Agronomy—aka fast, hard running fairways—is the go-to faux argument for preserving distance standards should a Harry Higgs or Craig Stadler come along and blow the notion that “athletes fuel distance spikes”.
Certainly today’s generally more fit and better fit players generate increased clubhead speed, and, therefore more distance.
On the surface, agronomy as a distance booster should be a tougher sell since courses have never been greener. One very famous annual major stop, Augusta National, unapologetically presents fairways mown toward tees to slow down drives.
For now, don’t do a deep dive on 2020 yet because the numbers are not all in and the sample size differs from year’s past now that all PGA Tour tees have a Trackman. Look instead to the previous 13 years when the PGA Tour’s amazing ShotLink started measuring carry and distance on the two measuring holes per round.
Those fancy launch monitors peskily track carry while ShotLink documented the final distance of the drive.
