The American golfer Phil Mickelson has steadfastly refused to be drawn into the Steve Williams race row on despite previously being abused by the controversial caddie.
Mickelson, who was once described as "right prick" by Tiger Woods's former caddie and ridiculed about his weight, first tried to dodge the question and then flatly refused to answer.
Mickelson was on the receiving end of insults from Williams in 2008 when the caddie launched into a diatribe against the then world number three at an event in New Zealand.
Williams, who's now working with Australian Adam Scott, enraged the golf world last week when he made a racial comment against Woods at a function in Shanghai last week.
Mickleson's now slipped outside the top ten, sitting eleventh on the world rankings.
