Take away the massive build-out already in place for the 45th Ryder Cup to be played in late September, and Monday was an otherwise routine day at Bethpage State Park.

The driving range was bustling, with every hitting bay occupied by players displaying all fashions — from fancy, name-brand golf attire and gaudy belts to those in cargo shorts, untucked shirts and tattoos covering their arms and legs.

By around 1 p.m. around the Red Course, though, the energy changed.

Keegan Bradley, the U.S. Ryder Cup captain and an adopted New Yorker as a former player on the St. John’s golf team, which played college matches on the Red, was cruising around the course with his wife, Jillian, sitting alongside him in his red captain’s golf cart, both sipping transfusion cocktails.
