Harvey (back) is progressing well and hopes to be clear to throw a bullpen session in the coming days, Jaylon Thompson of the Kansas City Star reports.

Harvey hasn't made an appearance since Aug. 4 because of mid-back tightness, an injury that he initially suffered in late July. The right-handed reliever looks to be trending in the right direction and should have a shot to return before the end of the month if all goes well. Harvey is part of the late-inning mix in Kansas City.
