Carlos Alcaraz secured his first win against a top-10 opponent since the Australian Open final in a 6-3 4-6 (11-9) thriller against Taylor Fritz as Team Europe secured a narrow 7-5 lead heading into the final day of the Laver Cup. Fritz's only career victory over Alcaraz came during Team World's win over Europe in last year's Laver Cup, but Alcaraz saved two match points against the American and came out on top in a Saturday that featured six match-deciding tiebreaks in eight matches. The Spaniard served an ace on Fritz's first match point and then used a drop shot to save another, and Alcaraz finally won it on his third match point when Fritz got to his drop shot but couldn't get it back.

Earlier, it was all Team World - which is captained by Andre Agassi - as Alex de Minaur had a 2-6, 7-6 (5), 11-9 comeback victory over Alexander Zverev and Learner Tien outlasted Flavio Cobolli 6-3, 2-6, 10-7. In the final match of the day, Zverev partnered with Casper Ruud to beat Alexander Bublik and Brandon Nakashima 6-4 6-6 (9-7) in the crucial doubles match that secured Team Europe the overnight lead.
