Jason Day will no longer lean on the advice of Colin Swatton, the mentor and swing coach who helped him for more than 20 years.
“It’s been a long and successful road working with Col," Day told PGATour.com's Ben Everill on Wednesday. "I have just decided I want to make a change and work on my own as it pertains to my golf swing."
Day began working with Swatton at a boarding school in Australia when the future pro golfer was 12 years old. Day's coach was his father figure after his father died of cancer shortly before he began attending the school. Swatton ultimately helped Day win 12 PGA Tour events and rise to No. 1 in the world, where he remained for 51 weeks in 2015-16.
“Col has been way more than just a caddie and coach to me," Day said Wednesday. "I am forever grateful for all he has done for my golf and his continued friendship."
Day collected eight of his 12 Tour victories during his aforementioned outstanding campaign, but he has yet to win one since the 2018 Wells Fargo Championship. The 32-year-old fell out of the top 50 earlier this season for the first time in a decade, but consecutive top-10 finishes have vaulted him back up to No. 43 this week.
Swatton was Day's caddie for 10 of his Tour wins before focusing solely on coaching duties beginning in late 2017.
