Mohammad Haris hit a swashbuckling maiden international century to guide Pakistan to a 3-0 clean sweep of Bangladesh with a seven-wicket win in the third and final Twenty20 international in Lahore on Sunday.

Haris, playing in his 17th T20I, carted seven sixes and eight fours in his 107 off just 46 balls as Pakistan chased down a challenging 197-run target in 17.2 overs for their first home T20 international series win in three-and-a-half years.

Pakistan won the first two matches by 37 and 57 runs at the same venue.

"It's a massive win," said Pakistan captain Salman Agha.

"I am very happy the way the boys played. The great thing is we managed to play the brand of cricket we wanted to play and we did well in every game."

Bangladesh skipper Litton Das did not hide his disappointment at losing the series 3-0.

"We did bat well in this game but didn't bowl and field well," said Litton. "Losing a series is always disappointing."

Parvez Hossain smashed four sixes and seven fours in his solid 34-ball 66 to lift Bangladesh to 196-6 in their 20 overs.
