PGA DFS lineup optimizer
Golf is a different puzzle from football: six golfers, no teams, no games to stack — just a field, a salary cap and the question of how many different ways you want to be right about who contends. Martian Flow builds PGA lineup portfolios on DraftKings and FanDuel.
Who it is for
- Golf DFS players entering several lineups into a tournament.
- Players who want exposure to a wide set of golfers without hand-building every combination.
- NFL players adding golf weekends who want the same controls in both sports.
How PGA lineups differ
A PGA lineup is six golfers under the salary cap. There is no correlation between teammates to exploit, so the work is in exposure and diversification: how often each golfer appears, how many lineups are built around the top of the field versus value plays, and how different the lineups are from each other.
Golfers who miss the cut stop scoring after two rounds, which makes a lineup's floor depend on how many of its six make the weekend. The projections account for that.
Projections and withdrawals
Published PGA tournaments carry Martian Flow golf projections, and you can upload your own. Golfers who withdraw can be excluded and affected lineups rebuilt.
How Gus works
Gus is the analyst built into Martian Flow. He reads the slate you have open — the projections, salaries, game lines, injury and inactive statuses, and recent public reporting — and answers questions about it in plain language: who the value plays are, which game sets up best to stack, how much exposure a player deserves in a 150-lineup portfolio.
When you ask Gus to build, he does not hand you lineups from a black box. He writes a plan — exposures, stacks, Captain or MVP targets — shows it to you, and only builds once you approve it. Every instruction he gives becomes a visible rule in the builder, next to the ones you set yourself, and yours win when the two disagree.
Player exposure
Exposure is how often a player appears across your lineups. Set a minimum, a maximum or an exact figure for any player, as a percentage or a lineup count. On single-game slates the Captain or MVP seat has its own exposure, separate from the player's overall share.
With no exposure rules at all, Martian Flow keeps any one player from taking over the portfolio on its own, and the Balanced strategy holds unruled players to about a third of your lineups.
Locks and exclusions
Lock a player into every lineup or exclude him from all of them in one click. On single-game slates you can lock or ban a player from the Captain/MVP seat specifically. Players ruled out, placed on injured reserve or declared inactive are removed automatically, and if news breaks after you build, you can rebuild only the lineups that are affected.
Portfolio review and diversification
Martian Flow builds a portfolio, not the same lineup 150 times. Lineups are selected together, so the set is diversified by design: exposure is spread, near-duplicates are avoided, and different game scripts get coverage.
After the build, Portfolio Review shows every player's exposure, how the portfolio stacks, how similar the lineups are to each other, whether each of your rules was met, and highly rated players the build left out without a reason you gave.
Contest-ready CSV export
Download your lineups as the upload file DraftKings or FanDuel expects, or fill in the contest's own entries file so every entry is replaced in one upload. Lineups are checked against the site's roster and salary rules before they are exported.

Questions
- Does Martian Flow stack golfers?
- No — golf has no teams or games to correlate, so there is nothing meaningful to stack. The work in PGA is exposure and diversification, and those controls are the same ones you use in NFL.
- Do I need my own projections?
- No. Published NFL and PGA slates come with Martian Flow projections built in. If you have your own numbers you can upload them, and the optimizer uses yours instead.
- Does Martian Flow guarantee winning lineups?
- No. No tool can. Daily fantasy is decided by games played by real people, and most entries lose. What an optimizer does is build lineups that follow your reasoning and are constructed well — valid, diversified and correlated — so that when your read on the slate is right, your lineups are positioned to benefit.
- Is Martian Flow affiliated with DraftKings or FanDuel?
- No. Martian Flow is independent and is not endorsed or sponsored by either site. It produces the files each site accepts for lineup upload.
