Antonia Sakellaridou won bronze in a mixed multi-discipline team, which does not count as an individual medal for Greece, but for "Mixed-NOC". I think this is a stupid rule in Summer Youth Olympic Games.
Savvas Thomoglou finished the heat with the second fastest time in the 200m breaststroke with a time of 2:14.94 to qualify for the finals. He has a good chance to get Greece a third medal. Fingers crossed!
