Gary Woodland apparently has done what is required to take his game to the next level, in his case win a major. His best before winning at Pebble had been just two top-10 finishes in his major career (T-6, 2018 PGA at Bellerive; T-8, 2019 PGA at Bethpage).
I like what he and his coach Pete Cowen are doing with his shortgame, he has the shaft more vertical at address which enables him to use the bounce and slide through the grass easier. He showed composure and when he needed courage to pull off the tough shot, he listened to his caddie when he told him to be aggressive on 14 and go for it with his 3 wood .With his work with putting expert Phil Kenyon his approach became simplified, then he had less tension in his pre-putt routine which lessened his anxiety.
Gary is a super talented athlete but talent alone doesn’t do it, I give credit to him for working on the correct balance of physical and mental to win the US Open.
