Novak Djokovic is now 17-0 in first-round matches at the French Open.
The No. 1-ranked Djokovic opened his quest for a 19th Grand Slam title and second in Paris by defeating Tennys Sandgren of the United States 6-2, 6-4, 6-2 in just under two hours on Tuesday night.
Djokovic saved all six break points he faced and compiled a total of 33 winners in the last match of the clay-court tournament's first round.
Djokovic will face Pablo Cuevas next.
The match against Sandgren was in Court Philippe Chatrier as part of the new scheduled night sessions at the French Open. It was played without spectators in the stands, though, because of a 9 p.m. local curfew as part of COVID-19 restrictions.
