It’s a little splendor in the grass for Garbine Muguruza…

The 21-year-old Venezuelan-Spanish professional tennis player upset former World No. 1 Caroline Wozniacki in the fourth round at Wimbledon, reaching the last-eight at the prestigious All-England Club for the first time in her career.

Muguruza, seeded No. 20, defeated No. 5 seed Wozniacki in straight sets, 6-4, 6-4.

Both players had opportunities in a tight opening set, but it was Muguruza that took hers, claiming the solitary break when the Dane framed a forehand beyond the baseline. Despite a lapse in concentration at the start of the second, Muguruza displayed her growing maturity by wrestling back the momentum, producing a brilliant game – including one inspired backhand lob – to break for a 5-4 lead, then holding her nerve to serve out the match in a fraught final game.

“It means a lot because I haven’t played a lot matches on grass, so I didn’t know how to prepare for Wimbledon,” Muguruza said. “I think it’s like the third time I play here. So for me was something new. That’s why it’s special.

With the win, Muguruza becomes the first Spanish woman to reach the quarterfinals at Wimbledon since Conchita Martinez – who was announced as the new Spanish Davis Cup captain on Monday – in 2001.

Muguruza’s victory means it’s guaranteed that the Wimbledon ladies’ finalist from the bottom half of the draw will be ranked outside the top 10.

Muguruza next faces Swiss No. 15 seed Timea Bacsinszky after she fought back from a set down to beat Romanian Monica Niculescu 1-6, 7-5, 6-2.

The other quarterfinal match in the bottom half will be contested on Tuesday by big-serving American Madison Keys and Poland’s Agnieszka Radwanska.
