The WTA's finest battled it out at 61 tournaments, 33 countries and six continents this year, culminating in the 2016 Year-End WTA Rankings, which are official today, Monday, November 7.

Here are 10 Things To Know about this year's year-end list...

1) Kerber is year-end No.1 for the first time.
After a season that saw her lift two Grand Slams, Angelique Kerber finishes with the much-deserved year-end No.1 ranking. Read more about her feat here.

2) Serena's reign ended.
Her loss to Karolina Pliskova in the US Open semifinals ended Serena Williams' 186-week stay at the top of the rankings. However, despite playing only eight events, the American enjoyed plenty of highlights in 2016, defeating Kerber at Wimbledon to lift her 22nd major and reaching the final at both the Australian Open and Roland Garros

3) Radwanska holds steady at No.3.
Another season of remarkable consistency brought Agnieszka Radwanska three titles and a sixth consecutive finish inside the Top 10.

4) Strong second half gives hope for Halep.
Following a slow start, Simona Halep's season really caught alight in the summer, a string of deep runs on the cement paving her path to another year-end Top 5 ranking.

5) Singapore success fuels Cibulkova's rise.
Dominika Cibulkova's 2016 resurgence featured many memorable moments. None, though, could come close to topping her brilliant victory over Kerber at BNP Paribas WTA Finals Singapore presented by SC Global. The performance was rewarded with the biggest title and highest ranking (No.5) of her career.

6) Pliskova finally makes her breakthrough.
Karolina Pliskova ended her Grand Slam hoodoo in stunning fashion at the US Open, upsetting Serena before losing out to Kerber in an entertaining final. The result saw her rise to No.6, where she also finished the year. 

7) Muguruza slips despite maiden major.
While there were signs of a revival in Singapore, Garbiñe Muguruza failed to build on June's Roland Garros breakthrough, a second half of the season slump seeing her slip to No.7.

8) Fresh and familiar faces join Top 10 party.
Madison Keys continued to make good on her boundless potential, ending a season of steady progress at No.8. Also joining her was Johanna Konta, who became the first Briton since 1983 to end the year inside the Top 10. Sandwiched between the newcomers was a familiar face, as Svetlana Kuznetsova ended the campaign inside the Top 10 for the sixth time.

9) And there could be more next year.
Petra Kvitova finished the year like a steam train, rising to No.11 following titles in Wuhan and Zhuhai. A Top 10 return will surely soon follow, while the next generation is also well represented in the upper echelons, Elina Svitolina (No.14), Caroline Garcia (No.23), Daria Gavrilova (No.25), Timea Babos (No.26), Daria Kasatkina (No.27) and Monica Puig (No.32) all achieved the best year-end ranking of their fledgling careers.

10) A little more about the year-end Top 100...
The oldest and youngest players in the year-end Top 100 are Venus Williams (36) and Catherine Bellis (17), and there are 32 countries represented in there (the United States has the most players with 16).
