The Owls likely found Liberty (10-8, 6-4) to be a pesky team in the second half.
Westminster had a 51-40 lead with about two minutes remaining in the second half, but the Lions cut the deficit to 50-46 in the final seconds of the period on a Jack Selby free throws. The Owls had a 11-point lead in the middle of the fourth quarter before Liberty enjoyed a 5-0 spurt to cut the bulge to six.
Westminster, however, finished strong and pulled away.
"We especially wanted to get the win on senior night," Westbrook said. "We didn't want to lose the last time on our home court."
The first half was a different story for the hosts.
