Payamps' back has been "so-so" recently according to manager Charlie Montoyo, which has led the Blue Jays to not use him, Mitch Bannon of SI.com reports.
Payamps hasn't pitched since June 17, and Montoyo revealed Friday that the right-hander's lack of usage is due to an injury. The issue apparently hasn't been serious enough to warrant a trip to the injured list, but it's not yet clear when he'll be able to return to the mound.
