We study a short-range site-random Ising model in three dimensions (3D) using a Monte Carlo (MC) method and find a phase transition to a spin glass (SG) phase at a very high temperature (Tc\simeq2.83 J). Values of the critical exponents estimated from a finite-size scaling analysis are different from those in both the 3D\mpJ Ising model and the 3D Ising ferromagnet. We suggest that the SG phase in this model is a new SG phase which is characterized by a nonzero SG order parameter q≠0.
