Humphrey said his team's fast start gave the Cards a boost and set the tone for the remainder of the contest.
"We hit some perimeter shots and that kind of got us going," he said.
In addition, Humphrey liked his team's rebounding effort, especially on the offensive end.
"I really liked how we attacked the offensive glass on our missed shots," the Clark coach said. "I felt like we could hurt them on the glass, and we did."
Stenzel, who led all scorers with 22 points, scored five of those during the first of two 13-0 scoring blitzes by the hosts. Stenzel tallied 20 points in the opening half and knocked down three of the Cards' 10 shots from long range.
The Thorobreds, led by former Clark coach Mike Reitz, rallied on the shoulders of Julian Talbott and narrowed the margin to 27-19 with 3:43 remaining in the first half. However, Clark's Robert Hatton connected with a three-point play underneath to stretch the margin back to double figures.
"His shot selection has been excellent," Humphrey said. "We have all of the confidence in the world (in him) when he pulls that trigger."
Reitz wasn't surprised by Clark's response to his team's comeback attempt in the second frame.
"The bottom line was: Clark is a very good basketball team," he said. "They're one of the top two or three teams in the region and we're basically in the middle of the pack. It's just that they're a very good team."
Hatton and Miller followed Stenzel's lead with 11 points each.
Talbott, who led the guests with 20 points, had 18 of his team's 23 points in the opening half. Talbott scored just one field goal in the second half.
"He's a good athlete and a good player," Reitz said. "He gives it 110 percent every time he goes down the court. It's a shame we wasted his effort tonight."
Harrison (9-14) closed the gap to 36-25 to open the third quarter, but the Cards delivered the proverbial knockout punch with another 13-0 spree to put the game out of reach.
"At halftime, we talked about regaining focus, and in the third quarter, we came out and did that," Humphrey said.
The Cards played without freshman Corey Rogers, who sat out because of an illness. Humphrey said he hopes to have Rogers back in time for his team's regular-season and home finale Thursday against Louisville Ballard.
