The tension was palpable, and the fans hushed when DeChambeau moved toward his golf bag.As DeChambeau explained later, if he ultimately pulled an iron from the bag, the response was a crestfallen bellowing, as if the crowd had seen a child’s just-bought ice cream cone fall and splatter on the ground.“It’s always like a big ‘Awwww’ for an iron,” DeChambeau said after his round on Friday.And if he tugged his mammoth driver from the bag? Think climatic movie scene in which a hero finally vanquishes the villain.“If it’s the driver, it’s like, ‘Yeah!’ ” DeChambeau said with a hearty grin.It has come to this on the PGA Tour, and perhaps it is not a surprise.
