Carlos Alcaraz, making his first London appearance of 2026, partnered with Jakub Mensik to secure a doubles victory at the Laver Cup. The pair defeated Taylor Fritz and Alexander Bublik with a 6-4 6-4 scoreline, contributing to Team Europe's 3-1 lead over Team World after the opening day.
Alcaraz, a seven-time Grand Slam champion, returned to action at the US Open following a four-month wrist injury lay-off that saw him miss Wimbledon and Queen's. He expressed his enjoyment of playing doubles, stating, "I am trying to have fun every place I go and every court I play on and especially doubles."
Earlier in the day, Casper Ruud secured a 6-7 (4) 6-4 10-8 victory over Francisco Cerundolo for Team Europe. Rafael Jodar also contributed to Europe's strong start, defeating Alexander Bublik 6-2 6-3. Team World's only win came from Brandon Nakashima, who beat Mensik 6-1 3-6 10-7.
