A stage tool operable with a plug is used for cementing a tubing string in a wellbore annulus. The tool can have a housing with a closure sleeve movably disposed in the internal bore of the housing. When pressure is applied downhole to the tool, a breachable obstruction on an exit port of the tool's bore opens and allows fluid such as cement slurry to communicate to the wellbore annulus. When cementing through the open tool finished, a plug deployed downhole lands on a seat in the closure sleeve, and applied fluid pressure in the tool's bore against the seated plug closes the closure sleeve relative to the housing's exit port. Rotational catches between the housing's bore and the closure sleeve prevent the closure sleeve from rotating. Preferably, an intermediate sleeve is used in the housing's bore and has rotational catches on each end. When the closure sleeve moves closed, the intermediate sleeve is also moved to engage between the catches on the end of the closure sleeve and the catches on a shoulder of the housing's bore. In further arrangements, a hydraulic mechanism on the tool can facilitate movement of the closure sleeve in response to a fluid pressure component.
