Rahm's return and a course redesign frame the Scottish Open — but the field's bigger story is what the 2028 revamp will do to it

The Renaissance Club, the Tom Doak-designed links on Scotland's east Lothian coast, opens the 2026 Scottish Open on Thursday with a field assembled under unusually cross-wired incentives. Jon Rahm, the 2023 Masters champion and one of the marquee names who left the PGA Tour for LIV Golf in late 2023, is teeing it up in a regular Tour event for the first time in 2026. The Spanish former world number one is not, on this evidence, returning to the PGA Tour; rather, the Scottish Open is one of the co-sanctioned Rolex Series events on the DP World Tour that retains a carve-out allowing LIV members to compete. That quirk of the calendar — a European-designated tournament sitting inside the PGA Tour's broader regular schedule — is now a small but conspicuous seam in the sport's still-unfinished split.

It matters because the Scottish Open, in the three years since the schism, has become a stress test for how the two tours coexist. Rahm's presence is the headline; the course, and what the Tour plans to do with the tournament in 2028, is the subplot that will outlast this week's leaderboard.

A reworked Renaissance Club

Renaissance Club has been lightly re-engineered for 2026. According to the BBC's tournament preview, the layout has been rejigged in ways intended to tighten the strategy on the closing holes and to give the field more options off the tee on the par-fives, without altering the fundamental Doak footprint. The work is described as a soft refresh — new tees, a reshaped green complex on one of the closing par-fours, and re-cut surrounds on a handful of approaches — rather than a redesign. Renaissance has hosted the Scottish Open since 2019, and the tournament has used the venue's exposure to the North Sea wind as its signature difficulty. Lengthening the course to offset modern ball technology has been a recurring theme at Tour venues, and the 2026 setup looks aimed at rewarding position play over sheer distance, at least in the early reports.

Rahm's incentive structure

Rahm's decision to play is, on the surface, simple: he is exempt into the Scottish Open through his DP World Tour membership, and the event sits in a window on the calendar where his LIV schedule is light. There is no readmission pathway negotiated here, and no Tour card application pending. But the appearance is a reminder that the boundaries between the two circuits remain porous at the edges. The PGA Tour's framework agreement with LIV Golf's backers, the Saudi Arabian Public Investment Fund, remains unsigned in any final form, and the operational agreement that allows cross-scheduling on a tournament-by-tournament basis is the kind of administrative scaffolding that holds the whole arrangement together. A Rahm start in a Tour-branded event is a quiet test of that scaffolding — and a chance for the Tour's marketing operation to use one of the sport's most marketable players in a sanctioned event, even if only for a week.

The counter-narrative is that none of this is new. Brooks Koepka and other LIV members have made similar one-off starts at European co-sanctioned events since 2023. What is new is the duration of the impasse: by the time the 2028 season begins, the schism will be five years old, and the Tour's own governance review will be deep into implementation. Rahm's 2026 start, in that sense, is a marker on a longer timeline rather than a turning point.

The 2028 question McIlroy is asking

The more durable story, and the one that prompted the loudest pre-tournament commentary, is what happens to the Scottish Open in 2028. The PGA Tour is preparing to introduce a two-tier format that year, splitting the schedule into a top flight and a developmental circuit. Rory McIlroy, the tournament's most prominent former champion and a longstanding critic of how the post-2023 governance reshuffle has been handled, used the pre-tournament press window to urge caution. According to the BBC, McIlroy asked the Tour to "be careful" with the Scottish Open's place in any new structure, signalling concern that a venue now considered a Rolex Series anchor on the European side could be downgraded, rotated, or quietly de-emphasised once the two-tier model lands.

McIlroy's intervention is the kind of player-led governance push that has characterised his post-2023 public role. He has consistently framed himself as a defender of the European game's standing inside a Tour restructuring that has, by necessity, been led from Ponte Vedra. The Scottish Open matters disproportionately to that argument because it is the rare event that delivers a full Tour field, a Rolex Series designation, and a links-golf test in the same week — a combination that has made it useful preparation for The Open Championship the following week, and that gives the European Tour a flagship it can point to in any commercial negotiation. Downgrading it would be a self-inflicted wound to one of the few remaining bridges between the two tours' calendars.

What is actually at stake

If the 2028 reshuffle relegates the Scottish Open to a lower tier, the field strength will thin, the Rolex Series designation will lose its shine, and the tournament's value as a links-Open tune-up will erode. If, on the other hand, the Tour uses the two-tier format to protect and elevate its strongest international events, the Scottish Open becomes one of the structural winners of the post-schism settlement. The next eighteen months of calendar planning, not this week's leaderboard, will decide which path is taken. Rahm's tee shot on Thursday will be a curiosity; the answer to McIlroy's warning is the headline that matters.

This publication treated the Scottish Open this week as a governance story wearing a golf shirt. The wire previews focused on form and course changes; the more durable read is the fight over what the 2028 format will preserve and what it will quietly demote.
