England Women rewrote the records books as Tammy Beaumont and Lauren Whitfield scored centuries in the second Royal London One-Day International 212 run success over Pakistan Women at New Road, Worcester.
England's total of 378-5 from 50 overs was their highest ever in ODI cricket as they established a winning 2-0 lead in the best of three series.
It also forms part of the ICC World Championship and England have climbed to third spot in table behind Australia and the West Indies with the top four automatically qualifying for the 2017 World Cup in England.
England surpassed their previous highest total of 376-4, also against Pakistan in 1997 at the Ghandi Stadium in Jalandhar, India.
The previous highest 50 over score in all cricket at New Road was also beaten – Worcestershire's 365-7 against Scotland in the Friends Provident Trophy in 2007.
Then Anya Shrubsole finished with the excellent figures of 4-19 as Pakistan were dismissed for 166 in 47.4 overs.
England's series win with a match to spare – at Taunton on Monday – was the ideal start to the new era under skipper Heather Knight who had been the star performer in the opening win at Leicester yesterday.
Beaumont and Winfield figured in a superb opening stand of 235 in 39 overs and then Natalie Sciver smashed a brutal 80 off just 33 balls.
None of the Pakistan bowlers escaped punishment with Nina Dar conceding 78 in seven overs and Asmavia Iqbal 88 in 10 overs.
Winfield and Beaumont became the 16th and 17th players to score ODI hundreds for England.
Beaumont had the distinction of achieving a career best score for the second game in a row.
She had scored 70 in the opening ODI yesterday and went to three figures off 114 balls with nine fours and two sixes.
Winfield's previous highest score had been 31 against the West Indies three years ago.
But she produced an innings full of quality and attacking strokes and brought up her hundred off 106 deliveries with 11 fours and two sixes.
Beaumont and Winfield batted with such assurance that England's record opening ODI stand of 268 by Sarah Taylor and Caroline Atkins against South Africa at Lord's looked under threat.
But the partnership was broken on 235 in the 39th over when Beaumont (104) attempted to pull Maham Tariq and was caught at backward square leg.
In the same over Winfield's fine knock ended on 123 when she was caught at short third man.
But Sciver ensured there was no let up in the onslaught and she brought up her half century off just 22 balls with three sixes and six fours.
Knight (26) helped her add 84 off just 33 balls before being bowled by Asmavia Iqbal.
The record score was achieved in the 50th over before Sciver was run out off the final ball of the innings having hit six sixes and seven fours.
Pakistan faced a daunting task and did not help their cause when Nahia Khan was run out with eight on the board attempting a single after Sidra Amin turned Katherine Brunt to backward point.
Anya Shrubsole trapped Amin (11) lbw and then Sciver struck in successive overs.
Javeira Wadood (26) was caught at long on and Iram Javed ( 5) perished on the mid wicket boundary.
Bismah Maroof provided strong resistance and reached a fine half century off 71 balls with six fours.
But after making 61 she flicked Brunt to mid wicket and then skipper Sana Mir (21) was run out by Danni Wyatt's direct throw from backward point.
Sidra Nawas (4) was bowled by Brunt, who finished with the excellent figures of 2-27 from 10 overs, and Nida Dar (8) lofted Shrubsole to mid-off.
Shrubsole enjoyed a third success when Sadia Yousaf (1) perished at cover and she wrapped up the game as Tariq (2) was trapped lbw.
