Harrell, a 6-8, 235-pound forward who signed with Rick Pitino's Cardinals earlier this month, helped the USA U18 National Team win the gold medal in the FIBA Americas Championship this week in Sao Sebastiao do Paraiso, Brazil.
Harrell, who averaged 5.4 points and 4.2 rebounds, and Team USA blitzed the field by an average of 38 points per game. They smashed host Brazil 81-56 in the championship game Wednesday night.
Despite limited minutes, Harrell finished as the team's fifth leading rebounder, hauling in 8 offensive and 13 defensive rebounds in five games. The Tarboro, N.C. native made 12-15 field goal attempts in the tournament, which tied with Memphis forward Shaq Goodwin for the team lead in field goal percentage (80 percent).
"It was great because all these guys contributed something different to the team and I think we started to realize that and we all bought in to everything coach said," Harrell said. "It was great; I had a lot of fun."
Sam Harrell said Thursday that his son will "come home for a couple days, then go to summer school" at Louisville in July.
Harrell is expected to make a big impact for the Cardinals frontcourt as a freshman.
"He won't take a backseat to Gorgui or Chane at the 5 or the 4," Rick Pitino told ESPN's Andy Katz. "He's a killer competitor. That's going to keep both of those guys on their toes every single day. I haven't had a player signed this late that will have this kind of impact."
