It doesn't happen in other popular sports like football, cricket or basketball, but women are certainly matching men when it comes to making the millions in tennis.
According to Wealth X, the ultra high net worth (UHNW) intelligence firm, and as mentioned in this Times of India report, five women figure in the top-10 list of richest tennis players. In fact, there are three women in the top five!
The list is topped by Roger Federer, whose grand-slam laden career has seen him build up a net worth of $180 million. Rafael Nadal is at No 2 with $120 million.
And not far behind is Russian Maria Sharapova with $95 million. Despite recent failings in tennis tournaments, Sharapova's brand value doesn't seem to be waning. She has also started her own line of sweets/candies called 'Sugarpova'.
The Williams sisters occupy the fourth and fifth spots. While Serena has amassed $90 million, sister Venus is worth $60 million.
And Novak Djokovic maybe the world No 1 when it comes to the tennis court, but lies sixth in the list with $55 million.
Andy Murray, giddy with his latest Wimbledon success is at seventh, valued at $42 million. He is followed by Chinese Li Na ($35 million), veteran Aussie Lleyton Hewitt and former women's world No. 1 Caroline Wozniacki. Hewitt and Wozniacki have both got a net worth of $30 million each.
Murray however, doesn't have much to worry about. Wealth X predicts that his net worth will rise to $160 million by 2018.
Keeping with the average age of retirement in tennis, which is at 30-years old, players like Roger Federer, Serena and Venus are likely to retire by 2018 (when they will be 36, 35 and 38 years old respectively). Nadal, although comparatively younger, has an uncertain future due to his serious injuries. This leaves a lot of green pastures for Murray.
The report quotes Wealth X CEO Mykolas D Rambus as saying: "If he keeps his winning trajectory, we estimate the value of Brand Murray to rise significantly. As older players retire, Murray has a strong chance of rising up our rank of the world's wealthiest tennis players."
