Mirra Andreeva was the last person on Centre Court to realize she had won her fourth-round match against Emma Navarro on Monday, a result that made her the youngest woman since 2007 to reach the Wimbledon quarterfinals.

So locked in and focused was Andreeva that she didn't realize she had won the match. Andreeva, up 6-2, 5-3 and 0-40 with Navarro on serve, won the point—and the match—when the American's attempted approach shot on a short ball was deposited into the net.

Mirra Andreeva oblivious to the fact she’d won after swatting aside Emma Navarro - The 18-year-old Russian was preparing for the next point, oblivious to the fact she had reached the quarter-finals at Wimbledon.
