Zach Johnson and Billy Horschel exchanged angry words with spectators as tempers frayed on the final day of the WM Phoenix Open.<\/p>\n

Johnson was filmed remonstrating with fans at TPC Scottsdale and could be heard telling them \u201cI\u2019m sick of it\u201d before demanding they \u201cjust shut up\u201d.<\/p>\n

It was not apparent from the clip, which was posted on social media, what prompted the former US Ryder Cup captain to lose his temper.<\/p>\n

In a separate incident, Horschel was seen remonstrating with a spectator for calling out while one of his playing partners, qualifier Nicolo Galletti, was about to hit a shot.<\/p>\n

\u201cBuddy, when he\u2019s over a shot shut the hell up man,\u201d Horschel shouted.<\/p>\n

\u201cHe\u2019s trying to hit a damn golf shot here \u2013 it\u2019s our f****** job.\u201d<\/p>\n

The WM Phoenix Open is easily the best attended tournament in golf, but the behaviour of some fans has again attracted more attention than the golf itself.<\/p>\n

One man was arrested after jumping over the ropes and diving into a greenside bunker on the par-three 16th, where he proceeded to perform \u2018snow angels\u2019 in the sand.<\/p>\n
