Jessica Pegula has revealed a back pain incident during her campaign at the US Open 2025. This came during Pegula's quarterfinal match against Barbora Krejcikova, which she went on to win in straight sets.
Pegula won both sets 6-3 to win the match convincingly and clinch her second victory of her career over Krejcikova to qualify for the semifinals. However, during the course of the match, an unprecedented situation occurred with Pegula during the first set of the match.
Speaking on a podcast, days after the conclusion of the US Open, Pegula revealed that she was forced to take a bathroom break. The American player further added that it was due to a back spasm, and owing to which she laid down on the bathroom floor to get some exercise, even though the floor was very dirty. She said (via The Player's Box Podcast, 12:20 onwards):
"So when I was playing (Barbora) Krejcikova, it was like 3-3, no, I'm sorry, 4-3 in the first set, and so luckily I ended up winning the set 6-3, and I took a bathroom break. I never take bathroom breaks, maybe like count on one hand, the amount of bathroom breaks I have taken in my entire life."
"So I went to the bathroom slowly because I needed to lay down on the floor and do some core exercises because my back was spasming up. I did like core and activation stuff. So, I took two towels with me, and there were towels in there, and the bathroom of Ashe was like gross, so I lay down the towels."
Notably, after her victory over Barbora Krejcikova in the quarters, Jessica Pegula went on to lose her semifinal match against Aryna Sabalenka in three sets 6-4, 3-6, 4-6.
