CINCINNATI, OH, USA – Angelique Kerber is gunning for the No.1 ranking in Cincinnati, but the German isn’t the only one with designs on the Western and Southern Open title. Chris Oddo previews Saturday’s semifinals right here at wtatennis.com.

Saturday, Semifinals

Center Court
[4] Garbiñe Muguruza (ESP #3) vs. [15] Karolina Pliskova (CZE #17)
Head-to-head: Pliskova leads, 2-1

Key Stat: Pliskova leads all players in the ace category in 2016 with 394 through her first three rounds in Cincinnati.
Karolina Pliskova had the upper hand on Garbiñe Muguruza when they met head-to-head in 2015, defeating her in Dubai and then again a month later at Indian Wells, but it is Muguruza who has proven to be more comfortable on the big stage since the pair last met. The Spaniard is a Grand Slam winner and a Top 5 player now, while Pliskova has still to reach the second week of a major. But don’t be fooled by the Czech’s lack of Slam success. The 24-year-old is progressing steadily and it’s just a matter of time before she has her day in the sun. Will it be Saturday? Pliskova will need to serve effectively to win for the third consecutive time against Muguruza, and she knows she’ll have to make more first serves than she did on Friday in her quarterfinal win over Svetlana Kuznetsova. She only managed a 44% first-serve percentage in her three-set win over the Russian, but was pleased to earn her second Top 10 win of the year nonetheless. “I can serve big in the important moments which is good, but I have to get high with the percentage,” Pliskova said. “Still happy with the serve. I think it’s still winning the matches for me, so still the biggest weapon.” Speaking of weapons, the powerful Muguruza is not lacking in that department. She knows she’ll have to use her full arsenal to change her fortunes against the dangerous Pliskova. “She’s playing well,” Muguruza said on Friday after defeating Timea Babos in the quarterfinals. “I think this surface helps her a little bit with her style of game.” Muguruza has been focused and in the zone all week, and it has shown on the scoreboard. She’ll take a confident air with her on the court and let the chips fall where they may. “I’m satisfied the way I’m fighting and my spirit and energy on the court, so hopefully I can keep this until the US Open,” she said.

Pick: Muguruza in two

[2] Angelique Kerber (GER #2) vs. [3] Simona Halep (ROU #4)
Head-to-head: Halep leads, 4-2

Key Stat: Kerber could ascend to the No. 1 ranking for the first time with the title in Cincinnati.
Two steps from a career-changing milestone, Angelique Kerber continues to wear the blinders and deflect all pressure about climbing to the top of the WTA rankings. “I’m not feeling more pressure, to be honest,” she said after coming back from a set down to defeat Carla Suárez Navarro in the sweltering Cincinnati heat on Friday. “I learned a lot from last tournaments and last matches about pressure, and when I put the pressure too much on myself, I mean, that’s not the way I would like to play my tennis.” Though Kerber struggled early against the Spaniard, she drew upon a reservoir of confidence and found her second wind to win on Friday. It’s been a recurring theme for the German, and as the wins pile up, the confidence grows. “I knew I’m really fit and I worked a lot in the last few months and years to go out and try to play matches like that,” she said. “Of course when you win the matches you have much more confidence and you can do it and turn around matches and go for three sets after you lose the first one. That gives me for sure more confidence also for the next challenges.” The challenge will be a big one on Saturday, as Kerber will square off with the scorching-hot Simona Halep. The Romanian notched her 13th consecutive win on Friday night, taking down Agnieszka Radwanska in straight sets, and she is playing her best tennis of the season at the moment. Like Kerber, Halep fell behind early but stormed to the finish, taking 13 of the final 15 games from Radwanska. Will Halep be able to continue her run and rain on Kerber’s parade in Cincinnati, or will the German edge ever closer to a colossal milestone?

Pick: Halep in three

By the numbers…
1 – Number of singles semifinalists still alive in the doubles draw (Pliskova and partner Julia Goerges face Martina Hingis and CoCo Vandeweghe).
20-2 – Halep’s record since the start of Roland Garros this year.
46 – Kerber’s 2016 win total – more than any other player on tour.
183 – Number of consecutive weeks that Serena Williams has held the No. 1 ranking, which is second-most all time behind Graf (186).
