For the second time in Sloane Stephens' career, the American takes home a title on home soil, this time at the Volvo Car Open (the only tournament played on green clay) in Charleston, South Carolina. It is Stephens' fourth career title overall and her third of 2016. Across the Atlantic in Europe, Dominika Cibulkova raced to the Katowice Open title. It is the Slovak's first title in more than two years.

Sloane Stephens had not made a WTA final let alone win a title till she broke the duck at the Citi Open on home soil at Washington D.C. last July. Entering 2016, she has since won titles in Auckland and Acapulco bringing her total tally to three and now the biggest title of her career at the Premier-level Volvo Car Open.

Besides maintaining her 4-0 record in finals, she became the first player to win multiple titles this year and now the first player to lift trophies on different surfaces. Moreover, an interesting statistic worth noting is that Stephens has been 'go big or go bust' this year. Other than her three title runs, she exited in the opening round of her other tournaments. 

Finalist Elena Vesnina was the fairytale topic of this year's edition coming through qualifying and eventually made it to the championship match before falling to an inspired Stephens 7-6(4), 6-2. In other news, defending champion Angelique Kerber had to retire in her semifinal match due to a virus.

Only three of the top eight seeds managed to survive past the round of 16 as second seed Belinda Bencic, fourth seed Lucie Safarova, sixth seed Andrea Petkovic and eighth seed Madison Keys all lost their opening matches. Third seed Venus Williams was stunned by Yulia Putintseva in the round of 16.

This year's edition of the Katowice Open saw its eighth seed Dominika Cibulkova blitz past fifth seed and two-time (2014 and 2015) finalist Camila Giorgi in straight sets.  It is the Slovak's first trophy since winning the Abierto Mexicano Telcel more than two years ago and her fifth overall. Moreover, this marks Cibulkova's first trophy in an indoor tournament since winning her first title at the Kremlin Cup in 2011.

It has been a tough road for Cibulkova since coming back from an Achilles surgery middle of last year which kept her out for three months and this title will mean a lot to her. On Giorgi's part, this will be another heartbreaking loss for the Italian who could not make it third time lucky here, having finished second best in 2014 (to Alizé Cornet) and 2015 (to Anna Karolina Schmiedlova).

Katowice lost its top seed and defending champion in a slumping Schmiedlova in the opening round to eventual semifinalist Pauline Parmentier. Other than that, third seed Jelena Ostapenko, seventh seed Timea Babos and ninth seed Kirsten Flipkens all had good runs in the tournament, the former reaching the last four and the latter two posting quarterfinal results.
