CADDIE Course Preview · RBC Heritage 2026 · Apr 16–19 · Hilton Head Island, SC
Harbour Town Golf Links
PAR 71 · 7,213 YARDS · $20M SIGNATURE EVENT · 82-PLAYER FIELD · NO CUT
Harbour Town is the most statistically legible course on the PGA Tour. The skills it rewards are narrow, consistent, and documented across decades of data. What wins here is almost never a surprise to a well-built model.
01 — Course Architecture
What makes Harbour Town different
Positional golf, not power golf
Being in the right rough is often better than the wrong part of the fairway. Harbour Town has more tree-blocked approach angles than almost any other Tour stop. Shot shape and positional awareness matter far more than distance — the course plays to just 280 yards average driving distance versus a Tour mean of 292.
The second-smallest greens on Tour
At 3,700 sq ft average — roughly half the Tour average of 6,600 sq ft — only Pebble Beach has smaller greens on the PGA Tour. Missing greens here is not a mistake to avoid; it's an inevitability to manage. The field GIR rate is 58%, one of the lowest on Tour.
Wind is the primary variable
More rounds at Harbour Town have been played in winds over 17 mph than under 10 mph over the last 20 years. Calm conditions produce birdie fests near the tournament record of -22. Gale-force days make scrambling and par the priority. Kevin Roth's (@KevinRothWx) forecast integrates directly into CADDIE projections.
Freshly rebuilt greens — new surface in 2026
Every green was torn out and rebuilt after the 2025 event as part of Davis Love III's six-month restoration. Grass type is unchanged — TifEagle Bermuda overseeded with Poa Trivialis, running 11–11.5 on the Stimpmeter. But these are brand-new surfaces that no Tour player has yet competed on. Course history remains the strongest signal; green-reading patterns carry a small unknown.

2026 — First year on restored course
Harbour Town closed in May 2025 immediately after last year's event for a full six-month restoration led by Davis Love III. Every green, bunker, and bulkhead was rebuilt. Tees were laser-levelled. Some pot bunkers were added or reshaped. Cart paths were rerouted. The grass types are unchanged — TifEagle Bermuda on the greens, Celebration Bermuda on fairways and rough — but 2026 is the first time PGA Tour players will compete on the new surfaces. Historical course data remains the strongest available signal. Green speed and surface behavior carry a small but real unknown.
Crossover Courses — Documented Correlation
The courses with the strongest documented success correlation to Harbour Town are Sea Island / RSM Classic, Sedgefield / Wyndham Championship, and Innisbrook / Copperhead (Valspar) — all Pete Dye-influenced, tree-lined, short tracks that reward shot shape and scrambling over raw power. 12 of the 17 winners from 2009 onwards previously finished top 10 at Copperhead.
02 — What the Data Says
The SG hierarchy at Harbour Town
Over the past six years, SG: Approach has been nearly three times more predictive than SG: Off the Tee among the top-5 finishers. This is one of the most statistically clear course signatures on Tour.
SG: Approach
Dominant — 3× more predictive than OTT
SG: Tee-to-Green
Ceiling metric — every winner ranked top 11
SG: Around the Green
The separator in close finishes
SG: Putting
Nice-to-have — Spieth won ranked 60th
SG: Off the Tee
Near-irrelevant — winners ranked 1st to 50th
The stat that does not matter: SG: Off the Tee
The last eight winners ranked 1st, 4th, 20th, 34th, 50th, 32nd, 49th, and 30th in SG: OTT for their winning week. The 2019 champion ranked dead last in the field. If you are filtering players up or down based on driving, you are using the wrong signal for this course.
03 — Hole-by-Hole Analysis
Where scores are made and destroyed
12 of 18 holes play over par annually. Scoring concentrates on a handful of specific holes — capturing those birdies while limiting damage on the danger holes is the weekly formula.
HOLE 1 · PAR 4 · 422 YDS
Opening corridor
Tight tee shot through a 30-yard oak chute. Trees block approach from the wrong angle. Extended to 422 yards in 2026 — no longer a wedge opener for most.
HOLE 2 · PAR 5 · 550 YDS
Eagle opportunity
Reachable par-5 with a 2.7% eagle rate. One of three par-5 scoring engines. Players who take the left side off the tee open up the diagonal green in two.
HOLE 3 · PAR 4 · 385 YDS
Positioning hole
Straightforward by Harbour Town standards. Short iron in from the right side of the fairway. A place to make routine par and stay patient.
HOLE 4 · PAR 3 · 195 YDS
Water left of the green
Lagoon wraps the left half of the heart-shaped green. A rise on the back edge catches overhit shots but kicks them toward water. Precise club selection is the only answer.
HOLE 5 · PAR 5 · 569 YDS
Front-9 scoring engine
Players go for the green in two just over 50% of the time but convert less than 10%. Eagles rare at 1.9%. Still a must-make birdie — plays to a doughnut-shaped green complex moved by Dye in 1999.
HOLE 6 · PAR 4 · 431 YDS
Angle game
Extended to 431 yards in 2026. Right side of the fairway opens the approach. Left miss brings trees directly into play on the second shot.
HOLE 7 · PAR 3 · 217 YDS
Long par-3 into wind
Extended to 217 yards in 2025 and kept for 2026. Plays into the prevailing wind. Bunkers surround a tiny green. Club selection under pressure separates the field.
HOLE 8 · PAR 4 · 473 YDS
Lowest birdie rate: 9.5%
Longest par-4 on the course. Fairway curls left — drives right of center leave a live oak blocking the approach. The small, minimally-defined green is among the hardest to hit on Tour.
HOLE 9 · PAR 4 · 332 YDS
Highest birdie rate: 28.3%
Highest birdie rate among par-4s. Driveable for longer players who take the correct right-side line. Pot bunker back-center punishes aggressors who overcook it.
HOLE 10 · PAR 4 · 420 YDS
Tree-blocked approaches
Players are frequently blocked out even from the fairway. Thomas made 3 of his 5 bogeys on holes 10 and 11 in 2025. Getting through this hole cleanly is a weekly requirement for contenders.
HOLE 11 · PAR 4 · 435 YDS
Sub-13% birdie rate
Paired with No. 10 as the most damaging two-hole stretch on the back nine. Both holes rank among the six toughest on the course. Playing 10–11 in even par is a meaningful edge.
HOLE 12 · PAR 4 · 370 YDS
Short par-4 reset
One of the shorter par-4s on the back. Management off the tee. Tiny green still demands precision — ARG skill rewarded on inevitable misses.
HOLE 13 · PAR 4 · 375 YDS
Demanding approach
One of the most unforgiving approach shots on the property. Wrong miss leaves scrambling from positions where up-and-down is nearly impossible.
HOLE 14 · PAR 3 · 182 YDS
Water surrounds the target
Minimal margin between green and hazard. One of five holes — 4, 8, 14, 17, 18 — where water tightens the margin to near-zero. Wind amplifies every club selection error.
HOLE 15 · PAR 5 · 570 YDS
Reachable par-5
Originally a definitive three-shotter. Equipment has made it reachable for longer players who drive the right side of the narrow fairway. Green was enlarged by Dye in 1999. Late-round birdie opportunity.
HOLE 16 · PAR 4 · 360 YDS
Course opens up
After 15 holes of trees and corridors, Harbour Town bursts onto tidal marsh. Shorter par-4 with a wider landing area — one of the more gettable scoring holes on the back nine.
HOLE 17 · PAR 3 · 185 YDS
Into the headwind
Plays southwest — almost always directly into the wind off Calibogue Sound. Water comes into play here for the first time. Par in the final round is a hard-earned result.
HOLE 18 · PAR 4 · 478 YDS
The lighthouse closer
Entire left side guarded by Calibogue Sound. OB stakes right. Wind off the water. Sub-13% birdie rate. Three of the last four years ended in playoff — often decided on this green.
Must-make birdie holes
#2 and #5 (par-5s, front nine) and #15 (par-5, back nine) are the three scoring engines. #9 at 28.3% birdie rate is the best par-4 opportunity on the course. #16 is the gettable back-nine closer. Players who capitalize on these five holes separate fast from the field.
Bogey avoidance — where weeks end
#8 (9.5% birdie rate) and #18 (entire left over water, OB right) are the two execution holes that end contention. #10–11 is where Thomas absorbed 3 of 5 bogeys in 2025. A double on this stretch is a tournament-defining mistake.
04 — Winner Blueprint
What the last 8 champions shared
Eight years of winner data reveals a consistent statistical fingerprint. Three factors appear in nearly every champion. One is consistently irrelevant.
01
SG: T2G — top 11
Every winner 2018–2025
No champion has finished outside the top 11 in tee-to-green. This is the non-negotiable floor. Players whose T2G is trending below their mean going into this week are structurally ceiling-capped.
02
SG: APP — top 18
6 of 8 winners inside top 10
Approach is 3x more predictive than OTT. Hitting the second-smallest greens on Tour from the correct angles is where the tournament is won. This is the number one stat to prioritize.
03
Scrambling — top 16
15 of 17 years: leader → top 11
Misses happen on 42% of holes. What separates the field is converting those misses. In 2022, every single top-11 finisher gained strokes from the sand for the week.
| Year | Champion | Score | OTT | APP | ARG | T2G | PUTT | Scram |
|---|
| 2025 | Justin Thomas▼ | -17 | 49 | 5 | 15 | 11 | 3 | 8 |
| 2024 | Scottie Scheffler▼ | -19 | 1 | 1 | 31 | 1 | 36 | 1 |
| 2023 | Matt Fitzpatrick▼ | -17 | 32 | 7 | 10 | 3 | 20 | 4 |
| 2022 | Jordan Spieth▼ | -13 | 4 | 10 | 5 | 1 | 60 | 6 |
| 2021 | Stewart Cink▼ | -19 | 20 | 2 | 5 | 1 | 25 | 4 |
| 2020 | Webb Simpson▼ | -22 | 34 | 8 | 33 | 7 | 2 | 27 |
| 2019 | C.T. Pan▼ | -12 | 50 | 18 | 7 | 11 | 5 | 16 |
| 2018 | Satoshi Kodaira▼ | -12 | 30 | 12 | 8 | 9 | 1 | 12 |

05 — DFS & Betting Framework
How to filter your targets this week
Run every player through this framework. The more boxes they check, the stronger the play. CADDIE's highest-confidence targets clear all five.
01
SG: T2G — must rank inside top 20 in recent form
Every winner since 2018 finished inside the top 11 in T2G for the week. Players trending below their season mean in T2G going into this event are ceiling-limited regardless of salary.
⚠ OTT rank is irrelevant. Do not use it as a positive or negative signal.
02
SG: APP — minimum top 25, target top 15
Approach is three times more predictive than OTT among top-5 finishers. Look for recent form, not just season-long averages. The second-smallest greens on Tour demand elite iron accuracy from the correct angles.
⚠ Weight recent approach performance more heavily than season-long rank — form matters here.
03
Scrambling % — 75%+ or trending upward
In 15 of the last 17 years, whoever led the week in scrambling finished inside the top 11. In 2022, every top-11 finisher gained strokes from the sand. Misses happen on 42% of holes — what players do with those misses determines the leaderboard.
⚠ Good ball-strikers with weak ARG numbers get exposed at Harbour Town specifically and repeatedly.
04
Course history — at least one top-25 finish at Harbour Town
Course knowledge is disproportionately valuable here. Outside Augusta and Bay Hill, Harbour Town has some of the most predictive course history on Tour. The angles, miss zones, and surface reads are learned.
⚠ First-time starters are a fade without documented RSM Classic, Wyndham, or Innisbrook form.
05
No chronic Bermuda putting weakness
TifEagle Bermuda overseeded with Poa Trivialis creates a specific surface. Players with documented Bermuda putting struggles at Sea Island, Sedgefield, or Kapalua should be weighted down.
⚠ Putting is not required to win here — Spieth ranked 60th SG: PUTT in 2022 and won. But chronic Bermuda misfits rarely contend.
Coming Wednesday
Weather-adjusted projections, DFS picks, and the full betting card — including outrights, top-10s, top-20s, and a parlay — drop Wednesday via CADDIE. All picks are built on the framework above.
