At the Olympics, the South Korean baseball team will play the United States tonight, looking to defend their title starting at 7 PM.
It's a complicated system in Olympic baseball.
Despite losing to Japan on Wednesday in their first semifinal game, they have another chance.
The final is on Saturday.
If Korea win tonight, they'll go to the gold medal match, but if they lose, they'll be competing for bronze.
Korea have already lost to the U.S. once in Tokyo, so it'll be a tough game.
South Korea is expected to start Lee Eui-lee, a young pitcher who had a successful game against the Dominican Republic in the knock-out stage.
