His name is known well among Milwaukee sports fans, or so they think.
Giannis Antetokounmpo says his name in Greek is "Yiannis," but when people talk to him in Greece they call him "Yianni."
He says a lot of people in American don't understand this, but he's grown to get used to it.
"Look, it doesn't matter," said Antetokounmpo. "Both of them are the same to me."
He says some of the Bucks players call him Yianni, but for the most part he's Giannis.
