The game plan for Regis Jesuit was simple: Make the Rangeview defense work. And work. And then work some more.

For three quarters, the deliberate half-court game had No. 9 Regis in position to end No. 1 Rangeview’s perfect season. Then Rangeview turned up the full-court pressure, and a Regis lead that grew as large as 12 in the fourth quarter melted away amid a flurry of turnovers and a whole lot of Marceles Duncan

The Rangeview freshman scored nine of his game-high 23 points in the second overtime, and the Raiders forced 11 Regis turnovers combined in the fourth quarter and two overtimes to escape with a 75-69 victory in Saturday’s Great 8 boys basketball epic at Denver Coliseum.

The comeback spoiled a heroic effort from Regis junior Eric Fiedler, who scored a game-high 36 points on 8-of-17 shooting from the field and 17-of-18 at the free throw line. Lucas Dickinson added 20 points and 10 rebounds on 8-of-16 shooting, but Regis’ inability to close doomed its upset bid.

Twice Regis (19-7) had the ball at the end of the fourth quarter and first overtime with a chance at a game-winning bucket. Twice the Raiders were unable to get a shot off against Rangeview (26-0).

No. 6 Mountain Vista 71, No. 3 Chaparral 57>> The Wood father-son coaching tandem is two wins away from rarified coaching air.

Golden Eagles head coach Brian Wood, who won a pair of Class 3A titles as a star player at Buena Vista under the direction of his dad Bob Wood, has Mountain Vista in the Final Four. Bob is now Brian’s lead assistant.

A championship this season would give the father/son hoops tandem a title together as coach/coach following their achievements as coach/player.

Cal Baskind had 27 points, and Oliver Junker added 17. Those efforts helped Mountain Vista (21-5) pull away from Chaparral (21-5) in the second half despite sophomore Christian Williams’ 27 points.

No. 1 Grandview 54 vs. No. 8 Denver East 34>> Grandview’s balancing act has it back in the Final Four for the third time in the last four years. The Wolves improved to 23-3.

Overmatched East (17-9) utilized a collapsing zone defense to negate 6-foot-4 senior center Sienna Betts, a candidate for national player of the year. Still, the UCLA-bound Betts did what Betts does — she grabbed 14 rebounds to go with 10 points, three blocks and three assists — while her teammates knifed the basket and made the Angels pay for their strategy.

No. 5 Pine Creek 38, No. 4 Cherry Creek 33>> It’s a brave new world for the Eagles. They played in the Great 8 for the first time and now they’re in the Final Four.

Pine Creek didn’t hold a lead until 4:20 left in the game when point guard LeeKaya Burke-Perryman made a scooping layup.

From that point on, Pine Creek controlled the game, making the big plays and sinking free throws down the stretch. Senior center Brooklyn Stewart, an Oklahoma commit, scored 10 points and pulled down 17 rebounds. Cherry Creek was led by A’Neya Chambers, who scored 11 points.

No. 7 Legend 67, No. 2 Valor Christian 59>> The Titans sent the defending champions packing as Grace Stanley and senior forward Mason Borcherding paced the Titans with 13 points apiece. The Titans improved to 21-5, while the Eagles finished 23-3.
