ONTARIO — The game went pretty much the way Los Alamitos boys basketball coach Nathan Berger expected.

Plenty of turnovers, and plenty of fastbreaks.

“Thank goodness we scored how many more points we scored than they did,” Berger said.

Los Alamitos scored three more points than Mira Costa did. The Griffins defeated the Mustangs 63-60 in the CIF Southern Section Division 1 championship game Saturday at Toyota Arena.

It is the third CIF-SS boys basketball championship for Los Alamitos. The Griffins won CIF titles in the sport in the 2006 and ‘07 seasons. Berger was a sophomore reserve on the ‘07 team.

Mira Costa committed 21 turnovers. Los Alamitos turned the ball over nine times.

As they have all season, seniors led the Griffins on Saturday. Senior guard Wes Trevino scored a team-high 15 points and blocked two shots, spectacular blocks that had Trevino reaching balls that were at their apex two feet two feet above the rim. Senior forward Trent Minter scored 14 points, nine in the first quarter, with a game-high 11 rebounds, including four offensive rebounds.

Fellow seniors Samori Guyness and Liam Gray scored 10 and nine points, respectively. Junior forward Tyler Lopez added 13 points for the Griffins.

Los Alamitos (25-8) and Manhattan Beach’s Mira Costa (29-4) will play in the CIF Southern California Regional tournament that begins Tuesday. Regional brackets will be released today.

The Griffins had a 13-point lead, 43-30, early in the third quarter. Mira Costa rallied to tie it 54-54 with 4:26 to go in the fourth quarter. Los Alanitos tried to pull away again, but Mira Costa’s Mac Bedner, fouled on a 3-point shot, made the three free throws to cut the Griffins’ lead to 58-57 with 2:50 remaining.

Trevino made a 7-foot jumper in the lane with 2:09 to go. After several missed shots by both teams, Minter made one of two free throws for a 61-57 Griffins lead with 22 seconds to go.

Mira Costa’s Christian Kranz made a 3-pointer with Minter all over him with nine seconds left to make it 61-60.

Trevino made two free throws with seven seconds remaining and a desperation 3-point try by Kranz bounced off the left side of the rim at the buzzer, to give Los Alamitos the victory.

Berger set up a challenging schedule for Los Alamitos, a schedule that Mira Costa coach Neal Perlmutter called the toughest in Southern California high school basketball. Berger said the difficult set of games contributed to the Griffins’ ability to tough out Saturday’s win.

“I think our guys were battle-tested throughout the year,” Berger said.

Minter agreed, and pointed to The Classic at Damien tournament in late December when the Griffins played in that prestigious tournament’s top, elite division.

“We played a lot of good teams there,” Minter said. “We played them close. Just seeing that we were able to play with good teams even though we were losing, that we had the grit to do it.”
