June 2016 WTA Breakthrough Performance of the Month Finalists:

Elena Vesnina: The Russian veteran has enjoyed regular success at the upper echelons of the doubles circuit, but finally broke though in a big way at a singles Slam, reaching her first semifinal at Wimbledon with wins over Ekaterina Makarova and Dominika Cibulkova. Ranked outside the Top 100 to start the season, Vesnina has cut her ranking by nearly 100 spots since her February low of No.122 and is back inside the Top 25 for the first time since January of 2014.

Madison Keys: Keys not only earned her second title on grass at the Aegon Classic, but she also made a major rankings breakthough by becoming the first American to debut inside the Top 10 since Serena Williams in 1999. Keys backed up her newly minted Top 10 ranking with a run to the second week of Wimbledon, her sixth trip to the round of 16 or better at a major in her last seven outings.

Anastasija Sevastova: Briefly retired for a space of 18 months, the Latvian is arguably playing better than ever as she continues her climb back up the rankings, making a breakthrough at the Mallorca Open, where she reached the final – her first since 2010. The run also brought Sevastova back into the Top 70.
