And another medal chance for South Korea in artistic gymnastics, possibly gold, in the men's vault.
Shin Jae-hwan, the current world number one, qualified for final with the best average score of 14.eight-six-six.
He is expected to go with the same routine in the final round.
If he can perform as well as he has so far, he has a good chance of winning the gold in that event, which is at around 7 o'clock this evening.
If he does, he'll cement his place as one of the South Korean gymnastics greats with Yang Hak-seon, who won gold on the vault in 2012.
