Wimbledon has brought about more shocks in the earlier rounds than we're used to seeing but the top seeds are still alive.
Novak Djokovic made light work of Denis Kudla, winning in straight sets on Centre Court, while Ashleigh Barty has looked just as impressive as she did when she won at Roland Garros.
Thursday's action will bring about some truly enticing matches, with Rafael Nadal and Nick Kyrgios going head-to-head in what has been dubbed a 'grudge match' following their past disagreements.
British number one Johanna Konta gets her second outing on Centre Court as she faces Katerina Siniakova, while Cameron Norrie remains the highest-ranked Briton in the men's draw against eighth seed Kei Nishikori.
Andy Murray is set to make his Wimbledon return today as well. The two-time men's singles champion will partner Pierre-Hughes Herbert in the doubles against Marius Copil and Ugo Humbert. The court for that match are still to be confirmed, but play is not expected to start before 5.30pm.
Standard Sport will bring you live coverage on Day 4 at SW19, and here’s what we have in store…
