For 15 years now Serena Williams has been in control of women's tennis and following her Sony Open win last week, she is showing no signs of stopping.
With 17 Grand Slam singles titles to her name, you would be forgiven for thinking Williams may soon call time on her career having already achieved so much.
After all, she is the same age as Roger Federer who it has been argued is slowing down in his career, with his recent quarter-final loss to Kei Nishikori of Japan at the Sony Open in Miami, adding to the speculation.
For Williams though the victories just keep on coming and she ended 2013 with a staggering 34-match winning streak. This is as well as winning a number of Grand Slam women's doubles championship titles with her sister Venus who despite achieving the Dubai Championships title last month, has been plagued with injury in recent years.
To explain Williams' dominance, we only need to look at the win-lose ratios she has over any of her opponents. Arguably the second biggest name in women's tennis, Maria Sharapova has not beaten Williams for ten years with runner-up in Miami Li Na, falling victim to Williams ten times in 11 encounters.
Perhaps the difference between those at the top of the women's and the men's game is the lack of a real opponent for Williams. The elite in men's tennis comprise of Federer, Rafael Nadal, Novak Djokovic and Andy Murray, with several others worthy of note inside the top ten.
For Williams though no one is close to hindering her supremacy and a lack of no main opponent only makes it easier for her career earnings to add up further and her number of titles to extend.
Though not perfect; she lacks a sense of fluidity, but everything else she seems to master. A powerhouse made for the sport, for as long as Serena Williams continues to play tennis, she will continue to dominate the women's half of it.
