A random fan turned to the great Roger Federer to solve the dilemma whether tennis balls are green or yellow. "Hey Roger, are tennis balls green or yellow," a curious random fan shouted to Federer. The 20-time Grand Slam champion turned to the fan with a smile on his face and replied: "Yellow, right?" The fan then proceeded to add that he thinks tennis balls are green, while his son thinks they are yellow.
Meanwhile, Federer is preparing to kick off his Miami Masters campaign.
Top seed and defending champion Federer has a round-one bye. The 36-year-old will be meeting a qualifier in round two. Federer, who debuted at Miami long ago in 2001, has made it all the way at Miami three times so far in his career.
Federer ended runner-up to Argentine Juan Martin del Potro in last week's Indian Wells Masters final. The Swiss paid the price for blowing three match points in the final. Also read: Bernard Tomic ready to prove doubters wrong, make them eat their words .
