  Observational constraints on planet spin-axis has recently become possible,
and revealed a system that favors a large spin-axis misalignment, a low stellar
spin-orbit misalignment and a high eccentricity. To explain the origin of such
systems, we propose a mechanism that could tilt the planet spin-axis during
planet-planet scattering, which are natural outcomes of in-situ formation and
disk migration. Specifically, we show that secular spin-orbit resonances could
occur for a short time period during the scattering processes, and excite the
misalignment of the planet spin-axis. This typically leads to planets with
large spin-misalignment and a wide range of eccentricities and inclinations.
