The World No.1 surged to the top of the leaderboard after an outstanding serving performance at the Miami Open, where she led the tournament with 43 aces over six matches.

Holding serve on the WTA Tour is a premium advantage and Barty and Osaka lead the tour in Service Games Won by a fair margin, which should come as no surprise for the two players with the highest winning percentages on tour this season.
Is Sara Sorribes Tormo the toughest out in the game right now? Well you certainly don't want to see her when you're serving. The Spaniard has surged up to a career-high No.48 after an outstanding month of March, where she won her first WTA title in Guadalajara, made the semifinals in Monterrey, and made her first WTA 1000 quarterfinal at the Miami Open. Sorribes Tormo is winning half of her return points and breaking serve nearly every two return games.
Switzerland's Viktorija Golubic also features prominently in the return statistics. Armed with one of the rare one-handed backhands on tour, Golubic made back-to-back finals in Lyon and Monterrey.
Interestingly, only Petra Kvitova features in the Top 10 of both Service Games Won and Return Games Won.
