This will be the first time they have met.
No one expected Konjuh to be in the quarter finals. She has played some strong tennis to get here and beat Radwanska in straight sets in the 4th round. She was broken just once in that match. Her opening match against Bertens saw her struggle to find her timing on serve but she has improved it since then.
Pliskova has a poor record in grand slams. I had expected Venus Williams to beat her in the last round and their match went to a 3rd set tie break. Only Venus has been able to put her under pressure and Pliskova faced 16 break points in that match and was broken 6 times.
Pliskova starts around 1.45. I think there is a very good chance that we see a higher price on her. She is favourite and that brings extra pressure to a player who has never been this far in a slam.
Back Pliskova if she gets broken first.
