It’s been an historic 2015 season for Serena Williams, highlighted by another three Grand Slam titles at the Australian Open, French Open and Wimbledon, bringing her career haul to an impressive 21.

It’s the third-most all-time, male or female, after Margaret Court’s 24 and Steffi Graf’s 22.

And as we keep moving through the off-season, Williams keeps piling on the accolades – not only did she secure the WTA Year-End World No.1 Singles Ranking presented by Dubai Duty Free for the fifth time, and not only was she voted WTA Player Of The Year for the seventh time, but this week she became the first woman this millennium to be named Sports Illustrated Sportsperson Of The Year.

“This year was spectacular for me,” she Instagrammed Monday. “For Sports Illustrated to recognize my hard work, my dedication, and my sheer determination gives me hope to continue on and do better. As I always say, it takes a village – it’s not just one person. This is not just an accomplishment for me, but for my whole team. I am beyond honored. I love you guys! 2016? #letsdoit.”

And once the WTA stars hit the tennis courts in the Asia-Pacific again in a few weeks, Williams will have her eyes back on the biggest prizes – the Grand Slams, beginning with the Australian Open.
