A serving cage placeable on a service court area of a standard U.S. Lawn Tennis Association tennis court for capturing tennis balls served into the service court. The serving cage has a collapsible barrier forming a rectangular configuration in plan when in an uncollapsed, operative mode, but is capable of being collapsed into a generally planar mode for storage and transport. The barrier includes a plurality of fence sections each of planar, rectangular configuration and pivotally connected to a pair of adjacent ones of the sections, with the barrier being formed in two halves each of which halves is substantially the same size as the other of the halves in plan, but one of the halves being substantially twice the height from the service court surface than the other of the halves of the barrier.
