Shane Lowry Parts Ways with Longtime Caddie Ahead of Travelers Championship

Following a missed cut at the 2026 U.S. Open at Shinnecock Hills, Shane Lowry confirmed on June 24 that he is no longer working with caddie Darren Reynolds. The decision was reported by Golfweek and reiterated by Lowry during the Travelers Championship in Connecticut. For the tournament, Lowry enlisted Dermot Byrne, who carried his bag during the first decade of Lowry’s professional career and was on hand for victories at the 2009 Irish Open (as an amateur) and the 2012 Portugal Masters. Lowry described Byrne’s role as a short-notice arrangement while he determines a long-term caddie plan.

Lowry’s form has slipped since a late-round collapse at the Cognizant Classic in March 2026, where two balls entered water and he lost a lead. Subsequent missed cuts at the Arnold Palmer Invitational and the Players Championship left him without a top-20 finish in nine starts. He has missed four cuts in his last eleven outings, a contrast to his prior streak of missing no more than three cuts per season (2020-21 onward). After the U.S. Open, Lowry said the game “is just not agreeing with me at the moment” and that he “didn’t have any fun this week.”

Lowry turned professional in 2009 and has three PGA Tour victories, including the 2019 Open Championship (caddied by Bo Martin). He finished tied for second at the 2016 U.S. Open, tied for third at the 2022 Masters, and tied for fourth at the 2021 PGA Championship. From 2023 until the recent split, Darren Reynolds served as his full-time caddie, a partnership that produced a win at the 2024 Zurich Classic of New Orleans and consecutive top-15 finishes at the Tour Championship. Prior to Reynolds, Dermot Byrne was Lowry’s primary caddie for ten years.

Lowry’s father, former Offaly Gaelic footballer Brendan Lowry, underwent a left-hip replacement twelve years ago and a right-knee replacement three years ago after a career marked by severe joint pain. Lowry has spoken about the difficulty of watching his father’s suffering and his role as a caregiver. In June 2026 he announced a brand-ambassador partnership with medical-equipment company Stryker, citing a desire to help others facing similar mobility challenges.
