Iran outclass Bahrain
Carlos Queiroz's men needed until the 71st minute to seal a win that always looked on the cards at AAMI Park.
Ehsan Hajsafi opened the scoring just before half-time with a stunning effort.
A corner was cleared to Hajsafi on the edge of the area and he took a touch before looping an effort over Sayed Jaafar.
Iran looked the more likely to score a second, and a few tight offside calls went against them.
But Masoud Shojaei made it 2-0 in the second half.
Andranik Teymourian's corner found Shojaei, and he scuffed a right-footed effort in from near the penalty spot.
