#4 Victoria Azarenka
Belarus' 30-year-old tennis star, Victoria Azarenka was at her peak in the 2012-13 season. She won the Australian Open in 2012 and 2013 while she finished runner-up to Serena Williams at the 2012 and 2013 US Open. She did not achieve much success on grass and clay courts but she was very dominant on the hard courts. Her clinical performances helped her achieve the number 1 position in WTA rankings in January 2012. She stayed at the helm for 19 weeks but lost the spot to Maria Sharapova in June 2012. Azarenka currently holds the 18th rank in doubles rankings.
#3 Simona Halep
Romania's world number 4 player, Simona Halep had achieved the pole position in WTA rankings before she won her first Grand Slam title. She lost that rank to Caroline Wozniacki soon however, she regained her crown after winning her first major at Paris in 2018. Halep held the numero uno spot for 48 weeks. She did not qualify for the final of any Grand Slam tournament until the 2019 Wimbledon where she crushed Serena Williams in straight sets. The 28-year-old will look to add more trophies to her cabinet besides taking back the number 1 spot of WTA rankings in the next decade.Published 30 Dec 2019, 18:36 IST
