Pratt (hamstring) is expected to return from the injured list sometime in late August, Adam McCalvy of MLB.com reports.
Manager Pat Murphy said Tuesday that Pratt is making good progress in his recovery from a strained right hamstring, but he's still likely multiple weeks out from returning to the starting lineup. With Joey Ortiz (back) also dealing with an injury, David Hamilton and Ji Hwan Bae have seen an increase in playing time recently.
