SOUTHAMPTON, N.Y. — The last time the U.S. Open rolled through these parts, in 2018, Zach Johnson uttered a line that became the stuff of golf Twitter lore: “They’ve lost the golf course.” Johnson was referring, melodramatically, to the USGA’s management of Shinnecock Hills’ greens, which by the end of a dry and windy Saturday were crispier than burnt pita. Eight years later, the Open is back, and with a forecast that could make the previous edition look like, well … a breeze.
