Second-shot opportunities were also instrumental in jump-starting the UA offense. Bret Brielmaier snagged an offensive board, and two passes later Mustafa Shakur converted a three that gave Arizona a 19-9 lead.
Salim Stoudamire drained another three of an offensive rebound as the UA built a 24-9 lead. Meanwhile, Richmond could get nothing going offensively. It didn't reach double figures until the 7:25 mark of the first half. A Chris Rodgers three gave Arizona a 27-11 advantage.
Richmond got into the lane on a couple consecutive possessions in the waning moments of the half to trim the Wildcat margin to 27-21, but a deep Stoudamire three stemmed the Spider run with 4:30 left. Radenovic was the story. He tallied 14 points and six boards at the half, and Arizona entered the locker room up 42-26.
Richmond turned in a couple successful early possessions, but then the Wildcats rolled off the eight quick points. However, they then lost a turnover in transition that led to a Spider three-point play and technical foul on Radenovic. As a result, the five-point possession trimmed the UA advantage to 50-35, and momentarily helped to keep the game in reach.
Any hopes of a dramatic rally were short-lived. The UA built a 20-point lead in quick fashion and pretty much coasted down the stretch.
Rodgers scored a career-high tying 20 points. Ravenovic and Stoudamire added 16 apiece.
The Wildcats held Richmond to less than 40 percent shooting from the floor and registered a double-digit steal tally for the third straight game.
