Rodney threw one perfect inning with a strikeout, recording a hold during a rehab assignment Wednesday with Class A Inland Empire. A strained upper back shelved the 34-year-old righty on June 13, and he hasn't pitched for the Halos since June 8.
His return will be a welcome addition to a bullpen seeking middle-relief answers.
"He's ready," Angels manager Mike Scioscia said. "If he feels good coming out of it tomorrow -- which we anticipate he would -- we'll activate him."
Rodney compiled a 4.09 ERA in 22 innings for the Angels before he was injured.
