With Mark Lyons in foul trouble and Kevin Parrom ejected from the game, No. 8 Arizona was ripe for an upset. Nobody told Solomon Hill. Hill scored 18 points in the first half as Arizona beat Washington State 79-65 on Saturday, the Wildcats' fifth consecutive win over the Cougars. Hill made six of eight 3-pointers in the first half as Arizona built a lead it never lost.
