Europe hit back in doubles in tense Laver Cup

As many singles rubbers as needed will now be played, starting with Daniil Medvedev against Shelton, who has been the busiest of the players by far over the three days given his double prowess.

Germany's Alexander Zverev, who lost to Taylor Fritz on Saturday and complained of a fever, is due to play Tiafoe later before Alcaraz will take on Fritz if necessary.

Team Europe are again being captained by Bjorn Borg and Team World by John McEnroe. Europe won the first three editions but the World have triumphed in the last two.

The tournament, this time taking place in Berlin, switches each year between a venue in Europe and the rest of the world.
