Collin Morikawa is a household name in the world of professional golf. At just 28 years old, he has already established himself as one of the top players on the PGA Tour. However, his 2025 season has been eventful, to say the least, with multiple caddie changes in just a few months.
The latest caddie to join Morikawa’s team is John Sullivan, who will be on his bag for the FedEx St. Jude Championship. This is not the first time Morikawa has switched caddies this year. In fact, Sullivan is his fifth caddie of the year. This has left many fans and experts wondering what is going on with the young star and his caddie situation.
It all started with Morikawa’s surprising split with his long-time caddie J.J. Jakovac, who had been by his side for six years. Jakovac had played an integral role in Morikawa’s success, including his win at the 2020 PGA Championship. Their partnership had seemed unbreakable, but things took a turn when Morikawa decided it was time for a change.
Caddie changes are not uncommon on the PGA Tour. However, having five different caddies in one season is quite unusual, especially for a player of Morikawa’s caliber. But the young golfer is not the only one going through a carousel of caddies this year. Let’s take a look at all the caddies Morikawa has worked with in 2025, ranked from least to most impactful.
5. Billy Williams
Billy Williams was the first caddie to join Morikawa’s team after his split with Jakovac. Williams had previously worked with other top players on the Tour, making him a promising addition to Morikawa’s team. However, their partnership lasted only for a few tournaments before Williams was replaced.
4. Kevin Shaw
Kevin Shaw was next in line to caddie for Morikawa, but his stint was even shorter than Williams’. The two worked together for only one tournament before parting ways. Shaw had previously caddied for Morikawa’s fellow competitor, Jordan Spieth, and was expected to bring valuable experience to the table.
3. Scott Taylor
Scott Taylor was Morikawa’s caddie for a brief period, but their partnership seemed to be going in the right direction. They worked together for five tournaments, including the Masters, where Morikawa finished in the top 10. However, it wasn’t enough for Taylor to secure a permanent spot on Morikawa’s bag.
2. Tony Navarro
Tony Navarro, a well-known caddie on the Tour, was the fourth caddie to join Morikawa’s team. Navarro had previously caddied for players like Greg Norman and Adam Scott, making him a highly sought-after caddie. He and Morikawa worked together for seven tournaments, including the U.S. Open, where Morikawa finished in the top 5.
1. John Sullivan
John Sullivan is the latest addition to Morikawa’s team, and only time will tell if he will be a long-term caddie for the young star. Sullivan has previously caddied for other top players like Bubba Watson and Justin Thomas, making him a valuable asset for Morikawa. Fans and experts are hopeful that this partnership will be a successful one, and that Morikawa can regain his winning form with Sullivan by his side.
In conclusion, Morikawa’s caddie changes have caused quite a stir in the golfing world. While some may see it as a sign of instability, others believe it is a necessary step for Morikawa to reach new heights in his career. After all, a caddie plays a crucial role in a golfer’s success, and finding the right fit is essential.
Morikawa has already achieved so much in his career, and it’s clear that he has high expectations for himself. With the help of his new caddie, he is determined to continue his success and add more trophies to his already impressive collection. As fans, we can only support and cheer on Morikawa as he navigates through this caddie carousel and continues to make his mark on the world of golf.
