Warner hit nine fours and five sixes and shared a 124-run stand for the second wicket with Kane Williamson (50) to power Hyderabad to a commanding position after they were inserted by Bangalore following a delayed start due to rain.
Playing his first game in IPL-9 after recovering from an injury, Williamson was perfect foil to Warner in an innings where he blasted seven boundaries in 38 balls.
Australian allrounder Moises Henriques then provided the late charge with a 14-ball 31 laced with three sixes and a boundary.
Earlier, opening the innings Shikhar Dhawan (11) blasted a couple of fours off Watson and Parvez Rasool before becoming a victim of Richardson in the fourth over. Looking to work a ball across the line he ended up giving a catch to the bowler.
