Last year’s women’s champion and men’s runner-up, Garbine Muguruza and Marin Cilic, both crashed out of the Wimbledon second round on Thursday.

Third-seeded Muguruza was stunned by Belgium’s world No. 47 Alison van Uytvanck 5-7, 6-2, 6-1 on Court No. 2, while men’s No. 3 seed Cilic lost 3-6, 1-6, 6-4, 7-6 (3), 7-5 to Argentina’s Guido Pella, who had never won a match at Wimbledon prior to this week.

“I think she played big today. She took a lot of risk, and it worked for her. I also think that my level today was not where I wanted it to be. That’s also why she could develop that kind of level,” said Muguruza of Van Uytvanck, who had only ever won one match at Wimbledon before this tournament.

“But, yeah, is a little bit sad because I wanted to, you know, really go out there. But I think she played great. Think she played great.”

Cilic was in control of his second round against Pella when it started on Wednesday evening, going up two sets but play was suspended by rain, with the Croatian trailing 3-4 in the third set (a break) and the momentum completely shifted when play resumed on Thursday.

“Yesterday the match started so bad for me because he was playing so good, very solid from the baseline with big serves, and I couldn’t do almost nothing,” said the 28-year-old Pella, who is into the third round at a Grand Slam for the first time in his career.

“So the rain came, and today was very different day because I started to feel very good. Just at the beginning of the fourth set — I close the set in the third with big serves, with big two games. Then I started to feel better and better. I saw him playing like a little bit slower than the day before. So I tried to fight every ball, tried to be close in the score, and that’s it.”

Cilic, who was one of the top contenders for the title and won Queens in the build-up to Wimbledon, admits he wasn’t able to summon his best on court after the restart on Thursday.

“I was just not feeling as comfortable as yesterday with hitting. I was not as accurate. I was just missing some balls, some easy balls, giving him a chance to come back. That was playing the part. It was not just the pressure. It was me not executing on the court well,” said the world No. 5.
