SEATTLE -- Terrence Ross made sure on a day to honor Washington's seniors that his sophomore season at home finished with an exclamation.

Ross scored 15 of his 25 points in the first half, Tony Wroten added 22 and Washington pulled away in the final five minutes for a 79-70 win over Arizona on Saturday to cling to a share of first place in the Pac-12.

For the first time in their last four meetings, the Wildcats and Huskies didn't decide the outcome on the final possession. That was just fine by the Huskies (19-8, 12-3 Pac-12), who close the regular season with three straight road games.

Ross was nearly perfect inside the 3-point line, hitting 10 of the 11 shots he took inside the arc. He was 11 of 19 shooting overall, shaking off a sore shoulder and sore ankle.

Nick Johnson led Arizona (19-9, 10-5) with 20 points, but the Wildcats saw their five-game win streak snapped.
