Giovani Bernard darted through the Steelers' defense for two touchdowns and the lead. BenJarvus Green-Ellis finished them off with between-the-tackle runs.
The Bengals' backfield is starting to cause double trouble.
Cincinnati is getting quick returns on its investment in Bernard, a rookie brought in to give them more of a receiving threat out of the backfield. He led the way in a 20-10 win over Pittsburgh on Monday night.
The Bengals (1-1) brought in Green-Ellis to get some tough first downs and essentially run out the clock in the fourth quarter. Cincinnati can now run it up the middle or dump it off and let the other back make a play.
They host Green Bay (1-1) on Sunday.
