McDermott delivered, posting a season-high 34 points, his most since scoring 36 in a BracketBuster win over Long Beach State last February.
Crabbe did not, scoring just 14 points on a season-low 23 percent shooting (6-of-26). His previous worst was a 4-of-13 performance (30.8 percent) in the semifinals of the DirecTV Classic against Georgia Tech.
Crabbe, who missed his first 12 shots and all eight of his three-pointers, couldn't recall a worse game in his career and labeled his performance "unacceptable.
"I apologized to my team after the game, told them I took some questionable shots," Crabbe said. "I'll change for the betterment of the team.
"I just missed shots. It was just an off night. There were some shots I usually make."
Creighton head coach Greg McDermott said the goal was to hold Crabbe and guard Justin Cobbs under 50 percent shooting from the field, a target the BlueJays (10-1) more than exceeded as the Golden Bears' two leading scorers were a combined 14-of-43.
"We got them frustrated early," Doug McDermott said. "Cobbs had a really good game, but we kept Crabbe in check. That was our main goal."
Unexpected Return for Kreklow
After missing the last five games because of soreness in his right foot, redshirt sophomore guard Ricky Kreklow played for the first time since Nov. 16 on Saturday night.
Kreklow returned to practice Thursday after an ultrasound and second opinion revealed he could not aggravate the injury, though it might not be fully recovered for up to four weeks.
"We had anticipated a couple minutes here, a couple minutes there," said Montgomery, who ended up using Kreklow for 15 minutes, largely to defend McDermott. "He does make a difference for us in terms of creating activity."
Kreklow finished with four points and five rebounds before fouling out.
All Signs Positive for Cobbs
Cobbs hit his head on a cameraman's knee after making a lay-up with 23.1 seconds left to play. The redshirt junior did not return to the game, but Montgomery and Crabbe both said Cobbs seemed to be okay.
"He seemed pretty fine in the locker room," Crabbe said.
Montgomery indicated that Cobbs would likely be put through concussion protocol.
"You know how that is going these days," Montgomery said. "They wouldn't allow us to put him back in, so that was the end of that. It doesn't mean there is anything wrong, but if you hit your head, they are going to make you go through all the tests."
Improvement On Defensive Glass
After allowing at least 11 offensive rebounds in each of their last four games, Cal limited Creighton to just six offensive rebounds and three second-chance points.
It was just the third game this season in which Cal held an opponent under double-digit offensive rebounds, after allowing six at Denver and a season-low five in the quarterfinals of the DirecTV Classic against Drake.
