  Multi-orbital Hubbard models are shown to exhibit a spatially isotropic
spin-triplet superconducting phase, where equal-spin electrons in different
local orbitals are paired. This superconducting state is stabilized in the
spin-freezing crossover regime, where local moments emerge in the metal phase,
and the pairing is substantially assisted by spin anisotropy. The phase diagram
features a superconducting dome below a non-Fermi liquid metallic region and
next to a magnetically ordered phase. We suggest that this type of
fluctuating-moment induced superconductivity, which is not originating from
fluctuations near a quantum critical point, may be realized in spin-triplet
superconductors such as strontium ruthenates and uranium compounds.
