DUBAI, UAE – No.4 seed Agnieszka Radwanska’s Dubai campaign was cut short in the round of 16 after suffering one of the biggest upsets of the Dubai Duty Free Tennis Championships against 17-year-old CiCi Bellis.

“I didn’t feel good from the beginning. I didn’t play really great, and I was trying everything. I did what I could today,” Radwanska told press after the defeat.

She added, “For me it was really hard to control the ball and make the angles. And also, my serve didn’t work at all. In those kind of tight matches, you need those things. When you don’t have it and you’re struggling pretty much from the beginning, then you have a problem.

“I was really struggling myself. I was really focusing on myself today, but I just wasn’t good enough.”

First Top 10 Win!

Despite playing against an unseeded teenager, experience told Radwanska to be wary, especially with the way Bellis had climbed the rankings and made a name for herself toward the end of last season.

“I never really think of the seeds or unseeded players,” she explained. “In today’s tennis, we don’t have ‘easy draws’ or ‘open draws.’

“Maybe you can say this from an outside [point of view], but on the court, there’s nothing ‘open.'”

Radwanska had only words of praise for Bellis, who is the youngest member of the WTA Top 100 and the youngest player to defeat a Top 10 opponent since Belinda Bencic posted back to back wins over Angelique Kerber and Jelena Jankovic at the 2014 US Open.

“Very solid. Very consistent. She can really play good rallies with good intensity, and I think that’s a really good thing for that kind of young player. I think she was the best today.”

Putting the loss behind her, Radwanska plans to stop by her home in Poland for a couple of days before making the trip to California for the BNP Paribas Open in Indian Wells.
