The portable mounting stand apparatus of this invention is adapted to receive a ball return apparatus for the like thereon and provide means for ease of movement from a portable transport condition to a rigid usage condition. The portable mounting stand apparatus includes a main support base assembly; a forward base support assembly secured to a forward portion of the main support base assembly; and a rearward base support assembly connected to a rear portion of the main support base assembly. The forward and rearward base support assemblies are each provided with support wheel assemblies to contact a support surface for ease of movability in the transport position. The rearward base includes a pivotal stationary support assembly having a pivotal stand support assembly which is selectively actuated to move support leg assemblies into and out of contact with the support surface. When in the rigid usage conditon, the pivotal stationary support assembly acts to elevate the rearward support wheel assemblies out of contact with the support surface so as to present a rigid nonmoving structure for use of the ball return apparatus, for example, on a basketball court in a basketball practice drill session.
