American swimmer Michael Phelps has won his third gold medal of the Olympics and smashed another world record.
He came first in the 200 metres freestyle, finishing nearly two seconds ahead of South Korea's Park Tae-hwan in a time of 1 minute 42.96 seconds.
Phelps is only the fifth athlete to win nine gold medals in his career. And he only has to win one more to become the most successful Olympian ever.
But he's still a few short of his goal - he wants eight golds this Games.
Elsewhere at the Games there were no more medals for Team GB on Tuesday, but the British women's hockey team did do well.
They came back from behind, to draw 2 all with Argentina to keep their hopes alive.
Great Britain now face a make-or-break match against New Zealand on Thursday before final matches against Japan and the US.
