Defending champion Novak Djokovic overcame an early fright to fend off British teenager Jack Draper and launch his quest for a sixth title at Wimbledon.
The first match on Centre Court since Djokovic's nailbiting victory over Roger Federer in the 2019 final - was classic David versus Goliath material.
The clash ended 4-6 6-1 6-2 6-2 in the Serb's favour.
It proved the perfect way to bring Centre Court back to life after the enforced silence due to the COVID-19 pandemic.
Only 7,500 fans were permitted on Centre Court in line with the 50 per cent cap on attendance.
