Taillon (calf) has been throwing on flat ground and is expected to be cleared for mound work soon, MLB.com reports.
Taillon has been sidelined for the entirety of July with a right calf strain. Cubs manager Craig Counsell said at the time Taillon went down that the pitcher would miss at least a month of action, and given where the righty is at in his throwing progression, it seems likely that he'll require a little more time than that.
