Last year's Trinity-Mission League Showcase was at the Intuit Dome in February. It was a success in so many different ways. Thousands of high school basketball fans came to enjoy top-notch hoops in a state-of-the-art facility at a fraction of the price it would cost to watch an NBA game in Steve Ballmer's masterpiece — the home of the Los Angeles Clippers.

The day was dedicated to seeing Mission League and Trinity League schools partake in league competition. And while that's all fine and well, there was something about the grandiose nature of the event that still felt like it was missing something ...

The powers that be nailed it this season. Instead of league games, the 'Trinity-Mission League Challenge' will be exactly that — a challenge that might settle the debate: Which league is better? This year's soiree will highlight the two leagues clashing against each other in an all-day event at UCLA's Pauley Pavilion on Saturday, November 22.

"We are thrilled to announce the inaugural Trinity-Mission League Challenge. This event will provide a platform for some of the best student-athletes in Southern California to compete in a world-class venue," tournament director Dan Shell said. "The schedule promises a day full of thrilling basketball, and we’re excited to welcome both returning and new teams to this incredible event at the iconic venue of UCLA’s Pauley Pavilion.”

Crean Lutheran and Campbell Hall are two programs that will compete in the event against each other, but neither team is in the Trinity or Mission League. Alemany and Chaminade — two Mission League programs — are not participating in the event.
