DOHA -- Son Heung-min's South Korea came back from the dead to beat Saudi Arabia 4-2 on penalties on Tuesday and join dark horses Uzbekistan in the Asian Cup quarter-finals. South Korea will face Australia in the last eight while the Uzbeks play hosts and holders Qatar after beating Thailand 2-1. Second-choice goalkeeper Jo Hyeon-woo was the hero for South Korea in Doha, saving penalties from Sami Al-Najei and Abdulrahman Ghareeb in the shootout. After a nail-biting game ended 1-1, Hwang Hee-chan scored the decisive penalty for Jurgen Klinsmann's side, who are aiming to end a 64-year Asian Cup title drought for South Korea. But they are out of the Asian Cup in the last 16 and their wait for a fourth continental crown -- and first since 1996 -- goes on.
