CLITHEROE'S Alex Hartley made her England debut as Heather Knight's side made it three consecutive 50-over victories against Pakistan.
The 22-year-old finished with 0-53 from her 10 overs as England won by 202 runs to make it three consecutive victories.
It was Tammy Beaumont who stole the show as she became the first England women player to hit back-to-back one-day international centuries.
The 25-year-old, who was dropped on two and 64, made the most of her good fortune by posting an unbeaten 168 from 144 balls - the second-highest score by an Englishwoman in ODI cricket.
In the end, England won by 202 runs with Pakistan, in reply to England's mammoth 366 for four, bowled out for 164 in the 45th over as Katherine Brunt returned five for 30 at Taunton.
Having won the toss on a typically flat Taunton wicket, England found few difficulties in coping with the Pakistan attack.
Beaumont and Lauren Winfield, who put on 235 for the first wicket at Worcester last week, made a decent start before the latter became the first of Sana Mir's two victims, caught by Maham Tariq at mid-off for 43, with the score on 59.
Thereafter, there was precious little over which to enthuse for the tourists as England made the most of the friendly conditions and some desperately poor fielding.
Beaumont passed 50 off 70 balls and featured in a thrilling 166-run partnership with Georgia Elwiss, who struck 77 from 78 balls until she was bowled by Mir at 225 for two in the 39th over.
The arrival of Natalie Sciver brought even greater agony for Pakistan. With Beaumont in full flow, the pair added 119 off just 58 balls in 39 minutes. Sciver struck six fours and a six in her innings of 48 off 22 deliveries.
Beaumont posted her century off 111 balls, with nine fours, and reached 150 off 133 deliveries with a further eight boundaries.
Pakistan, who were never likely to trouble England's considerable total, found themselves in early trouble when Brunt held on to a regulation catch to dismiss Sidra Ameen off Anya Shrubsole.
The score was 19 for two when Shrubshole struck again, Javeria Khan finding the hands of Winfield, before the hostile Brunt had Nain Abidi caught behind by wicketkeeper Any Jones off an attempted hook, leaving the score 22 for three.
Faced with a near impossible situation, Pakistan did their best to make a decent fist of things. Bismah Maroof and Sidra Nawaz added 74 off 92 balls for the fourth wicket and Nawaz and Mir 21 for the fifth.
However, when Nawaz departed, bowled by Laura Marsh for 47 in the 31st over, Pakistan's hopes of getting within 150 had all but disappeared.
Marsh returned figures of three for 29 and Shrubsole two for 20, but the experienced Brunt was the standout performer for England with the ball.
