PALM BEACH GARDENS, Fla. — Brooke Henderson will have a new face on her bag for the bulk of the 2026 LPGA Tour season as her sister and longtime caddie, Brittany, prepares for a different kind of delivery.
The Henderson family confirmed that Brittany is pregnant and expecting her first child with husband Zach Sepanik in June. As a result, Canada’s winningest professional golfer will turn to veteran looper John Killeen to handle caddie duties for most of the upcoming campaign.
“Britt and I have worked so well together for the past 10 seasons — and she is my best friend,” Brooke Henderson said in an interview with Sportsnet’s Adam Stanley. “We travel together all the time, so this is going to be a big change, but I’m looking forward to the challenge.”
The Henderson sisters have formed one of the most formidable and recognizable partnerships in professional golf. Since Brittany took over full-time caddie duties in 2015, she has been on the bag for 12 of Brooke’s 13 LPGA Tour titles, including two major championships.
The transition will not be immediate. Brittany is scheduled to caddie for the season-opening Hilton Grand Vacations Tournament of Champions in Orlando, which begins Jan. 29. Brooke enters that event as a past champion, having won the tournament with Brittany in 2023.
Following the opener, Killeen will take over the bag as the tour moves to Asia. Killeen brings more than 40 years of experience to the role, having previously worked for Hall of Fame members Juli Inkster and Meg Mallon, as well as major winner Cristie Kerr.
While Killeen handles the yardages, Brittany’s absence will also be felt on the practice range. In addition to her role as caddie, she has long served as Brooke’s de facto swing coach while on the road, acting as the eyes and ears for their father and primary coach, Dave Henderson.
Brittany, a former professional golfer herself and a member of the Coastal Carolina University Athletics Hall of Fame, hasn’t completely ruled out a cameo later in the year. She suggested a return for the season-ending CME Group Tour Championship in November remains a “hopeful possibility,” provided the timing and logistics of new motherhood allow.
For the 28-year-old Brooke, the 2026 season represents a major shift in her professional environment, but the Smiths Falls, Ont., native said she is focused on the personal milestone for her sister.
“I’m super excited,” Brooke said. “It’s amazing. I’m really happy for Brittany and Zach and I’m excited to be an aunt as well.”
The 2026 LPGA season features a record-breaking schedule, with Henderson expected to remain a central figure in the hunt for her 14th career victory and a climb back up the Rolex Women’s World Golf Rankings.
