LOS ANGELES (Ticker) -- Matt Lottich prevented second-ranked Stanford from needing another dramatic victory.

Lottich converted a key three-point play with 2:19 remaining as the Cardinal pulled away for a 70-63 victory over Oregon in the Pacific 10 conference tournament semifinals.

Stanford (28-1) has made a habit of winning games in the final minute this season and seemed on its way to another thriller after Oregon forged a 61-61 tie with just under three minutes remaining.

Lottich followed with the decisive play, blocking Luke Jackson's 3-pointer and taking the ball to the other end for layup. He was fouled and buried the free throw for a 64-61 edge.

"Everyone was scrambling on the play and I saw Luke with the ball," Lottich said. "He is so clutch and I knew if he got (the shot) up he would make it."

"I didn't even see (Lottich)," Jackson said. "Looking back, I should've pulled it out and tried to get a good shot. That was just one of a few mistakes that were made in the last four or five minutes that gave Stanford the confidence to believe they could beat us."

Joe Kirchofer made a hook shot and Josh Childress sealed the game with a pair of free throws with 20 seconds left as Stanford advanced to the conference final, where it will face Washington.

Stanford has won 27 games for just the fourth time in school history and the first since 2001, when it had a school-record 31 victories.

Childress finished with 18 points and Lottich had 15 despite 5-of-13 shooting for the Cardinal, who shot 47 percent (27-of-57) from the floor while holding the Ducks to 36 percent (21-of-59).

Andre Joseph scored 16 points, but Jackson was held to 12 on 4-of-14 shooting as Oregon (15-12) had its chances of an NCAA Tournament berth dashed.

"We knew coming into the game that (Jackson) was an integral part of their offense," Childress said. "We had to work on limiting his opportunities in the game."

The Ducks had 24-23 edge at halftime after a defensive-minded first half, but the Cardinal stepped up their offense in the final 20 minutes, making 17-of-31 shots and 10-of-15 free throws.

"I'm proud of my guys because they did a tremendous job in matching Stanford's energy and work ethic," Oregon coach Ernie Kent said. "They really hung in there and battled. It was just a defensive slugfest for the first 25 or 30 minutes."

The teams were tied eight times and exchanged the lead seven times in the second half before Lottich's play on both ends of the court put Stanford ahead for good.
