  Starting from the quasi one-dimensional kinetic energy of the d_{yz} and
d_{zx} bands we derive a bosonized description of the correlated electron
system in Sr_2RuO_4. At intermediate coupling the magnetic correlations have a
quasi one-dimensional component along the diagonals of the basal plane of the
tetragonal unit cell that accounts for the observed neutron scattering results.
Together with two-dimensional correlations the model consistently accounts for
the normal phase specific heat, cyclotron mass enhancement, static
susceptibility, and Wilson ratio and implies an anomalous high temperature
resistivity.
