Put into bat, Umar today blasted a breathtaking 94 laced with nine boundaries and four sixes to power Pakistan to 191 for five in their stipulated 20 overs.
All-rounder Glenn Maxwell then conjured up hopes of a successful run-chase for Australia as he smashed a devastating 48-ball 74 but Pakistani spinners brought their team back into the game with some good bowling.
"The strength of Pakistan is we have too many match winners and anybody can win the match for us and today Umar Akmal showed a great talent. We always wanted him to express himself. He held his nerve very well. He attacked and that's what we wanted our boys to do. He has got great talent and he was simply unbelievable today," he added.

"The start we had, 40 for 2 after seven overs, I'd have taken that. You just try and play your best bowlers and Pakistan's spinners bowled very very well and also Umar Gul in the death," he said.
"Batting and bowling go either way, but fielding was in our hands and we've set high standards and we didn't do well today. This is probably from our point of view the most disappointing aspect of our game today," he said.
Umar Akmal, adjudged Man of the Match, said he played his natural game and dedicated the award to his brother Kamran.
"I would like to dedicate the award to my brother Kamran Akmal who is making a comeback in the team in the world cup," he added.
