Editor's note: As the Pac-12 season enters crunch time, the Star will provide a look at the league standings, every result and each team's upcoming schedules. This is the second in a regular series.
All three of the Pac-12's ranked schools played Saturday, and two of them lost in surprising fashion.
At the same time many in Tucson witnessed Arizona's 13-point home loss — and the program's worst shooting performances in McKale — to UCLA, Oregon State pulled off an upset of No. 14 ranked Oregon in Corvallis, winning 63-53.
That opened the door for Colorado to climb in the driver's seat with four weeks of conference play remaining thanks to its home win over Stanford.
Here's a full look at the Pac-12 standings:
1. Colorado (19-5, 8-3)
Last game: W, 81-74 vs Stanford
The rundown: Colorado overcame a 16-point second half deficit against the Cardinal behind McKinley Wright IV's 21 points. Since losing to Arizona by 21in early January, the Buffs have won five of their last six games.
Up next: at Oregon on Thursday (7 p.m., ESPN)
2. Oregon (18-6, 7-4)
Last game: L, 63-53 at Oregon State
The rundown: The Ducks have now lost two in a row. Senior point guard Payton Pritchard has shot a combined 12-42 (28%) in the two defeats.
Up next: vs Colorado on Thursday (7 p.m., ESPN)
3. Arizona (16-7, 6-4)
Last game: L, 65-52 vs UCLA
The rundown: Arizona shot 25.4% against the Bruins, the lowest shooting percentage by any Wildcats team in McKale, ever. While the results of Saturday's game may suggest otherwise, the Cats remain in good position to compete for the conference title.
Up next: at Cal on Thursday (8:30 p.m., FS1)
4. ASU (15-8, 6-4)
Last game: W, 66-64 vs USC
The rundown: The Sun Devils rank second-worst in the Pac-12 in shooting percentage (42.2%) but have quietly won four of their last five. Remy Martin hit a pull-up jumper with 19 seconds left against USC to deliver the win.
