The England skipper led from the front as his team took a 1-0 lead in the three-match series.
Morgan's superlative knock, along with valuable contributions from Jonny Bairstow (44) and Dawid Malan (54*), helped England chased down the massive 196-run target and paved way for a 1-0 lead in the three-match series.

"Am I hitting the ball as sweetly as I ever have? Definitely. The numbers definitely back this up, even before this series started, and certainly within T20 cricket," ESPNcricinfo quoted Morgan as saying.
"The last two years in international cricket are my best numbers to date. That's great because if I can combine a little of that form with my experience, I think that will go a long way to winning games. It's nice that I am feeling good but it's actually replicated in the numbers as well," he added.
Morgan walked out to bat at No.4 with the score 66/2 and Pakistan bowlers looking to put the new man under pressure.
However, he adjusted swiftly to the situation and never let the asking rate become too uncomfortable for his team's liking.
In all, the 33-year-old smashed 6 fours and 4 maximums through his innings before being dismissed near the victory post.
England's only 50-over World Cup-winning captain and one of their finest limited-overs batsmen said his experience came to good use once again.
"It's about having experience and confidence in the roles that I play," he said. "Before I became captain, I didn't feel that comfortable jumping up and down the order."
"But now that it's my decision I feel more at ease, particularly when I am moving up and down the order between No. 4 and No. 6. I'd feel more comfortable if I was slipping down to No. 6 with Jos Buttler coming in ahead of me than I would beforehand," Morgan added.
The third and final T20I will be played on Tuesday (September 1).
