It’s going on 70 minutes after a Corona Centennial High basketball playoff victory. Fans were told to go home and escorted out by security. Doors were locked. And yet there’s loud music in the gym with basketballs bouncing as custodians clean up. All-American guard Jared McCain is going through his routine, working on his shot.

“People ask, ‘Does he do this all the time?’ Yes,” coach Josh Giles said.

When your best player is also your hardest worker, it helps explain how Centennial will be bidding for its third consecutive Southern Section Open Division championship at 8 p.m. Saturday against Bellflower St. John Bosco at Honda Center.

The Duke-bound McCain just won’t let anyone outwork him. “His after-game routine has gotten contagious,” Giles said. “It’s awesome. Our administration is great about it. They let the boys do it.”

Now freshmen players are joining McCain, and junior guard Eric Freeny is trying to beat him to scheduled practices.

“Eric and Jared battle for first guy here,” Giles said.

It’s a big weekend for basketball championships in the Southern Section and City Section. There will be lots of outstanding boys’ and girls’ teams and athletes to watch. Let’s take a look at the star power.
