No one can defend Steelers wide receiver Mike Wallace in a foot race. Don't even try. His 95-yard touchdown catch in the second quarter was the longest pass in Steelers history. Wallace has one catch for at least 40 yards in six straight games.
The Steelers should've had another interception in the first half, but safety Troy Polamalu dropped a pass that hit off his chest.
The Cardinals responded to that Wallace score with a 13-play, 80-yard drive to cut the lead to 14-7 near the end of the first half. Starting running back Beanie Wells went into the locker room with an undisclosed injury before halftime after running for 42 yards on 12 carries.
But Pittsburgh never let go of the momentum too long. A 41-yard field goal ended the half.
The Steelers had four first downs as the result of Arizona penalties in the first half.
