Maybe it’s time to believe the hype on Carlos Balderas.

And if you haven’t heard any of the love being given to the 19-year-old American boxer, then feel free to learn more about this guy before his quarterfinal fight on Friday.

Team USA is now 4-0 after Balderas beat 26-year-old Japanese fighter Daisuke Narimatsu to advance to within three fights of going for a gold medal in lightweight boxing at the Rio Olympics.

Balderas advanced to fight Narimatsu with another upset, beating 30-year-old Kazakh fighter Berik Abdrakhmanov.

Lazaro Alvarez of Cuba is next, and the 2012 bantamweight bronze winner presents a massive challenge. Not only is Alvarez expected to medal — so was Abdrakhmanov — but the Cuban has fought one less fight in this compressed tournament.
