The 2024 US Open has by far been the toughest tournament of the 2024 season so far. The Pinehurst course #2 has been particularly hard for golfers to navigate, with even the likes of Scottie Scheffler and Xander Schauffele struggling.The Pinehurst Course has been watered on a daily basis, much to the dismay of many of the fans. The ground maintenance staff that has been watering the course in the mornings has garnered criticism from the fans for doing so. On Day 3, one of the volunteers at the US Open, who was watering the course, got booed by the audience in the grandstands.Instead of taking this as a negative thing, the US Open volunteer said that it was the 'coolest thing' that ever happened to her."Getting booed by the grand stands at the @usopengolf for putting water down on the greens might be the coolest thing to ever happen to me"Only 15 golfers have managed to stay under par after 2 days at the US Open. Scottie Scheffler barely managed to make the cut for the event.
