Let's take a look at Dustin Johnson's strokes gained golf stats to see how he won at the FedEx St. Jude Classic.
Total control week
TPC Southwind is tight and demanding, which theoretically works against the longest hitters. Johnson won it by clubbing down and prioritising position.
Strategy adjustment, not swing change.
Approach play decided it
With everyone playing from similar positions, the separation came from iron play. Closer approaches, more birdie looks, fewer stressful pars.
It is the same story that decides the majority of tournaments once you strip out the noise.
Takeaway
Being long is an asset you deploy, not an identity you defend.
Choose the tee shot that produces the best average score for the hole, and let the stats tell you which one that is.
