Why it matters for Iga Świątek
This loss is a significant upset, as Świątek was expected to perform well in the tournament.
The crowd was stunned as Eala secured her winning point, collapsing to the ground before rising to her feet to pay tribute to her opponent.
What comes next?
Eala will move on to the fourth round, making history as the first Filipino player to do so.
Clare Balding, a BBC presenter, broke the news, saying: "Let us bring you up to date with a major shock. The defending champion, Iga Świątek, is out of Wimbledon, and Alex Eala is the first player from the Philippines ever to reach the fourth round here."
Eala reflected on her childhood, saying: "I'm really emotional. For someone like Iga, who has won so many Grand Slams, or maybe like Serena or Venus, this achievement may seem small but for someone who grew up in the Philippines it is huge."
The match ended with a score of 7-6 (11-9) 6-2 in favor of Eala.
Świątek's loss is a surprise, given her ranking as the third-best women's singles player in the world.
Eala's win is a significant milestone for her and for the Philippines, marking a new achievement in the tennis world.
The tournament will continue, with Eala moving on to the next round and Świątek's loss marking the end of her Wimbledon run.
