Three players - Lubomir Jancarik, Bence Majoros and Yang Wang - booked their spots in the Olympic men's singles table tennis contest on day three of the qualification tournament in Doha.
Three knockout brackets - each with one Tokyo 2020 berth - were completed today and the Czech Republic's world number 94 Jancarik was the first of these, defeating Ukraine's world number 56 Lei Kou 11-5, 14-12, 11-9, 11-6.
Hungary's world number 61 Majoros also enjoyed a convincing victory, this time over five games, against Belgium's world number 104 Florent Lambiet.
Majoros triumphed 11-6, 11-7, 11-9, 8-11, 11-8.
Slovakia's Wang - kicked out of the World Table Tennis Contender tournament earlier this month for breaching coronavirus regulations - had the toughest challenge of the three qualifiers.
Wang went a game down before eventually prevailing against Greek world number 49 Panagiotis Gionis 3-11, 11-5, 11-9, 6-11, 11-6, 11-7.
Later in the day, Gionis advanced to the semi-finals of the second stage of qualification with a 12-10, 11-7, 11-6, 8-11, 17-19, 12-10 win over Romania's Ovidiu Ionescu.
Lambient similarly enjoyed a 7-11, 11-9, 11-9, 11-3, 5-11, 11-8 victory over Niagol Stoyanov of Italy.
This second stage will award the final spot in the men's singles at Tokyo 2020, giving a second chance for the losing semi-finalists and finalists from the first knockout rounds.
Britain's world number 15 Liam Pitchford bounced back from a shock defeat yesterday to make the final four with a 11-4, 6-11, 11-4, 11-4, 11-4 win over Russia's Vladimir Sidorenko.
Kou suffered his second defeat of the day, being knocked out by Kirill Skachkov; the Russian world number 55 won 11-3, 13-11, 11-9, 12-14, 11-5.
The second stage of the women's singles started today too with the semi-finals.
The last women's singles spot at the tournament is set to go to either Maria Xiao of Spain or Suthasini Sawettabut of Thailand following their respective wins.
World number 72 Xiao was part of an all-Spanish clash with world number 77 Galia Dvorak, bouncing back from two games down to win 3-11, 4-11, 11-7, 11-9, 12-10, 11-3.
Sawettabut won 4-11, 11-9, 11-9, 11-9, 11-9 against Margaryta Pesotska of Ukraine.
