PARIS (AP) — Novak Djokovic has set up another showdown against Rafael Nadal at the French Open. They will meet in the semifinals. The top-seeded Djokovic advanced by beating No. 9 Matteo Berrettini 6-3, 6-2, 6-7 (5), 7-5 in a quarterfinal delayed for about 20 minutes in the fourth set Wednesday while the first spectators allowed to attend a French Open night session were cleared out of the stadium because of a COVID-19 curfew. Nadal dropped a set in Paris for the first time in two years but defeated No. 10 Diego Schwartzman 6-3, 4-6, 6-4, 6-0.
