Sloane Stephens beat Elena Vesnina in the 2016 Volvo Car Open final last April, and both were officially added to the 2017 field Monday. Stephens, 23, joins Venus Williams and Caroline Wozniacki as past champions who will play in the tournament scheduled for April 1-9 on Daniel Island.
Stephens is No. 35 in the current Women’s Tennis Association rankings. Vesnina is No. 16.
Also added Monday: Johanna Konta of the United Kingdom, ranked No. 10.
“Our player commitments continue to grow, and we are thrilled to bring Johanna, Sloane and Elena to Charleston,” tournament manager Eleanor Adams said.
Konta, 25, is having a breakthrough year and will play in the tournament main draw for the first time. She won her first WTA title this year in Stanford. She made the finals in Beijing and semifinals in Eastbourne and at the Australian Open. Konta also reached the quarterfinals in Wuhan, Montreal, Miami, Monterrey and the Rio Olympics.
She is the first woman from Britain to reach the top 10 in 32 years.
Stephens has three WTA titles in 2016, with Auckland and Acapulco along with the Volvo Car Open. With a winner’s check of $128,100 last April, she received a new car, a blue Volvo V60 Polestar.
Vesnina has played in 10 previous Charleston tournaments. She was also a singles finalist in 2011. Along with fellow Russian Ekaterina Makarova, she won a Gold Medal in the 2016 Rio Olympics in women’s doubles.
