The 2009 Pac-10 tournament has its first final: No. 9 Stanford 62, No. 8 Oregon State 54.
The Cardinal took the lead with a big run at the start of the second half, and they held it the rest of the way, although the Beavers hung around.
And Anthony Goods 3-pointer in the final two minutes may have been the dagger that did the most damage.
The Cardinal and Huskies will play at 2:30 p.m. Thursday. The game will be on FSN.
In the regular season, UW beat Stanford 84-83 at home Jan. 8, and 75-68 on the road Feb. 8.
"(The Huskies) are the conference champions," Stanford coach Johnny Dawkins said. "We have to go out there and play a very very good 40 minutes. It's going to be a physical game, it's going to be hotly contested, and we have to be prepared for it."
Since the Pac-10 revived the conference tournament in 2002, the top-seed has lost its opening game twice.
