GENESIS INVITATIONAL STATISTICAL MODEL 2026

GENESIS INVITATIONAL STATISTICAL MODEL 2026

The PGA Tour’s West Coast swing reaches its most traditional and strategically demanding stop this week at the Genesis Invitational, where classic architecture replaces desert fireworks and precision outweighs pure aggression. Played at historic Riviera Country Club in Pacific Palisades, California, this Signature Event returns to its longtime home after last year’s temporary move and arrives during the course’s 100th anniversary season. Known as one of the purest tests in professional golf, Riviera blends subtle design, strategic angles, and relentless decision-making, earning universal respect from players despite having no water hazards and few visual tricks. Here, scoring opportunities exist, but only for players willing to fully commit to every shot.

After consecutive weeks of unique formats, the tournament follows a traditional structure with a limited Signature Event field and a 36-hole cut to the top 50 and ties plus anyone within 10 shots of the lead. Riviera plays as a par 71 stretching just over 7,300 yards, but it consistently ranks among the toughest non-major venues on Tour. Winning scores typically settle in the low-to-mid teens under par, and the course’s predictability stands out — experience matters here more than almost anywhere else, with most champions requiring multiple prior starts before finally solving its challenges.

Off the tee:
Riviera demands strategy rather than brute force. Fairways narrow in key landing areas, doglegs force shaped tee shots, and Kikuyu grass creates unpredictable lies that punish poor positioning even without traditional hazards. Distance still provides an advantage — longer players can attack with shorter irons — but placement is critical, as the best angles into greens often come from the riskiest lines. Good Drive Percentage consistently separates contenders, rewarding players who can recover even when missing fairways. This is a thinking player’s driving test, where shaping the ball both directions matters more than simply swinging hard.

Approach:
This is fundamentally an iron-play examination. Firm Poa annua greens repel marginal shots, and nearly three-quarters of approaches come from 150 yards or longer, placing heavy emphasis on mid- and long-iron control. Players must manage trajectory, spin, and landing angles to access correct tiers while avoiding short-sided misses that quickly lead to bogeys. Riviera’s large greens paradoxically produce one of the lowest GIR rates on Tour due to false fronts, contours, and awkward angles. SG: Approach remains the most predictive stat, especially for players capable of controlling distance under pressure and consistently leaving uphill putts.

Around the green and putting:
Missed greens immediately expose weaknesses. Deep bunkers rank among the most penal on Tour, and Kikuyu rough around the greens makes clean contact difficult, forcing creativity and precise technique. Scrambling requires touch, but putting ultimately defines survival. Riviera’s Poa annua greens are among the hardest surfaces on Tour, particularly inside 15 feet, where subtle movement and late-day bumpiness create constant uncertainty. Three-putt avoidance and lag putting become critical, and even elite ball-strikers can lose ground quickly if they fail to manage speed on the large, undulating complexes.

Model focus:
SG: Approach, SG: Around the Green, Good Drive %, and Bogey Avoidance. Riviera is not a random scoring week, it is one of the most predictive courses on the schedule. Complete ball strikers with patience, course experience, and comfort shaping shots in demanding conditions consistently rise to the top.

One & Done:
I am excited to announce that I have added some very advanced simulations for the increasingly popular One & Done format. If anyone has any questions about how the One and Done simulation works, all are welcome. While the model itself is and always will be free, if you want the latest and greatest features, updates, and opinions from yours truly, join my Patreon! Even if you’re just here to check out the model, I appreciate you—it's really cool knowing people enjoy something I’m passionate about. Ask away if you have questions!

DFS players: head to the Model tab for DraftKings and FanDuel salaries, ownership projections, and live updates starting Tuesday. The Lineups tab and Leverage tab work together to help you track your DFS exposures. The Course History, Recent Form, and Proximity tabs breakdown those individual categories you see in the Model tab.

The Betting tab shows real-time odds, sorted by model rank. Want to change the sportsbook? Make a copy—but know that odds stop auto-updating in copies.

The Live Leaderboard shows each golfer’s real-time score, strokes gained breakdown, and rank vs. their model rating. Live R² values also update by the minute, so you can see which stats matter most as the week unfolds.

The Matchups tab pulls all tournament/round head-to-heads and 3-balls. Bet Scores highlight the best value, with suggested unit sizing and tracked results. This feature only works on the original sheet, but make a copy and use the Custom Matchups tab to manually input matchups and 3-balls.

!!!! NEW !!!!

The brand new One and Done tab introduces a next-generation simulation engine, running 1,000 full PGA season simulations with 100 event-level simulations embedded inside each season. It dynamically optimizes pick paths by weighing win equity, future opportunity cost, and long-term leverage instead of chasing single-week results. Every Tuesday, an advanced ownership forecast layer is injected into the model, reshaping pick values based on projected usage and unlocking contrarian paths with higher season-ending upside.
