Bronny James’ much-awaited college debut will be remembered for plenty of excitement, but also a painful loss.

With 21 seconds left, it looked like James might be the Southern Cal hero when he hit two free throws to put the Trojans up, 74-72, over visiting Long Beach.

However, Marcus Tsohonis (former VCU player) tied the game up at the buzzer and Long Beach won in overtime, 84-79. Tsohonis finished with 28.

Playing before a sold out Galen Center crowd, including Bronny’s famous father, LeBron, and other family members, the 6-foot-4 freshman scored four points in 16 minutes.

Wearing jersey No. 6, he also grabbed three rebounds, handed out two assists, made two steals and blocked a shot.

James was returning to competition after suffering cardiac arrest in a practice session July 24.

With the loss, USC falls to 5-5. James dressed but did not play in the first nine outings. USC’s next game will be Sunday, Dec. 17, at Auburn, Ala., with a 1 p.m. tipoff.
