TPC Sawgrass Hole 17: The Grass, Irrigation and Agronomy Behind Golf's Most Famous Island Green

Golf's most photographed hole, explained by irrigation people

Every March, millions of viewers watch the best players in the world take on 150 yards of water to reach a green of barely 4,000 square feet: that's the 17th hole on the Stadium Course at TPC Sawgrass in Ponte Vedra Beach, Florida, host of THE PLAYERS Championship, scheduled for March 11-14, 2027. It gets talked about for the drama — balls in the water, ruined scorecards — but almost nobody covers what happens under the surface: what grass is actually growing there, how you irrigate a green that's essentially cut off from the rest of the course, and how an entire course gets timed to peak in one specific week in March.

We're covering it from a different angle than the golf press usually does: the irrigation design side. The numbers and practices below come from real agronomy sources (Golf Course Industry, BIGGA, GolfPass), not clubhouse folklore.

Why there's an island green in the first place

Hole 17 wasn't an accident. Designer Pete Dye, working with his wife and design partner Alice Dye, laid it out in 1981 using sand excavated to build the Stadium Course's lakes and mounding — and ended up leaving that natural island sitting in the water instead of filling it in. The result — a par 3 that looks tiny (it plays anywhere from 137 to 150 yards depending on pin position) but feels enormous under pressure — became the defining image of modern televised golf.

The green measures roughly 4,000 square feet, with less than 6 feet of margin between the putting surface and the water at the tightest point. There's essentially no room for a mishit, which is exactly what makes the maintenance as delicate as the shot itself.

What grass is actually on hole 17

The green is planted with TifEagle Bermuda, a fine-bladed hybrid cultivar widely used on tournament greens for how well it tolerates extremely low mowing heights. For winter and the tournament window, though, it's overseeded with Poa Trivialis blended with bentgrass — and according to club general manager Derek Sprague, the greens actually run faster in March than on pure Bermuda, on top of showing a more uniform green on camera.

Fairways and tees are Celebration Bermudagrass, overseeded in autumn with Champion Fine Ryegrass (a typical blend is 80% perennial ryegrass to 20% fine fescue). It's the same principle used across plenty of Southern U.S. courses: summer Bermuda goes dormant and browns off in the cold, so a cool-season grass gets overseeded on top to guarantee a bright green carpet right when tournament season hits.

How you irrigate — and drain — a green surrounded by water

An island green creates a problem a normal green doesn't have: the water around it doesn't do the irrigating — if anything, the real work is drainage and precise moisture management, keeping a green that already sits at lake level from staying permanently saturated. TPC Sawgrass handles this with zone-based irrigation and regular usage audits, an approach that's essentially the same idea — at a vastly bigger scale — we recommend for any home garden with zones that need watering independently (more detail in /enHydrozones: split your garden to irrigate better).

One detail rarely reported but genuinely interesting from an agronomy standpoint: drainage water from the course isn't wasted, it's captured and piped back into the irrigation ponds for reuse — a closed loop that cuts down on how much fresh water the course needs to pull from outside sources. It's the same principle, at home scale, as a rain barrel feeding your garden's irrigation system.

Since 2025, agronomic responsibility for the course has passed to Lucas Andrews, who took over from Jeff Plotts after his 10 years leading the maintenance team — a leadership change that lands right as the course gears up for the 2027 tournament.

The seasonal maintenance calendar, month by month

Since THE PLAYERS Championship locked in a permanent March date (starting in 2019), TPC Sawgrass has had to run a far tighter maintenance calendar than a typical course, built around two scheduled closures a year.

The first closure, late October into mid-November, is for intensive overseeding: the course flips from dormant Bermuda brown to bright cool-season green, right in time for winter and the March tournament. The second closure, early June into early July, runs the process in reverse — clearing out the now heat-stressed ryegrass and letting pure Bermuda take back over for Florida summer.

How you actually mow — and care for — a green that's an island

On paper, hole 17 is a green like any other. In practice, every single task — mowing, feeding, aerating — needs logistics no other green on the course requires: the maintenance team gets out to the island by boat every single day to tend it, and the crew mowing it uses turning boards so the mower's wheels don't rut the one green on the course with zero margin for a steering mistake.

It's an almost ritualistic level of care: staff are specifically trained on the spatial awareness a green like this demands, where a wrong step means, quite literally, ending up in the water with the equipment.

What to expect from the course for the 2027 edition

With the tournament locked in for March 11-14, 2027, the course will be at peak overseed condition: faster-than-usual greens, thicker rough thanks to the ryegrass, and fairways in a bright green that reads perfectly on camera against the blue water ringing hole 17. Florida's March weather — the occasional cold front, shifting wind — remains the least controllable variable, even with flawless agronomy behind it.

For anyone following the tournament closely, hole 17 will likely be just as decisive as ever: on a green of barely 4,000 square feet with water on three sides, the gap between a birdie and a double bogey comes down to a few feet — on grass that's been groomed for months specifically for that March weekend.

What a home irrigation setup can actually learn from this

Nobody needs to overseed their lawn twice a year or take a boat out to mow it, but two principles from Sawgrass translate directly to a home garden. The first is independent zone irrigation: an island green managed with millimeter-level precision and a garden with a lawn, hedges and flower beds have the same underlying problem — different areas need different amounts of water, and treating them as one block wastes water and stresses the plants. We break this down with real numbers in /enHow to set irrigation run times by soil type.

The second is water reuse: Sawgrass' closed loop of draining water back into the irrigation ponds is, at scale, the same idea as a rain barrel or a sensor that skips watering when the soil's already saturated — practical details in /enFive ways to cut irrigation water use by up to 40% and /enRain sensor for irrigation: legal requirement and how it works.

Frequently asked questions about hole 17

Is hole 17 actually an island? Yes — the green is fully surrounded by water and reachable only by a pedestrian bridge; the maintenance crew uses a boat for daily upkeep.

What grass is on the 17th green? TifEagle Bermuda as the base, overseeded with Poa Trivialis and bentgrass for winter and the March tournament window.

Why is THE PLAYERS Championship played in March? The tournament has had a permanent March date since 2019, when the PGA Tour reshuffled its season and moved the PGA Championship to May.

Are the greens tougher during the tournament because of the overseed? Yes — according to the club's general manager the greens run faster than on pure Bermuda, and the thicker overseeded rough punishes missed shots more severely.

The short version

Behind the drama of hole 17 sits months of agronomic work that starts long before the tournament: two scheduled closures a year, a seasonal grass swap timed almost to the day, and an irrigation and drainage system that has to manage a green practically surrounded by water without ever letting it stay waterlogged. THE PLAYERS Championship 2027, March 11-14, will be — as always — the one week where all of that invisible work becomes visible on camera.
