Angelique Kerber

Angelique Kerber ([ʔandʒɛˈliːk ˈkɛɐ̯bɐ]; born 18 January 1988) is a German professional tennis player. A former world No. 1 and winner of three Grand Slam tournaments, she made her professional debut in 2003 and rose to prominence upon reaching the semifinals of the 2011 US Open as the No. 92-ranked player in the world. She ascended to the top of the rankings on 12 September 2016, thus becoming the twenty-second and oldest player to achieve the number-one ranking for the first time.

A continually high-ranking left-handed female tennis player, Kerber has won 12 career singles titles across all surfaces on the WTA Tour, including the aforementioned three Grand Slam titles: the 2016 Australian Open, the 2016 US Open and the 2018 Wimbledon Championships.

At the BNP Paribas Open, Kerber lost her opening round to Denisa Allertová, giving Radwanska the opportunity to surpass her for the No. 2 spot by reaching the semifinals. However, this lasted a week before Kerber was able to reclaim her ranking in Miami by advancing to the semifinals.

Her next event was the Volvo Car Open, where she was the top seed and defending champion. She reached the semifinals to face Sloane Stephens and she was forced to retire due to a viral illness.

She defeated Plíšková in three sets in the final to claim her second Grand Slam title.

In Wuhan, in her first tournament since claiming the world No. 1 ranking, Kerber defeated Kristina Mladenovic before losing to Petra Kvitová in 3 hours and 19 minutes.

On 17 October 2016, Serena Williams pulled out of the WTA Finals in Singapore due to a shoulder injury. This withdrawal secured Kerber's spot at the summit of the WTA rankings for the rest of the year. This was Kerber's first time ending the year with the No. 1 ranking. As the top seed of the Tour Finals, Kerber was drawn in the red group alongside Simona Halep, Madison Keys, and Dominika Cibulková.

At the latter, Kerber also received a first-round bye and defeated Mona Barthel to set up a rematch of her Olympic final against Monica Puig, which she won in straight sets.

In Monterrey she reached the final.

Kerber began the clay court season with a loss in Stuttgart to eventual runner-up Kristina Mladenovic which dropped her from the top slot. Then she retired in the third match of Madrid, but due to Serena's absence became world No. 1 again. At the French Open, Kerber became the first WTA No. 1 in history to be ousted in the first round of the French Open, falling in straight sets to Ekaterina Makarova.

At the start of Kerber's grass court season, she reached the quarterfinals of the Eastbourne International, before being defeated by home favourite Johanna Konta. Kerber went out in the fourth round of Wimbledon, losing to eventual champion Garbiñe Muguruza.

Kerber is a defensive baseliner, who has been noted for her speed, agility, athleticism, and footwork.

Her forehand is widely considered her most dangerous weapon, with her being able to hit powerful shots with disguise and speed. Kerber is known for hitting her backhand whilst squatting, allowing her to generate considerable power and to create sharp angles on the court. Her serve is considered her major weakness, rarely serving aces and hitting, on average, fewer service winners than many of her fellow players.
