USC Trojans 78, Arizona Wildcats 65

In a rematch of last year's Pac-12 tournament title game, USC exacted some revenge on Arizona.

The Wildcats started both halves sluggish, and the Trojans took full advantage on their way to securing a spot in the quarterfinals.

USC took control of the game early on by grabbing an early 11-point lead within the first nine minutes of the first half.

Sean Miller's squad did not go away quietly, though, rallying to even the score by halftime.

However, Arizona would dig itself a hole early in the second half that it could not climb out of.

Behind the strength of eight points from senior Bennie Boatwright, USC started the second half on a 23-5 run. 

Arizona managed to close the gap to 13 a few times, but the Wildcats were never able to put the pressure on the Trojans and get it back down to single digits. As a result, Arizona failed to win a game in the conference tournament for the first time since Miller's first year in Tucson back in 2009-10.

Boatwright finished with a game-high 22 points and added 11 rebounds, with junior guard Derryck Thornton (12 points) among those contributing to the victory. Senior forward Ryan Luther had 16 points in a losing effort for Arizona.

The win earns USC a matchup with top-seeded Washington on Thursday.

Colorado Buffaloes 56, California Golden Bears 51

In a game in which neither team could muster much on offense, it was Colorado that managed to score just enough to survive and advance.

The Golden Bears managed to jump out to an early lead by scoring the first six points of the game, but McKinley Wright IV led the Buffaloes back and then some. Wright scored nine of his team's first 12 points thanks to a trio of three-pointers in the first eight minutes.

California shot just 32 percent from the floor in the first half, resulting in 22 points. While a poor shooting performance like that could have led to a blowout, the Golden Bears went into the locker room only down six at half.

Matt Bradley and Co. made a game of it by cutting the deficit down to one on a couple of occasions early in the second half, but they were never able to complete the comeback and regain the lead. Wright helped power Colorado to an 8-0 run near the midway point of the second half:

The Buffaloes would grow their lead to 10, but the Golden Bears did no go down without a fight.

Cal made it a one-possession game coming out of the under-four timeout. That set the table for a nail-biting finish.

Although the Golden Bears had a chance to tie the game late, a pair of Tyler Bey free throws in the final seconds iced the game.

Wright led all scorers with 18 points, and Bradley put up 17 to lead the Bears in a tough loss.

Colorado will now take on fourth-seeded Oregon State for a spot in the semifinals.

UCLA Bruins 79, Stanford Cardinal 72

After the two teams split their regular-season meetings, UCLA earned bragging rights over Stanford with a 79-72 victory in the rubber match on Wednesday.

And this was a game the Bruins controlled from start to finish.

UCLA set the tone early by scoring the first seven points of the game. Stanford would fight back to even the score at 11, but the Bruins begin to pull away shortly after. They ended the half on a 19-9 run to take a 12-point lead into the break.

And just like at the start of the game, UCLA showed up ready to play in the second half.

The Bruins opened the second half on a 21-9 run as they grew their lead to 26 points just more than six minutes into the half.

The Cardinal trimmed the deficit to single digits late and made things interesting by getting it down to six in the final minute. However, Stanford could not close the gap enough to make it a one-possession game. As a result, UCLA was able to escape with the win after holding off a late rally.

Jaylen Hands had a game-high 22 points, with Chris Smith (14), Kris Wilkes (12) and Jalen Hill (12) all reaching double figures for the Bruins as well. Josh Sharma led Stanford with 18 points and 13 rebounds.

The victory advances UCLA to the second round, where it will take on second-seeded Arizona State.

Oregon Ducks 84, Washington State Cougars 51

Oregon surely needs to win the Pac-12 tournament to reach the Big Dance, and it took the first step toward making that a reality with a commanding 84-51 victory over Washington State.

The game was never in doubt, as the Ducks jumped out to an 18-3 lead and didn’t look back. They extended the advantage to 17 points by halftime and continued to build on it after intermission, leaving no doubt they would be part of the quarterfinals in Las Vegas.

Oregon’s bench did much of the heavy lifting on the offensive side with Ehab Amin spearheading the scoring with 17 points, Will Richardson adding 10 points and five assists, and Miles Norris scoring 14 points.

The loss capped off a dismal season for the Cougars after they went just 4-14 in conference play during the regular season. They struggled to create open looks against Oregon’s hounding perimeter defense and finished a mere 7-of-32 (21.9 percent) from deep and never mustered any serious comeback attempt.

CJ Elleby led the way in a losing effort with nine points, nine boards and two steals.

Attention now turns to a quarterfinals showdown between the Ducks and Utah Utes. The Utes are the No. 3 seed, but Oregon won the only regular-season matchup between the two in Utah back in January thanks in large part to 19 points from Richardson on 8-of-12 shooting from the field.

If he plays like that in the rematch, the sixth-seeded Ducks will have the chance to advance to the semifinals.
