Novak Djokovic defeated Soonwoo Kwon as he reached the second round of Wimbledon on Monday afternoon.
The Serbian champion, a 20-time major winner, struggled to assert his dominance, with Kwon going up in the first and second set, but each time the 3-1 advantage was repelled.
Djokovic had struggled since his return to full-time tennis after a troubled time with coronavirus regulations but he is now through to the second round.
He will face the winner of Thanasi Kokkinakis and Kamil Majchrzak.
