US Senior Open 36-hole co-leader Padraig Harrington was not happy with one of NBC's course reporters for breaching what he called "golf etiquette."

It was for Padraig Harrington a week that began with double-doubles (burgers, not bogeys), a lost ball and losing a specious debate. It ended with a declaration of profound gratitude and another U.S.

The wisp drifted in from the same spot it has all week, a hint of grey poking its head over the ridges of The Horns before hovering angry over the back greens of The Broadmoor.
