Kevin Parrom matched his career best with five 3 pointers - in six tries - scoring a season-high 19 points and leading No. 12 Arizona past Washington State 73-56 on Saturday. Parrom opened the game with two 3s and the Wildcats (23-4, 11-4 Pac-12) led all the way. Arizona was up by as many as 21 points early in the second half before the Cougars cut it to 11 late. Mark Lyons added 14 points and freshman Kaleb Tarczewski had a career-best 12 for the Wildcats, who began the day tied with Oregon atop the Pac-12.
