Leading 1-0 from the first leg at the Riverside, Villa secured a goalless draw at home that was enough to book them a place in the final.
Jack Grealish and Lewis Grabban both came close to securing Bruce’s side the win before keeper Sam Johnstone escaped a red card for handling a shot outside the area in the final few minutes. Stewart Downing hit the bar from the resulting free-kick as Boro pressed but failed to find a leveller.
