Brooke Henderson is adjusting to life on the LPGA tour without her sister Brittany, who is pregnant. Henderson is now working with veteran caddie John Killeen as she navigates this significant change.
Mentioned in this story
Brooke Henderson has been on the LPGA for more than a decade now, but 2026 has surely felt, at times, like a rookie year.
For her entire professional career, Henderson traveled the world with big sister Brittany by her side. Now, with Brittany pregnant with her first child, Henderson begins her fifth tournament of the season with veteran caddie John Killeen at this week's JM Eagle LA Championship.
"It's been weird for sure," said 28-year-old Henderson of life on the road without Brittany. "You know, she's my best friend, and for 11 years we traveled together and were together basically 24/7 except for off weeks.
"It's been a big change, but I still talk to her all the time, so that part hasn't changed too much. But, yeah, just adjusting to the new life out on tour, dealing with what most players have dealt with their entire career, so that's kind of interesting to learn more about."
