Serena: The greatest win of my career

Serena Williams has claimed 23 grand slams during an illustrious career but the American superstar ranked Tuesday's Australian Open first-round rout of Tatjana Maria as the "greatest win of my career".

Former world number one and this year's 16th seed Williams flexed her muscles in a 6-0 6-2 demolition of German Maria at Melbourne Park.

Williams was back in Melbourne for the first time since winning the 2017 Australian Open - the 37-year-old skipping last year's event following the birth of her daughter.

And veteran Williams, who is seeking an eighth Australian Open title, revelled in the result afterwards.

Williams unveiled a new eye-catching green bodysuit in Melbourne, where she was also wearing compression stockings.

Asked if she was still worried about the thrombosis issue revealed in 2011, Williams said: "Definitely still concerned. I have had some issues, and they're not done. So, it's just something I just have to do for pretty much probably the rest of my career, we'll see. But I'm always at the doctor.

"With DVTs, it's very scary. I know a lot of people – they're very common. A lot of people have them. Especially for me it's incredibly frightening. I lay on the side of precaution as opposed to not."
