  We consider a strings-junction holographic model of probe baryon in the
finite-temperature supersymmetric Yang-Mills dual of the AdS-Schwarzschild
black hole background. In particular, we investigate the screening length for
high spin baryon composed of rotating N_c heavy quarks. To rotate quarks by
finite force, we put hard infrared cutoff in the bulk and give quarks finite
mass. We find that N_c microscopic strings are embedded reasonably in the bulk
geometry when they have finite angular velocity \omega, similar to the meson
case. By defining the screening length as the critical separation of quarks, we
compute the \omega dependence of the baryon screening length numerically and
obtain a reasonable result which shows that baryons with high spin dissociate
more easily. Finally, we discuss the relation between J and E^2 for baryons.
