The Borah and Rocky Mountain boys basketball teams rolled into the 5A District Three championship game with dominant victories Saturday night at Borah High.

A much-anticipated rematch between the Grizzlies (19-3) and Lions (21-1) - who split during the regular season - is set for 7 p.m. next Friday.

Here is a recap of Saturday's district semifinals:

ROCKY MOUNTAIN 56, EAGLE 38

It is almost hard to believe that E.J. Boyce is a first-year letterman for the Grizzlies.

The 5-foot-11 junior guard averages a team-best 11.8 points per game, which ranks 10th in the 5A Southern Idaho Conference.

And on Saturday night, Boyce tied a school record with seven 3-pointers in Rocky Mountain's victory over the Mustangs (12-10).

Boyce was 7-for-9 from 3-point range and 9-for-12 from the field for a game-high 25 points.

"His performance was spectacular. Our offense wasn't great tonight and he put us on his back," Rocky coach Dane Roy said. "The beauty of him tonight was he was great defensively as well. ... I know he can shoot like that, but when he plays defense and fights and was tough, he's a special player."

With the win, the Grizzlies secured a spot in the state tournament for the second time in program history. Rocky last made an appearance in 2010, finishing with a win in the consolation game.

BORAH 56, CENTENNIAL 39

The Lions earned the right to defend their district and state titles with a win over the Patriots (12-10).

Borah led just 18-17 after the first quarter before limiting the Patriots to four points in the second quarter. The Lions also kept Centennial scoreless for more than six minutes during an 11-0 run spanning the second and third quarters.

Foul trouble plagued the Lions early as Patrick Muteba and Kai Corpus both picked up two fouls in the first quarter. But seniors Nick Burt and Zak Studebaker provided a spark from the bench. Burt finished with nine points, and Studebaker added a pair of 3-pointers.

"I love their play tonight. We would not have won without them," said Borah point guard Isaiah Wright, who had 17 points. "Burt was rebounding like crazy, hitting open shots and same with Studie. They were really big for us tonight."
