Mirra Andreeva was the last person on Centre Court to realize she beat Emma Navarro on Monday, a result that made her the youngest woman in 18 years to reach the Wimbledon quarterfinals. Andreeva was so focused on not thinking about the score — and avoiding looking at Roger Federer — that the 18-year-old Russian didn't grasp that the fourth-round match was over when Navarro netted a forehand.

Emma Navarro, the daughter of billionaire Ben Navarro, was defeated in straight sets by 18-year-old Mirra Andreeva in the fourth round at Wimbledon on Monday.
