Berrettini, who beat Taro Daniel and Federico Coria in the first two rounds in Paris, was made to work hard in the first set against Kwon, who saved three break points in the second game and four break points at 5-5. Berrettini won the first three points of the tie-break and led 6/3, before Kwon recovered to 6/6. The Italian wrapped up the set with a forehand drop shot winner.
