The Black Cats then had a penalty appeal when Michael Chopra tangled with Alexandre SongBillong in the area but referee Keith Stroud was not convinced.
SongBillong made it 3-1 from close range after benefiting from a ricochet off Hyypia and then Aliadiere was controversially ruled onside before pulling back to Baptista, who slid into an empty net to cap a remarkable end to the half.
