England 170 for 3 (Knight 43) beat Pakistan 144 for 5 (Javeria 57, Glenn 2-12) by 26 runs
Pakistan pushed England close but could not prevent defeat and a 3-0 whitewash in the T20I series in Kuala Lumpur. Javeria Khan top-scored in the match with 57, but England kept a grip on the scoring rate to close out the game.
England, who rested Nat Sciver and Katherine Brunt for the final game, produced an all-round effort with bat and ball. Captain Heather Knight made 43 from 31 balls and the rest of the top five all chipped in with solid contributions, before Anya Shrusbole, Sarah Glenn and Sophie Ecclestone shared five wickets to disrupt Pakistan's chase.
The tour also allowed England's new head coach, Lisa Keightley, who is due to take up the role in January, to have a first look at the players after she joined up with the team following the conclusion of the Women's Big Bash League.
"I think it's been a good tour for us," Knight said. "We asked batters to get big runs and that's happened across both the ODI and the IT20 series.
"I think we've found some new players, as well. Sarah Glenn has really put her hand up and that's great for us, it adds to the competition for places and makes us stronger as a group.
"I've been proud of how we've maintained our high standards, especially in the field - which is something we've been working hard on.
"It's been great to spend time with Lisa and get chatting to her about how she sees the plans moving forward. We're looking forward to the new year and the challenge of the ICC Women's T20 World Cup in Australia."
After Danni Wyatt had lashed 25 off 15 to get England going, the main plank of the innings was provided by an 81-run partnership between Knight and Amy Jones. Knight hit three sixes in her innings, and while both fell in consecutive overs, Fran Wilson and Tammy Beaumont added another fifty stand in the closing overs.
Pakistan lost both openers inside the Powerplay, and were struggling at just past the halfway way point when Bismah Maroof was stumped off Glenn to leave them 68 for 3. Javeria's measured innings kept them in the hunt but despite Sidra Nawaz cracking 19 off 7 balls at the end, Pakistan had left themselves too much to do.
