Team Europe's Carlos Alcaraz and Alexander Zverev lost their doubles match at the Laver Cup on Friday, which happened to be Alcaraz's debut in the tournament.
Taylor Fritz and Ben Shelton of Team World won in straight sets, 7-6 (7/5), 6-4 in Berlin, bringing the overall score in the tie to 2-2.
Fritz and Shelton hit 20 winners against Zverev, the world number two, and Alcaraz, ranked third.
"We both served really well under pressure. Ben served incredibly well, so I didn't have to hit any volleys. That was huge," said Fritz, as quoted by AFP.
