Shane Lowry Splits With Caddie

Shane Lowry has a new caddie at the 2026 Travelers Championship. The Irishman split with Darren Reynolds after missing the cut at last week’s U.S. Open and has reunited with Dermot Byrne, who carried his bag for the first decade of his professional career, for this week at TPC River Highlands in Cromwell, Connecticut.

The change was reported as Lowry arrived for the season’s final signature event, and he confirmed the reunion in Cromwell. Reynolds had been on the bag since 2023, so this is a notable in-season switch for a former major champion who has struggled to find his game in recent weeks.

Why did Shane Lowry split with Darren Reynolds

Lowry parted ways with Darren Reynolds after missing the cut at the 2026 U.S. Open at Shinnecock Hills. It was the latest low point in a frustrating stretch of form for the 2019 Open champion, who has been candid about how much he has been grinding without results.

Reynolds had worked for Lowry since 2023, when Lowry parted with Brian “Bo” Martin, who had caddied for him from 2018. The Reynolds partnership produced strong moments, but the recent dip in Lowry’s play set the stage for a change heading into the back half of the 2026 season.

Asked about his plans beyond this week, Lowry kept the door open. “We’ll see what the plan is going forward,” he said. “No idea really.” That suggests Byrne may be a short-term solution rather than a confirmed long-term arrangement, which is worth tracking as the schedule rolls toward the Open Championship.

Dermot Byrne returns to Shane Lowry‘s bag

Dermot Byrne is a familiar face, not a new hire. Byrne caddied for Lowry through roughly the first 10 years of his professional career before Bo Martin took over in 2018, so the two know each other’s tendencies well. Lowry reached out to Byrne on short notice once he decided to move on from Reynolds ahead of the Travelers.

Reuniting with a former longtime caddie is a comfort move. There is no learning curve on the personalities, the routines, or the read-and-react rhythm during a round, which matters when a switch happens this quickly. The open question is whether the reunion sparks the kind of bounce a player chasing form is hoping for, or whether it is simply a stopgap while Lowry sorts out his next steps.

What the caddie change means for Lowry’s Travelers betting and DFS outlook

For bettors and DFS players, a caddie change a few days before a tournament is a soft signal, not a hard edge. Lowry remains a long price in this field, and the switch does not change the underlying form questions that have followed him since his early exit from Shinnecock last week. The reunion with Byrne is a reason for cautious optimism rather than a reason to chase a number.

The course profile is the bigger factor. TPC River Highlands is one of the shortest stops on tour at a par 70 of about 6,844 yards, and it rewards accuracy off the tee, sharp wedge play, scrambling, and putting on small poa greens rather than raw distance. Lowry’s ball-striking can travel at a precision venue like this when his irons are sharp, so a clean week of approach play would matter more than the name on the bag. Until his form turns, treating him as a placement and matchup option rather than an outright play is the disciplined approach.

Who was Shane Lowry‘s caddie before Darren Reynolds

Brian “Bo” Martin caddied for Lowry from 2018 until 2023, and Dermot Byrne worked his bag for roughly the first decade of his professional career before that. Reynolds then took over in 2023, which makes this week’s move a reunion with Byrne rather than a brand-new partnership.

Will Shane Lowry play all four rounds at the 2026 Travelers Championship

Yes. The Travelers Championship is a no-cut signature event with a limited 72-player field, so every player who tees it up, including Lowry, is guaranteed all four rounds from Thursday through Sunday at TPC River Highlands. There is no 36-hole cut to survive this week.
