Brooke Henderson, the winningest Canadian golfer in LPGA history with 14 victories, has shared a deeply emotional chapter in her career: the end of a decade-long partnership with her sister Brittany as her caddie. The transition, announced ahead of the 2026 season opener, stems from a joyful but bittersweet life milestone—Brittany’s pregnancy with her first child, expected in June.
Brittany Henderson (now Sepanik after marrying Zach Sepanik) joined Brooke’s bag full-time in 2015, just a year after Brooke turned professional. Together, they navigated the highs of elite competition, with Brittany on the bag for 13 of Brooke’s 14 LPGA wins, including major breakthroughs and consistent top finishes. The sisters were virtually inseparable on tour—traveling together, strategizing yardages, and sharing the unique bond of family in the high-pressure world of professional golf. “Britt and I have worked so well together for the past 10 seasons—and she is my best friend,” Brooke said in interviews leading up to the change.
The decision to step away came as Brittany prepared for motherhood. The physical demands, constant travel, and long hours of caddying made continuing full-time untenable during pregnancy and early parenthood. Brittany carried the bag one final time at the Hilton Grand Vacations Tournament of Champions at Lake Nona Golf & Country Club in Orlando, Florida—the LPGA’s season-opening event in late January 2026. The week carried extra weight: Brooke fired a strong 6-under 66 in brutally cold and windy conditions during the third round, hanging near the leaderboard while knowing it was likely her last tournament with her sister on the bag.
In post-round and pre-tournament interviews, Brooke was visibly moved when discussing the shift. The word “everything” kept surfacing as she reflected on what the change meant. “Pretty much everything,” she replied when asked about not having her sister on the bag in the coming months. “We’re together all the time, basically 24/7 when we’re out on tour.” She expressed pure happiness for Brittany and Zach, calling it an “exciting new chapter,” but admitted it would “change a lot of things.” Brooke described the decade as “so fun” and “so cool,” marked by shared successes and an unbreakable sibling connection.
Veteran caddie John Killeen, with 40 years of tour experience including stints with Cristie Kerr and Juli Inkster, stepped in to take over the bag starting after Orlando. The handover was smooth and professional, but the emotional layer was undeniable—Brooke emphasized how Brittany’s guidance and presence had been integral to her game and personal life.
Brittany has left the door open for a potential return, possibly for select late-season events like the CME Group Tour Championship or Grant Thornton Invitational in November or December, depending on family needs. For now, the focus is on this new phase: welcoming a baby while Brooke adapts to a different dynamic on the course.
The story resonates as a reminder of how life intersects with sport. What began as a family trial in 2015 evolved into one of the LPGA’s most enduring and successful player-caddie relationships. As Brooke continues chasing titles in 2026—now with fresh energy from her WTGL involvement and a new voice in her ear—the bittersweet farewell to her sister’s on-course role underscores the depth of their bond. It’s not goodbye forever, but a pause for life’s next chapter—one filled with joy, change, and the promise of future reunions on the fairways. Brooke’s raw emotion captures it perfectly: after 10 incredible years side by side, this transition is about family growing in every sense.
