After winning her eighth title in Key Biscayne on Saturday, Serena Williams goes into the claycourt season with whispers of a calendar Grand Slam on the lips of many spectators.
Despite being 33 years of age, Williams is playing as well as ever and according to the world number one, she has a far better understanding of her game and uses her array of shots and power to much better effect than in the past.
"I actually think that I read the game better," Williams said after her straight sets romp over Carla Suarez Navarro in Miami on Saturday.
"Like when I'm playing an opponent, after three games I'm like, 'OK, now I know what you're going to do … or when the coach comes out I really key in on what they change their games to.
"I don't think I did that before. I think that's just experience and age."
The world number one has a perfect record so far this year – 18 wins from 18 matches – including a victory at the Australian Open to claim her 19th Grand Slam title.
That victory in Melbourne means Williams is now the holder of all four Grand Slam titles, having won the French Open, Wimbledon and the US Open in 2014.
The calendar Grand Slam, however, has only ever been managed by three women – Maureen Connolly Brinker in 1953, Margaret Court in 1970 and Steffi Graf in 1988.
"Obviously, anyone that wins the Australian Open wants to win a Grand Slam," she added.
"I’ve won the Australian Open six times, and I have not done that yet. I’m not saying this is the year or not the year. Who knows?"
In fact, Williams has never been able to win the Australian and French Opens in the same year, and the last player who managed that feat was Jennifer Capriati in 2001.
"I just think that sometimes the tournament's hard or you just fall and you fall at the wrong time," Williams said.
"That's just what happens.
"I think in clay courts obviously you have longer matches, consistently have longer matches, so I've got to be ready for that. I'm ready for it."
