TUCSON, Ariz. -- Rob Gronkowski matched a school record with three touchdown catches, Nic Grigsby ran for 113 yards and a touchdown and Arizona routed winless Washington 48-14 on Saturday night. Willie Tuitama completed 17 of 21 passes for 193 yards and threw three touchdown passes for the Wildcats (4-1, 2-0), who are looking to end the Pac-10's longest active bowl drought at nine years. On a breezy night in the desert, Arizona wasted little time putting away the woeful Huskies (0-5, 0-3). Arizona took a 10-0 lead midway through the first quarter when Gronkowski caught a screen pass and raced 37 yards for a touchdown. Grigsby added a 4-yard run to give Arizona a 17-0 lead after one quarter.
