Earlier in the week, superintendent Zach Reineking told USGA officials that if rains came, those tall fescues would lay down, rendering them unplayable. The irrigation system isn’t directly to blame. The spray heads are set inwards to keep the main spray away from peripheral roughs. But in a region where winds can vary despite prevailing from the west, drift from the sprinklers is inevitable. And when the areas near to fairways and shorter roughs get wet like that, they pose the danger of a lost ball for a golf shot that is only marginally offline.
