The spotlight returns to RBC Heritage this week, and with it comes renewed fascination with one of golf’s most intriguing benchmarks, the RBC Heritage records for the lowest rounds ever posted at Harbour Town Golf Links.
As defending champion Justin Thomas tees it up once more, his name sits firmly among those who have achieved something rare on this demanding coastal layout, a round of 61 that still stands as the lowest score in tournament history.

RBC Heritage records and the magic number of 61
For more than half a century, Harbour Town has tested the world’s best with narrow fairways and an emphasis on accuracy. Power alone does not unlock this course. Instead, it rewards discipline, control and a sharp eye for positioning.
That is why 61 remains such a revered number in the RBC Heritage records. It is not just low, it is exceptionally difficult to achieve on a course that rarely yields to aggression.
Justin Thomas and the record-tying round that changed everything
Thomas’ 10 under par 61 in 2025 was a performance built on precision rather than spectacle. Four birdies in his opening five holes laid the groundwork before he turned in a flawless 6 under 30.
A bogey at the 10th might have unsettled others, yet Thomas responded with authority. Birdies followed at the 12th, 13th, 15th and 16th, all from inside 15 feet, before a stunning 37 foot putt dropped at the par 3 17th.
A 5 foot chance at the last to claim the record outright slipped away, but the round still secured his place in the history books.
“I just played really solid. I feel like I didn’t do anything crazy. I just drove the ball well, which is very, very important out here, and I felt like it was just one of those days I put the ball in a spot that I had a lot of good numbers.”

RBC Heritage records holders who shot 61
Thomas joined an exclusive group. David Frost was the first to reach 61 in 1994, followed by Troy Merritt in 2015. Both achieved the feat in the second round, highlighting just how rare it is to produce such a score under any conditions at Harbour Town.
Why breaking RBC Heritage records is so difficult
Harbour Town is not designed for easy scoring. Its tree lined fairways, small greens and coastal winds demand patience. Players must think their way around rather than overpower it.
That context makes every 61 even more remarkable. It is not just a hot putting day, it requires complete control from tee to green.
The near miss that denied Thomas sole possession
Even in a near perfect round, there was one fleeting moment. Thomas stood over a 5 foot birdie putt on the 18th that would have given him sole ownership of the record.
When it slid past, the reaction was brief. The bigger picture remained clear. He had delivered one of the finest rounds the tournament has ever seen.
RBC Heritage records beyond 18 holes
While the single round mark draws headlines, the 72 hole scoring record carries equal weight. That honour belongs to Webb Simpson, who reached 22 under par in 2020 to set the standard for sustained excellence across four rounds.
He narrowly edged Abraham Ancer, underlining how fine the margins can be even in record breaking weeks. Before that, Brian Gay posted 20 under par in 2009, a performance that also produced a record 10 shot victory margin.
Can history repeat for Justin Thomas in 2026
Thomas arrives this year with confidence shaped by last season’s success. His journey to that title included a narrow defeat to Viktor Hovland earlier in the campaign and a frustrating week at Augusta, making his Harbour Town triumph all the more significant.
“Yeah, extremely different. It’s a totally different style of golf. I’ve been playing really well, really solid. Felt good about things. I just didn’t play well last week. Put some really good work in I felt like the couple days leading into the start today, and I felt prepared. It was just about going out and doing it, and it was nice to do so.”

RBC Heritage records in focus as a new chapter begins
As the 2026 tournament unfolds, the numbers remain a constant presence. The RBC Heritage records are more than statistics, they are milestones that define careers and shape legacies.
Thomas has already secured his place among them. The question now is whether he can go one step further and stand alone at the top of the leaderboard once again.
