Pliskova vs Muguruza. Western & southern open 2016

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 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 kuznetsova
