British junior Hannah Klugman suffered defeat on her WTA main-draw debut as she lost to Yulia Putintseva at the Nottingham Open.
The 16-year-old, runner-up in the French Open girls final earlier in May, fell 6-2 6-2 to world number 27 Putintseva in the first round.
Klugman is one of a number of highly rated British juniors, having won the prestigious Orange Bowl junior championships in Florida aged 14.
But Putintseva was a step up in quality, with the Kazakh winning the Birmingham Classic title on grass last year.
“I felt very uncomfortable on my first match on grass, having done a long period on clay, so I struggled today,” Klugman said.
“It was a tough one against a top player – I’ve never played against someone like that.
“The crowd was amazing, as was the court. I just wish I could have played better.”
