Stanford has beaten Cal twice this year, both times it was 3-2.
Once in Hawaii and once at home.

ETA:
cbvb.com/bracket is listing the odds for each pair match-up.  (This is based on TruVolley computer rankings of the players, which don't have a great reputation for accuracy.)  Anyway, they predict Cal winning the 1s (55.5% probability) and Stanford winning the others (66-75% range each).

They also give a slight edge to FSU over USC, but some of the pairs are almost even.
