Norman had plenty of chances in the final minute to tie it as the Timberwolves missed the front end of a pair of one-and-ones in the last 20 seconds of regulation.
But the Tigers couldn't take advantage and Norman North closed out the regular season with the win.
“It was too tight there at the end with us not hitting our free throws, but as long as we got the win, that's all that matters,” Dickinson said.
Dickinson, one of those freshmen, finished with a game-high 15 points. Junior Kairo Rutledge had 10 points and 13 rebounds.
Norman had four players in double figures — Sam Blodgett (14), Cooper Clark (13), Jay Finley (10) and Daniel Harper (10) — but only got two points from the rest of its roster.
