Samuels came in at number three and smashed 26 from 20 balls before being bowled by Pat Cummins.
The West Indies really started motoring when Bravo came to the crease. He and Gayle hit a few long sixes to get their team to the 140-mark.
However, Bravo went for one too many as he looked to accrue a big total, and was caught by George Bailey off the bowling of Cummins.
Kieron Pollard (38) and Gayle went on the rampage in the final over, belting four sixes between them from the bowling of Xavier Doherty. Pollard was caught by David Warner with the last ball of the innings.
