Less than halfway through 2018, and it's already looking like a banner year for Petra Kvitova as the Czech notched up her fourth title of the season at the Mutua Madrid Open for a Tour-leading haul of championships.
It was the third time Kvitova had raised the trophy in the Spanish capital after victories in 2011 and 2015, and following her win at home in Prague the previous week, marked the second time in 2018 that the 26-year-old had won consecutive titles. Her current winning streak of 11 is her second of the year after her February/March run through St. Petersburg, the first round of Fed Cup and Doha.
Consequently, Kvitova is now hot on the heels of Porsche Race to Singapore leader Caroline Wozniacki, bouncing up two places to land at No.2 - and only 38 points behind the Australian Open champion.
Madrid runner-up Kiki Bertens also continues her clay-court charge, zooming up eight places to land at No.11. Having languished down at No.68 before the clay season, her 11-2 record on the terre battue so far this year has rocketed the Dutch player into contention for the BNP Paribas WTA Finals Singapore presented by SC Global.
Semifinalists Karolina Pliskova and Caroline Garcia also enjoy a boost. The Frenchwoman, who made the last four for a second straight tournament, rises two to No.12, while Stüttgart champion Pliskova solidifies her position in the top eight of the Race by moving three places up to the joint No.4 position, which she shares with Angelique Kerber.
Madrid quarterfinalist Daria Kasatkina also continues her incursion into the higher echelons of the Race. The 21-year-old Russian rises one place to overtake Naomi Osaka - and take the Indian Wells champion's position as the youngest player in the Top 8.
Further down, a third-round showing enables Kristina Mladenovic to climb nine spots to No.29; Bernarda Pera's breakthrough season keeps bringing more highlights for the American, who defeated Johanna Konta for the second time this year in the second round of Madrid and who rises 27 places to No.41; and Maria Sharapova, who reached her first quarterfinal above International level in over a year, zooms up 49 rungs to land at No.50.
