David Warner smashed his first international ton since completing a ball-tampering ban as Australia edged Pakistan by 41 runs at Taunton.
Warner (107) and Finch (82) got Australia to a cracking start with an opening stand of 146.
Mohammad Amir then pulled Pakistan back into the game with career-best five-wicket haul but Australia still got to 307, which ultimately proved too much for their opponents.
