Alexander Zverev beat Daniil Medvedev in five grueling sets on Centre Court. The match ran long. It is currently his to lose. His opponent will be Britain’s unseeded Arthur Fery. Both men say they will contend intensely for the trophy. Fery, 23, qualified with a series of shock wins. Zverev relied on big serves and quick groundstrokes to wear down Medvedev. The German is now waiting for Fery and the grandest stage at Wimbledon.
