● The Math of 59 on Tour
Shooting 59 is one of the rarest feats in sports. On a standard Par 70 course, a player must post 11 under par. On a Par 71, 12 under par is required; on a Par 72, it demands 13 under par.
- Required Average Birdie Rate ~61% of Holes
- Bogey Allowance Usually 0 (Max 1 if Multiple Eagles)
- Front 9 Baseline for Contention 6-under (29 or 30)
● Historical PGA Tour Sub-60 Club
Fewer than 15 players in PGA Tour history have shot 59 or lower in official competition. Jim Furyk holds the all-time record with a 58 at TPC River Highlands (2016).
- Jim Furyk (2016) 58 (-12, Par 70)
- Al Geiberger (1977) First 59 (-13, Par 72)
- David Duval (1999) 59 (-13, Won Tournament)
- Justin Thomas (2017) 59 (-11, Waialae CC)
● Closing Pressure on 17 & 18
When a player reaches 10-under through 16 holes, they enter "59 Watch." The final two holes require precise distance control and nerve to hold off standard par or convert the closing birdie.
- David Duval (1999) Eagle putt on 18 to shoot 59
- Scottie Scheffler (2020) Birdies on 14, 15, 16, and par finish
- Poston / Biltmore Chase Pushed birdie run into final stretch
