Caddie extraordinaire Steve Williams believes the modern golfer needs to lighten up.
"It's a serious business but they need to stop taking themselves so seriously," said the big Kiwi, who became the game's highest profile caddie while working for Tiger Woods.
Williams has confirmed the details of a controversial conversation he had with Korean-American golfer Kevin Na, during a 2014 tournament in Germany. Na revealed in a Sports Illustrated profile last week he got upset with Williams, who told Na he was like a bad movie.
However, Williams stressed to the Herald how slow Na was playing.
Williams, who was working for Aussie Adam Scott, said the group including Na - who is notorious as golf's slowest player - was put on the clock twice, upsetting the rhythm of his playing partners.
