winner took a break from the game in March after his mother’s cancer scare.
But the 29-year-old still managed to qualify for the Tour Championship, finishing tied 17th in the Fedex Cup after coming fourth at the BMW.
He hopes to start the new season well and is playing at the CJ Cup where he started with a four under to sit tied 12th after the first round.
And Day says he knows what improvements he needs to get back to the top.

“Hopefully the distractions that I’ve had on the golf course and off the golf course have gone away and I can focus on climbing back to No 1,” Day said.
“It seems everyone just recently has gone through a big stint where they’ve played well for a year or year and a half, go to world No 1, and then the next person comes along and does the exact same thing.
“For me personally I need to drive it better, I need to have my short game better so wedges and chipping, and my putting.
“If I can get those three things back in order where they should be, I feel like I can get back to winning a lot of golf tournaments.”
