In the men’s singles event, the players finishing in first position in each of the 20 groups qualify for the main draw; those in second places progress to a preliminary round. The 10 preliminary round winners plus two “Lucky Losers”, drawn at random from that round, join the 32 seeds in a first round of 64 players.

Rather differently, in the women’s singles competition, the players finishing in first position in each group plus one “Lucky Loser”, drawn at random from the second placed players, join the 16 seeds in an opening round of 32 players.

Meanwhile, there are four seeded players in each of the under 21 men’s singles and under 21 women’s singles events, in the former players finishing in first place in each of the four groups advance to the quarter-finals; in the latter players concluding matters in top spot in each of the three groups, plus one “Lucky Loser” drawn at random from the second placed, players progress.
