  Based on a weak coupling calculation, we show that an accidental degeneracy
appears between even- and odd-parity superconductivity in the quasi-1D limit of
the repulsive Hubbard model on the square lattice. We propose that this effect
could be at play on the quasi-1D orbitals Ru $d_{zx}$ and $d_{zy}$ of Sr2RuO4,
leading to a gap of the form $\Delta_\text{even} + i \Delta_\text{odd}$ which
could help reconcile several experimental results.
