2016 WTA Player Of The Year Finalists

Angelique Kerber: Winner of two major titles in 2016, Kerber leads the WTA for most main draw match wins this year (57-16) and most main draw match wins on hardcourt (39-10). Her first Grand Slam breakthrough came in January, with a three-set win over Serena Williams in the Australian Open final. As the tour transitioned to clay, Kerber won the Porsche Tennis Grand Prix, defending a title for the first time in her career in front of her home crowd. A strong summer swing that saw her reach the finals at Wimbledon, the Olympic tennis event and Western & Southern Open propelled her to a second Grand Slam title at the US Open, where she also became the first German to ascend to No.1 since Stefanie Graf. Kerber qualified for her fourth BNP Paribas WTA Finals Singapore presented by SC Global appearance in the last five years. Looking to clinch the Year-End No.1, she leads the WTA for most Top 10 wins for the 2016 season (8-3).

Serena Williams: The American’s 2016 season is defined by her 22nd Grand Slam title at Wimbledon. Serena now sits equal with Steffi Graf on the Open Era leaderboard for most major titles, behind only Margaret Court with 24 all time. She also won her sixth major doubles title at the All England Club alongside sister Venus. Like Kerber, Serena reached three Grand Slam finals this year, finishing runner-up at the Australian Open and French Open, and winning the Internazionali BNL d’Italia in between. She qualified for the upcoming 2016 WTA Finals Singapore – her 10th appearance at the year-end finale. Before ceding the No.1 ranking to Kerber, Serena tied Graf for most consecutive weeks atop the WTA rankings at 186 weeks.

Garbiñe Muguruza: Muguruza enjoyed a major breakthrough of her own at Roland Garros, where she knocked out then-World No.1 Serena Williams title at Roland Garros, defeating the then-No. 1 Serena Williams in the final. At 22 years, seven months old, Muguruza became the youngest Grand Slam champion since Victoria Azarenka in 2012. She also reached the semifinals at the Internazionali BNL d’Italia and the Western & Southern Open. Her win at Roland Garros brought her to a career-high ranking of No.2 on June 6, 2016.

Simona Halep: The Romanian is one of the four players to have won three singles titles in 2016, including at Madrid, Bucharest, and Montréal – owning a 3-0 record in finals this season. She qualified for a third straight appearance at the BNP Paribas WTA Finals Singapore presented by SC Global, and became the third woman to clinch a berth after reaching the semifinals at the Dongfeng Motor Wuhan Open. Halep also reached the last four in Sydney and Cincinnati. Since becoming the third Romanian woman to ever break into the Top 10, she has become the highest-ranked Romanian ever, peaking at World No.2.

Karolina Pliskova: Pliskova thundered into to her first Grand Slam final at the 2016 US Open, making her the first Czech to reach the final since Helena Sukova in 1993. Coming in having defeated future-No.1 Angelique Kerber in the final of the Western & Southern Open (winning her second title of the season after Nottingham), she became the eighth player to beat both Williams sisters to reach the championship match in Flishing, where she lost to Kerber in three sets. She qualified for the WTA Finals in both singles and doubles, and will make her first appearance in Singapore. Pliskova currently sits as the No. 1 Czech player; she claimed the title for the first time in mid-August, overtaking Petra Kvitova, who had held the distinction since 2011
