SEATTLE (Ticker) -- Lute Olson will have to wait at least another week to make Pac-10 Conference history.
Tre Simmons scored 24 points and Nate Robinson added 22 as No. 13 Washington edged eighth-ranked Arizona, 93-85, preventing the Wildcats from clinching the Pac-10 regular-season title.
Despite a career-high 30 points from Channing Frye, the Wildcats (24-5, 14-3) were unable to earn Olson a 305th win in Pac-10 play. The Hall of Fame coach tied UCLA legend John Wooden at 304 league wins with a 57-56 overtime triumph at Washington State on Thursday.
With the win in this one, Washington (23-4, 13-3) pulled even with Arizona in the loss column, ensuring it can do no worse than a tie for first were it to win at California and Stanford next week. The Wildcats finish their regular season at Arizona State next Saturday.
Arizona trailed by 13 points early in the second half but pulled within 75-74 on a 3-pointer by Mustafa Shakur with 4:58 remaining. But Frye was whistled for goaltending on a hook shot by Brandon Roy on Washington's ensuing possession, and after a fruitless possession by the Wildcats, Robinson nailed a 3-pointer for a six-point cushion with 3:42 remaining.
Robinson's key shot from the arc came after senior center Hakeem Rollins made an impressive save of an offensive rebound that was going out of bounds.
"Hakeem Rollins had that unbelievable putback," Washington coach Lorenzo Romar said. "That might have been the biggest play of the game."
The Wildcats reduced the deficit to 84-81 on a 3-pointer by Salim Stoudamire with 1:43 remaining, but the 5-9 Robinson answered with a layup over the 6-11 Frye. Arizona's Ivan Radenovic missed two free throws and Robinson sank a pair for an 88-81 lead with 35 seconds to play.
Hassan Adams scored 18 points and Stoudamire 15 for Arizona, which shot 53 percent (37-of-70) but allowed Washington to connect on 57 percent (34-of-60).
Paced by Simmons (5-of-10) and Robinson (3-of-6), the Huskies made 11 of their 24 attempts from the arc. The Wildcats made just 6-of-23 3-pointers.
"It was a great college basketball game, a great environment," Olson said. "I don't think either team was going to give an inch to the other team. In the end it was a case of Washington doing a better job of knocking down threes."
The Huskies capped their home slate this season at 15-0 and posted their 22nd consecutive home win, including 16 straight in league play.
"We are a group that has character," Romar said. "It has character, is together and is pretty mentally tough, which is what it takes to beat a team like Arizona."
Arizona, which made a school-record 38-of-40 free throws in a 91-82 home win over Washington on January 27, connected on only 5-of-11 in this one.
The Wildcats held a 31-30 lead after a jumper by Radenovic with 4:32 left in the first half, but the Huskies scored nine straight points and took a 42-35 edge into the break.
