UCLA finished its regular season on Wednesday with a win over USC, leaving the Bruins with nearly eight days until their first game in the Pac-12 Tournament.

They now know who they’ll likely face next Thursday at 2:40 p.m. Arizona State clinched the No. 5 seed today when it beat Cal and Stanford lost to Arizona. That matches the Sun Devils up against the 12th-seeded Trojans on Wednesday at the MGM Grand Garden Arena; the winner will advance to face No. 4-seeded UCLA.

USC only has five conference wins in two seasons under Andy Enfield, none of which have come against their crosstown rival. ASU beat the Bruins in their only meeting this year, taking a 68-66 decision in Tempe.

If UCLA wins that Thursday game, it will almost certainly draw No. 1 seed Arizona in the semifinals — assuming that the Wildcats dispatch either Cal or Washington State. An upset by the Bruins to reach the Pac-12 title game would move the team off the NCAA Tournament bubble.
