Jason Day will have a new caddie on his bag for this week's BMW Championship, according to Golf Channel's George Savaricas.
While Swatton will remain Day's swing coach, his departure from his star pupil's bag might be the most surprising in a year that hadn't already seen Phil Mickelson and Rory McIlroy split with their longtime sidekicks.
Day and Swatton first met at the Kooralbyn International School in Queensland, Australia, where Day's mother had sent him after the golfer's father had died.
Day has taken his coach Colin Swatton out of the looper role while maintaining their long-standing player-coach relationship.
"Everything is great when you win, but when you're playing poorly, that's when a true test of a relationship actually happens between a player and a caddie", Day said.
It brings to an end a lengthy partnership which started before Day turned professional in July 2006. Now he'll be the caddie for Day in the BMW Championship, the third FedEx Cup playoff event, in which the top 30 advance to the FedEx Cup finale and a shot at the $10 million bonus prize.
"He was obviously a little bit shocked and disappointed", Day said.
To preserve the most important relationship in his golfing life, Jason Day had to cut loose the man who made that life possible. Day said he would prefer to work with Swatton in the days and weeks leading up to tournaments, so he's not trying to fix anything at an event. Once again, he's my coach and always will be. "I'm planning on trying to keep him around". He said, 'You can yell at me if you want, ' - that's how good of a guy he is. "He's a father figure for me ever since I was a kid, and I wanted to make sure that it's still there". "It's hard because we've been a team for so long. Obviously, when you let go of someone sometimes it's hard, but there's been a lot going this year".
The year began with Day trying to get his mother to doctors in OH, where he lives, to be treated for lung cancer.
