Playing without injured quarterback Ben Roethlisberger for a third consecutive week, the Steelers turned to 37-year-old Batch for the second game in a row. He went 25-of-36 passing for 276 yards and one touchdown, and he also moved the Steelers 61 yards before Suisham's game-winning kick.
Pittsburgh trailed 13-3 in the first half and 20-13 in the fourth quarter before coming back to win.
The Ravens could have clinched a playoff berth with a victory. Instead, Baltimore had its 15-game home winning streak halted and also lost for the first time in 13 games against division foes.
