Take a look at the hilarious moment Alexander Zverev helped style Carlos Alcaraz’s hair at the Laver Cup
The 16th-ranked Nakashima was a late addition to Andre Agassi’s roster after US Open runner-up Ben Shelton withdrew last week.
Following the completion of the opening day, Alcaraz said: “I’m just trying to have fun in every place that I go and on every court that I play on.
“I don’t usually play doubles. I just try to enjoy and be better at things. I use doubles to try and improve my tennis, a couple of adjustments. Having a partner like Jakub, it’s really easy to have fun on the court.”
Wins are worth one point on Friday, two points on Saturday and three points on Sunday. The first team to reach 13 points wins.
Europe have won the Laver Cup five times while Team World won their third title in last year’s edition of the Ryder Cup-style event.
