But they endured back-to-back heartache, with their 2024 United Cup final loss to Germany now followed up by a loss to the USA.
Swiatek looked forward to playing against Gauff, but she just fell short in their singles opener, losing 6-4, 6-4.
Taylor Fritz then beat Hubert Hurkacz to secure the trophy, representing the USA’s second United Cup success.
Not only did Swiatek lose to Gauff, she worryingly took a medical time out during the match, having been suffering with a leg injury throughout the tournament.
The Pole has since provided an update, saying in her post-match press conference: “Well, for sure, I wasn’t fresh today, but I’ll be good. So nothing happens.”
