Pututau added 22 points for the Mustangs, and he scored eight of his points in the final 4:20, including the buckets that tied the score at 59 and 63 and two more baskets after that to momentarily give the visitors a pair of one-point leads at 65-64 and 67-66.
Tanner Knowles was also in double digits for Mountain Crest (2-1) with 15 points and six rebounds. He scored 10 points in the first quarter and all 15 of his points in the first half before smacking his head on the floor and sitting out much of the fourth quarter with concussion-like symptoms.
Coach Larsen admitted that when his team got up by 18 points late in the third period, they may have subconsciously thought the game was over and let up a little bit.
"I think our kids did, too, and that was kind of the problem," he said. "We got a little lax and Crosbie got it going, and like the good player that Crosbie is, he took it upon himself that he was going to make a run by himself and he did. We did force him into taking 25 shots to get his 25 points, but there for awhile I didn't think he was going to miss anything.
"We've got some special kids. Hayden has taken over the leadership role — I don't think anybody questions that — and he made a play, but we had a couple of our other kids make a play, too. Tesch got the layup and a free throw. Jaren made a play even though he made a little mistake there stepping across the (free-throw) line. And Beckey made a free throw. And we're going to have to count on those guys, so it's great experience for them. And then obviously Hayden's going to be our catalyst and he opens up so much for everyone else and we're going to play off that.
"The second half, they did a good job," Larsen said of the Mustangs. "We'll never apologize for a win, whether they're ugly, pretty, whatever, we'll take it. I give Mountain Crest a lot of credit because they could've easily folded up and they came back and kicked out butt in the second half, and we were fortunate enough to make a couple plays from the free-throw line late to hang on, and that's exactly what we did is hung on.
"It felt like a playoff game or a league game to me. That team's not gonna quit; I'm so impressed with that Mountain Crest team, and with our kids, too. Our kids didn't hang their heads; when they needed to they made a play."
Schenck, who's now averaging a whopping 33.7 points a game through three contests, connected on 16-of-19 free throws on his way to another 30-point night. He was 7 of 12 from the field and also had six assists and five steals.
"He does a lot of great things," Larsen said of his 6-foot-3 star senior guard. "He makes everyone a better coach, that's for sure.
"He's aggressive in transition and he doesn't shy away from contact, and he does a great job getting to the free-throw line."
After pouring in 22 first-half points, Schenck credited the Mustangs' defense with making some adjustments, which made things much tougher for him in the second half.
"They played hard-nosed 'D'. ... They doubled me and I tried to get the ball to my teammates to make a play, which they did," Schenck said. "Tesch and Jaren and Garrett made the plays at the end of the game.
"I just try to run our offense and coach says whenever you get a good look, take it and, if not, try to get your teammates open and get them looks. ... And my teammates have been doing a great job."
Schenck wasn't surprised by the way Crosbie got the hot hand in the second half.
"He's a great player," Schenck said. "I've been playing with him since first grade. Me and him played little league together and he's a great player. He's one of those kids that can shoot and you've got to respect him all the time because he can come on whenever. ... That's a good win for us."
Although his team is still undefeated after three games, coach Larsen says there's plenty of room for improvement.
"We're not gonna complain," he said, "but, like probably every 3-0 team in the preseason, they're gonna say we've got a lot to work on."
Like learning how to protect a double-digit lead, for starters.
