WTA Rising Star Karolina Pliskova was the first to book her place in the semi-finals of the BNP Paribas Fortis Diamond Games and will meet Carla Suarez Navarro on Saturday.
Pliskova won the battle of the Czechs when she levelled her head to head against fellow countrywoman Lucie Safarova in straight sets for a 7-6(5) 6-3.
Speaking after the match, Pliskova said: "It's definitely tough to play against another Czech player. It's always difficult to play someone from your country, and all of the girls in the Top 100 are really great players too.
"I felt that whoever won the first set today would win the second set. I think she was actually better in the first set - she had more break points and served better than me. But in the end of the first set I played two good games, and I think that made the difference, especially in the second set."

She will face Suarez Navarro who outran an in-form Francesca Schiavone who had battled through qualifying and almost had the Spaniard on the ropes as she sped out to a 3-0 lead before Suarez Navarro ran off 12 of the next 14 games to turn the tables on the former French Open champion, and after having won her first career title last year, she finds herself in her first Premier semi-final.
"Francesca played really, really aggressive in the beginning," she said. "It's always a difficult match for me when I play against her, and early in the match it looked like another one.
"After being down I'm really happy I was able to win this match in two sets."
Pliskova already has a win over Suarez Navarro this year, having beaten her on the way to the Sydney final as they met in the last eight.
"She's playing amazing this year," Suarez Navarro said. "She serves really well, so I need to be very focused on my returns all the time. I just need to fight every point to beat her."
Pliskova does possess a potent serve and plays a strong attacking game, but could be vulnerable if Suarez Navarro can bring a lot of variety to her game on Saturday.
Pliskova and Suarez Navarro are scheduled on Centre Court, not before 3pm (2pm GMT).
