The Suns stayed focused and played determined football after Rowell’s exit, taking a seven-point lead in the opening minute of the final term but missed opportunities to extend it.
A seesaw last quarter broke open in the final five minutes when Allen and then ruckman Nathan Vardy goaled before Jack Petruccelle kicked his side’s fourth consecutive major to seal victory.
