The Open Championship 2026 PGA DFS Perfect Lineup

The Open Championship is the last major of the season, and Ben Rasa framed this one as a wide-open field, with no golfer at the top of the DraftKings board you can bank on. The links test at Royal Birkdale rewards creativity, especially around the greens, and win equity is spread across a wide group of contenders. When no clear favorite separates, duplicating the highest-projected build becomes the real danger, because a flat field pushes the projection model to cluster lineups around the same names. So the DFS edge here is not guessing the champion; it is process: you build around a few golfers you trust and let the Stokastic single-lineup simulator do the combinatorial work around them. That is the perfect-lineup method from the show: Ben sets the three-golfer core, then the simulator finishes and stress-tests the build, and by the end you will see why the highest-projected build the tool returns is not automatically the best GPP lineup.

For the projections board updated through lock, our PGA DFS Picks hub carries the full field, and if you are new to running golf builds, how to use the Stokastic PGA Sims covers the mechanics this piece assumes.

In Summary

• The Build: three trusted build-around golfers, then let the single-lineup Sim complete and stress-test the other three spots. Average of $8,200 per remaining slot to fill.
• The Cornerstone: Tommy Fleetwood ($10,500) leads it off on five straight top-15 finishes and deep links pedigree, even with the fair knock that he rarely closes.
• The Mid-Range: Robert MacIntyre ($8,000), a Scot peaking after elite ball-striking at last week's Scottish Open, with three career top-10s at Opens.
• The Value: Hideki Matsuyama ($6,900) is rare salary relief in a major, carried by a world-class around-the-green game.
• The Lesson: the Sim's optimal completion (Rahm, Burns, Kim) posted a -4% Sim ROI at 129.5% ownership. Adding 5% randomness dropped ownership to 90% and flipped the build to a +25.5% Sim ROI. In a GPP, that ownership cut is the edge.

Start With A Cornerstone You Trust: Tommy Fleetwood ($10,500)

A perfect lineup needs a floor before it needs a ceiling, so the build starts at the top of the board. Tommy Fleetwood is a frequent guest of this exercise for one simple reason: he is extremely reliable, riding five straight top-15 finishes into the week with a mountain of Open Championship and links experience behind him. At $10,500 you would love a little more upside, and the honest concern is real. Fleetwood does not win his fair share given how often he is on the leaderboard; he gets to contention and then finishes 10th or 12th rather than lifting the trophy. Hold onto that idea, because it turns out to be the whole point of this slate. Even with the caveat, there is no question he belongs in the conversation, and at this price he is a comfortable golfer to lead off the lineup.

The Mid-Range Play: Robert MacIntyre ($8,000)

From that cornerstone we step down to the mid-range, where the goal shifts from floor to a golfer whose skill set fits the venue better than his salary suggests. Robert MacIntyre, "Bobby Mac," sits at a flat $8,000, and he checks the links box as well as anyone in the field. He is Scottish, he grew up playing in exactly these conditions, and Ben expects Royal Birkdale to play fairly calm, with little rain expected, tricky rather than brutal. That still favors a player who knows how to flight the ball and think his way around a links. MacIntyre owns five top-10s in majors, three of them at Opens, and he showed elite ball-striking last week at the Scottish. A dangerous player who may be peaking at the right time is precisely what you want in the middle of a build with no clear favorite.

The Value That Funds It: Hideki Matsuyama ($6,900)

Every perfect lineup lives and dies on the salary you save at the bottom, and a major is where that relief is hardest to find. Hideki Matsuyama at $6,900 is the exception. Normally he is the kind of quality name you build around first; this week he can be your last golfer in, and you rarely get a player of his class this cheap. The price reflects a lackluster season and middling form, no argument there. What survives the slump is the part that matters at an Open: his around-the-green game is still world class, and that creativity is what carries you when a links course forces awkward shots. His off-the-tee game finally showed some consistency at the Travelers, too. He is the last man in, and he is the reason the top of this lineup can afford to be expensive.

Now Let The Sim Finish The Job

Here is the payoff on that promise from the top. With Fleetwood, MacIntyre and Matsuyama locked, the Stokastic single-lineup simulator has $8,200 per spot to fill the last three. Click "complete this lineup" and it returns the three optimal plays by projection: Jon Rahm, Sam Burns and Si Woo Kim. That build projects for 385 points, the highest you can make around the three anchors. It is also where the flat field bites back. (One note on the numbers below: Sim ROI is the simulator's projected return across thousands of contest simulations, not a guaranteed profit.)

Build	Completion (last 3)	Total ownership	Sim ROI	Chance to win	Cash rate
Optimal By Projection	Rahm, Burns, Kim	129.5%	-4%	0.1%	27%
+5% Randomness	A different, lower-owned trio	90%	+25.5%	0.2%	27%

The row that matters is the second one. The projection did not need to improve; the ownership profile did. A single dial of 5% randomness cut the lineup's total ownership from 129.5% to 90% and swung the Sim ROI from -4% to +25.5%, while the chance to win actually ticked up. That is the entire GPP lesson in one screen: chalk and ownership move together, and in a tournament you do not get paid for owning what everyone else owns. Playing with projection and ownership is what turns a chalk build into a leverage build.

Why The Chalk Build Loses When The Field Is Flat

Circle back to Fleetwood, contending every week but rarely closing. The Open Championship treats the whole field a little like that: plenty of golfers with a real chance, no single one you can bank on. When win equity is spread that thin, the projection model clusters everyone on the same names, so the most-projected roster is also the most-duplicated one, and any of two dozen golfers can take it down. The randomness pass is not the tool being cute; it is the math of a flat field telling you to trade a sliver of projection for a lineup the rest of the pool will not have. For the deeper version of that trade-off, our breakdown of the Stokastic Sims ROI boost versus raw projection shows why the projection-max build is so often the wrong GPP play, and the cash-game workflow explains when you should flip the logic and chase floor instead.

The build we keep coming back to is the leverage one: Fleetwood, MacIntyre and Matsuyama as the trusted spine, then a low-ownership completion from the Sim rather than the chalk-optimal trio. Set your three anchors, run the PGA DFS projections and ownership in the DataHub, and let a few points of randomness build you a lineup with a chance to take down a major-sized field.

Worked Example: Turning The Chalk Build Into A Leverage Build

Here is the full sequence in numbers, start to finish, so you can copy it on your own slate:

1. Lock your three trusted names. Fleetwood ($10,500), MacIntyre ($8,000) and Matsuyama ($6,900) cost $25,400 of the $50,000 cap, leaving $24,600 and an average of $8,200 for the last three spots.
2. Complete for the max projection. The Sim fills Rahm, Burns and Kim for a slate-high 385 projected points, but at 129.5% combined ownership it grades out at -4% Sim ROI and a 0.1% chance to win.
3. Add 5% randomness and re-complete. The tool swaps in a completely different, lower-owned trio for 90% ownership, +25.5% Sim ROI and a 0.2% chance to win, doubling the win equity of the "optimal" build.

The takeaway: the projection-max lineup and the leverage lineup share the same three anchors and the same 27% cash rate, but the leverage version is the one better built to actually win a major-sized GPP.

FAQ

Who are the core PGA DFS plays for The Open Championship perfect lineup? The three trusted build-around golfers are Tommy Fleetwood ($10,500), Robert MacIntyre ($8,000) and Hideki Matsuyama ($6,900). Fleetwood is the reliable high-priced pick, MacIntyre is the links-bred mid-range play, and Matsuyama is the value that funds the top of the roster.

Why not just play the highest-projected lineup? Because the highest-projected build (Rahm, Burns and Kim around the core) also carries the highest ownership, 129.5% combined, and posted a -4% Sim ROI in the single-lineup simulator. When the field is this flat, the most-owned lineup is the most fragile.

What does the 5% randomness setting actually do? It lets the Sim trade a sliver of raw projection for a lower-owned build. On this slate it dropped total ownership to 90% and flipped the Sim ROI to +25.5%, which is the leverage you want in a large-field tournament.
