At the other end, the Bears made their first five shots to open with a 17-2 run, going up 50-40 on Crabbe's four-point play.
"We took ill-advised shots," Arizona coach Sean Miller said. "It looked as if we had no idea what we were during for that brief three-minute period."
The Wildcats clawed their way back with a 9-2 run to stay within reach, but never made it all the way back.
Arizona pulled within two on a 3-pointer by Lyons with 2:02 left, but Crabbe answered with a tough baseline drive and Cobbs followed with his layup that made it 75-69, sending the Bears to their biggest road win of the season.
