Duffy (back) will start a rehab assignment with Triple-A Iowa on Monday, Tony Andracki of Marquee Sports Network reports.

EDGE Analysis

A lower back strain has sidelined Duffy since May. It's unclear how many games he'll require on the rehab assignment, but an activation when he's eligible July 22 remains realistic. Duffy hit .278 with 12 RBI in 90 at-bats before suffering the injury.
