Before the start of Wimbledon 2022, there was a lot of chatter about how fans would miss the greatest grasscourt player, Roger Federer, as well as banned Russian players like World No. 1 Daniil Medvedev and Andrey Rublev. But during the first week, there have been plenty of unexpected controversies which have brought the attention of tennis fans back to the action on court at the grasscourt Major. One such incident was when two-time Wimbledon champion Andy Murray played an underarm serve in his first-round match against James Duckworth, which stunned the Centre Court. While traditionalists were surprised with Murray’s actions, and a few even criticized him, most tennis fans came out in his support.Guardian sport@guardian_sportAndy Murray delighted fans at Wimbledon last night with an underarm serve.
