Pac-12 Tournament Quarterfinals Open Thread

After yesterday's 11-hour marathon of tournament games, we're back at it again today. Here's your schedule for the day:

Thursday, March 13: Quarterfinals
Arizona vs. Utah, 12 p.m., Pac-12 Network
California vs. Colorado, 2:30 p.m., Pac-12 Network
UCLA vs. Oregon, 6 p.m., Pac-12 Network
Arizona State vs. Stanford, 8:30 p.m., Fox Sports 1

What happened when they met previously?

Arizona defeated Utah twice, 65-56 and 67-63 in OT.

Cal defeated Colorado at home 66-65 in OT last weekend..

UCLA defeated Oregon 70-68 in January but Oregon got revenge in an 87-83 double-overtime victory.

The Lobsterbacks beat ASU 76-70 at home but lost 76-64 on the road.

We'll obviously have a separate thread for the Cal game. For everything else, this is your open thread.
