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.

Mirra Andreeva and several other stars will join an elite group after reaching the quarter-final of Wimbledon for the first time. Any player who makes it this far automatically becomes a member of the ‘Last 8 Club’, a tradition started back in 1986.
