Novak Djokovic, Rafael Nadal and Roger Federer all are in the same half of the French Open men’s field. That means only one of them could reach the final. It is the first time the Big Three all wound up in the same half of the bracket at any Grand Slam tournament. Nadal beat Djokovic in the 2020 final for a 13th championship at Roland Garros. This year, they could meet only in the semifinals. Federer and Djokovic could play in the quarterfinals. Serena Williams has familiar faces in her quarter of the women’s bracket. The tournament starts Sunday in Paris.
