The Cincinnati Reds will likely be without Hunter Greene into the month of August.

Greene was placed on the injured list last week with right hip discomfort. The pitcher is headed to Arizona for a strengthening program and will need to follow that with a throwing program of four to six weeks in length, according to a report.

The 23-year-old leads the Reds with 73 1/3 innings pitched this season, posting a 3.93 ERA and 100 strikeouts.
