WIMBLEDON – With the help of the Centre Court roof, all four women’s quarterfinals were completed Tuesday.
One was played outdoors on No. 1 Court. Two were played under the roof on Centre Court (one ending with the scream of an overeager British fan).
And the last one began on No. 1 Court, and was completed three hours later under the roof.
The two women’s singles semi-finals, to be played Thursday, are set.
No. 6 Johanna Konta of Great Britain is the highest seed remaining. She will play No. 10 Venus Williams.
The other semifinal will feature 2015 finalist Garbiñe Muguruza, seeded No. 14 against the fairy tale of this fortnight, Slovakia’s unseeded Magdalena Rybarikova.
Here is what they said.
 Johanna Konta (GBR) def.  Simona Halep (ROU) 67 (2) 76 (5) 64
Konta: “I guess to be in the semifinals of my home Slam, and to do that in front of a full Centre Court, I mean, it’s pretty, pretty special. I think the level of tennis that both of us played today, it was just a tremendous match. … I feel very happy with how I was able to maintain my level throughout the whole match, and really just tried to stick very closely to how I felt I wanted to play out there, and did that kind of through the thick and thin.”
Halep: “I think was a great tennis. Both of us played a good level. I was very close, again. In the tiebreak maybe I could serve better and stronger a little bit. Then in the third set, the serve game that I lost was a little bit tough to still believe that I can break her because she was serving pretty well. … I think everything was okay. Many positives from this match. And she played really well, so she deserves to win.”
 Venus Williams (USA) def.  Jelena Ostapenko (LAT)
Williams: “I know she had to be feeling confident. She played a great match. Not a lot of errors. I never played her. Watched her. Didn’t really know what to expect. The grass, of course, changes the game. So just a lot of factors. I was really happy to come out on top. … ”
Ostapenko: “She was playing good today. She was serving well. I think I didn’t start the match very well. I was missing a little bit. But, yeah, she was serving really well. It was very tough to break. Because of that I had more pressure because I had to keep my serve. … It was also a good match today for me. … I had kind of, like, some pressure because, as I said, she was serving really well today. She started the match good. She made a lot of aces. But, yeah, I was not, like, feeling nervous. I just couldn’t really play my best today.”
 Garbiñe Muguruza (ESP) def.  Svetlana Kuznetsova (RUS) 63 64
Muguruza: “I’m very happy and very pleased also with this match, because obviously Kuznetsova is a very tough opponent. We all know she has been and is a great player. I managed to play a good level during all the match. I earned the victory. … Before I was more emotional. You know, I was showing more emotions on the court. Now I’m trying to handle it better. I think that’s experience. Like I said before, the year I made final here, I felt like I was a completely different player. Now I maybe feel more solid mentally, going out there knowing what to do. I think it’s with experience and the years.”
Kuznetsova: “I think in the start I had some options on her serve. I had love-30, 15-40, couldn’t turn it around. Then I just lost silly break, quite fast one, the first set. Then it was again everything even. Second break in the second set, it’s pretty simple. But these small moments, small chances really matters a lot. I think Garbiñe recovered very good today. She defend very good.”
[PR] Magdalena Rybarikova (SVK) def.  Coco Vandeweghe (USA) 63 63
Rybarikova: ” I just recently played ITFs in Surbiton. I was thinking that I was nervous more there than today. I have no idea how come I was that calm. Obviously I was nervous, but I was not like I would shake. Sometimes I can get really nervous and really tight. But this match I was quite positive. I was saying to myself, if I’m not going to make this serve, I still can break her because I had a lot of chances before so I can still make. If not, then I have third set. I was still up. So you still have to believe. Somehow I was not nervous. But I don’t understand it quite well, but that happened. … Always some player who surprise. Now I was lucky to be me. Yeah, I’m really grateful for that.”
Vandeweghe: “That’s why Grand Slams are the hardest tournaments. They’re over two weeks and you have to play well for two weeks. … I think (Rybarikova is) playing the best tennis of her career right now. She’s won a lot of tournaments. And she’s playing really well. She’s in the semifinals.”
