Here were the rules on tie breakers used in the Pac-10 last year (I assume they're the same):
PAC-10 TOURNAMENT STRUCTURE-SEEDING AND TIE-BREAKING PROCEDURES
Seeding: The seedings and pairings shall be determined upon completion of regular season play on Saturday, March 5. The won-lost percent- age record of the teams in regular season Conference play will determine tournament seedings. The team with the best won-lost percentage in Conference play will be seeded #1, the next best won-lost percentage in Conference play will be seeded #2, and so forth through all the seeds.
Tie-Breakers: Tie breaking procedures for determining all tournament seeding will be:
1. Two-team tie
a. Results of head-to-head competition during the regular season.
b. Each team’s record vs. the team occupying the highest position in the ␣nal regular standings, and then continuing down through the standings until one team gains an advantage.
When arriving at another group of tied teams while comparing records, use each team’s record against the collective tied teams as a group (prior to that group’s own tie-breaking procedure), rather than the performance against individual tied teams.
c. Won-lost percentage against all Division I opponents. d. Coin toss conducted by the Commissioner or designee.
2. Multiple-team tie
a. Results of collective head-to-head competition during the regular season among the tied teams.
b. If more than two teams are still tied, each of the tied team’s record vs. the team occupying the highest position in the final regular season standings, and then continuing down through the standings until one team gains an advantage.
When arriving at another group of tied teams while comparing records, use each team’s record against the collective tied teams as a group (prior to that group’s own tie-breaking procedure), rather than the performance against individual tied teams.
If at any point the multiple-team tie is reduced to two teams, the two-team tie-breaking procedure will be applied.
c. Won-lost percentage against all Division I opponents.
d. Coin toss conducted by the Commissioner or designee.
Here's a quick look:
Washington: 0-1 vs CU, 0-1 vs Cal
Cal: 1-1 vs CU (assuming we win Sunday), 1-0 vs UDub
CU: 1-0 vs UDub, 1-1 vs Cal
A 2-way with Washington gives us the #1 seed.
A 3-way tie with Cal and Washington would eliminate Washington. It would then likely go to how CU and Cal did against Oregon (4th place team). Cal's 2-0 against them and we're currently 1-0 with a road trip left. Assuming that ties, we move to 5th place Arizona. We split with Zona and Cal's 0-1, so we'd win the tiebreaker and get the #1 seed.
A 2-way tie with Cal gives us the #1 seed for the same reason the 3-way tie did.
If we win these last 4, we're in very good shape.
