Here’s the honest answer up front: The Open Championship has no official record for most birdies in a tournament. The R&A’s record book tracks scoring — lowest rounds, lowest totals, largest margins — but it has never published tournament-long birdie counts the way the USGA does for the U.S. Open, where Rickie Fowler’s 23 birdies in 2023 stand as the official mark, or the PGA Tour, where Im Sung-jae’s 34 at the 2024 Sentry is the all-time record.
What The Open does have is a set of verified birdie feats that serve as the benchmarks. The most famous belongs to Henrik Stenson, who made ten birdies in his final-round 63 at Royal Troon in 2016 — prompting runner-up Phil Mickelson’s unprintable reaction on the 18th green — on the way to a record 72-hole total of 264, twenty under par. And the single-round standard was set at this week’s venue: Branden Grace’s 62 at Royal Birkdale in 2017, eight birdies without a bogey, remains the lowest round ever shot in a men’s major.
The chart below collects every verified birdie and scoring record at The Open, plus how the other tours track the tournament-count question this page is really asking.
The Closest Thing to an Answer
If you need one number, the defensible ones are these: ten birdies is the most a champion has made in a single Open round (Stenson, 2016), eight is the most in the record-low 62 (Grace, 2017), and twenty under par is the deepest anyone has finished across 72 holes (Stenson again). Anyone claiming a specific tournament-long birdie total as “the Open record” is working from unofficial counting — treat those numbers with suspicion, because the R&A doesn’t certify them.
The Bottom Line
The Open doesn’t keep an official most-birdies-in-a-tournament record — the U.S. Open (Fowler’s 23 in 2023) is the only major that does. The Open’s birdie benchmarks live in its scoring records instead: Stenson’s ten-birdie 63 and 264 total from the great Troon duel of 2016, and Grace’s eight-birdie 62 at Royal Birkdale, the course hosting the 2026 Open right now.
