SACRAMENTO — San Gabriel Academy had a 13-point lead midway through the fourth quarter.

At the end of the game, its lead was down to one point.

That was enough for the Eagles to survive a chaotic ending as they barely held on to beat King’s Academy 52-51 in the CIF State Division III championship game Friday at Golden 1 Center.

The Eagles won their first CIF State boys basketball championship, although they were outscored 16-2 during a stretch late in the final quarter, and finished the season 21-13.

King’s Academy, a private school in Sunnyvale, finished 27-5.

San Gabriel Academy 6-foot-11 sophomore Mahamadou Diop scored 20 points, grabbed 13 rebounds and blocked 7 shots. He was 10 of 16 from the floor, including a few entertaining dunks.

Diop, who has offers from Texas Tech and UC Riverside, was the only Eagles player to score in double figures. Senior guard Coco Britt scored eight points. Sophomore guard Xavier Wang scored seven points, including two free throws with 11 seconds left to give the Eagles a three-point lead, 52-49.

The Eagles defense was good for most of the game, holding King’s Academy to 31% shooting.

Back-to-back baskets by Diop gave San Gabriel Academy a 48-36 lead. That’s when the unraveling began for the Eagles. The King’s Academy press began creating turnovers that led to baskets for the Knights, and San Gabriel Academy committed several costly fouls.

King’s Academy junior guard Claxton Ladine made a 3-pointer with 20 seconds to go to cut the San Gabriel Academy lead to 50-49.

Wang made his two free throws to make it 52-49 and the Knights’ Karan Kolappa put in a layup at the buzzer for the final one-point margin.

“Lost some years off my life there,” San Gabriel Academy coach Daniel Piepoli said.

Piepoli regretted calling the team’s final timeout late in the contest when Wang dived on a loose ball. The officials signaled the timeout just before a jump ball would have been called.

“I went to the scorer’s table and said I hope that doesn’t come back to bite me,” he said. “And it definitely did. We didn’t have a timeout to stop them, try to draw something up.”

The game appeared to be headed for a one-sided result early when San Gabriel Academy built a 17-point lead in the second quarter. King’s Academy got hot in the third quarter and reduced the lead to four points in the quarter.

King’s Academy pulled within four points again in the fourth quarter before San Gabriel Academy did a better job of taking care of the ball and resumed using its height advantage to regain control.

San Gabriel Academy took the lead for good, 12-10, on one of Diop’s many dunks, the final points of the opening quarter.

Diop’s two-handed dunk started a 14-1 run for the Eagles that moved them to a 24-11 lead midway through the second quarter.

The Eagles’ lead reached 17 points, 31-14, at one point and was 31-18 at halftime.

The teams combined for 46 turnovers, 25 by San Gabriel Academy.
