His strategy of laying back to make shortgrass lies more probable (he hit 10 of 14 fairways, with two of his misses in the manageable first cut) meant he was hitting mid or long irons into many of the greens.
The elegant six-foot 15-year-old from Hawaii found some difficult spots in the rough, but her power saved her on several occasions, although a fourth dropped shot came at the 16th when a wedge from the thick rye grass sank into more trouble short of the green.
It has similar tight fairways but the rough is not penal, and the dome-like greens form the main defence, surrounded by close-cropped grass, placing an emphasis on accurate irons and a top-class short game.
