Safe to say McIlroy wasn't happy about losing it.
After a battle that featured several rounds of full-throated screaming, fist-pumping and finger-wagging, McIlroy said that he had no hard feelings toward Reed. The players did indeed appear to be enjoying themselves throughout the round, even as they taunted each other to rile up the crowds.
But McIlroy did let off a little steam in the immediate aftermath on the 18th green. Moments after shaking hands with Reed, a small 360FLY camera planted on the collar of the green by PGA.com captured McIlroy tossing his putter in frustration, then conferring for a few moments with captain Darren Clarke and assistant captain Ian Poulter.
Moments later, McIlroy appears to spot the camera, which was mounted on a 12-inch tripod, and kicks it over.
