Buttler has chipped in with an average of 61 and kicked off the series in style. He led England to victory in the first ODI at Edgbaston by scoring 129 off just 77 balls - the highest individual score of the series.
2. Strike rates
The average strike rate for batsmen who've batted three or more innings is a staggering 122.04. Liam Plunkett left the series after two games because of an injury but his 57 runs from the 33 balls gives him the highest strike rate so far at 172.72.
Luke Ronchi has batted in every innings and notched a strike rate of 150 to heap more misery on the bowlers. It will come as no surprise to find that Jos Buttler (146.4) and Brendon McCullum (143.93) are just behind in upsetting economy rates.
Of all 26 batsmen who have faced a delivery, 17 have strike rates of 100+ and 10 have 125+.
3. The poor old bowlers
It's often said that it's a batsmen game and this series is living proof of that sentiment. Both teams have chopped and changed their attack for one reason or another but neither has really had much success.
The Black Caps fell for 198 following England's record breaking 408-9 in game one but since then, no bowler has been able to escape the bombardment.
There's no doubt that New Zealand will miss Trent Boult. They will really miss Trent Boult. His steady economy of 5.40 and six wickets, from the 20 overs he bowled in the first two games, which makes him New Zealand's best performer with the ball by far.
Every other Black Cap bowler has struggled to prevent the relentless flow of runs. Tim Southee, Matt Henry, Ben Wheeler and Mitchell McClenaghan all have erratic economy rates ranging between 6.65 and 8.14.
England haven't fared much better but Mark Wood, with figures of 2-97 from his two games, has the lowest economy rate of just 4.85. Steven Finn has been the most consistent bowler across the series for either side and six wickets from 37 overs, with an economy of just 5.67, represents a solid return from the Middlesex seamer.
4. Williamson and Taylor
New Zealand's stand out performers oozed class in guiding the Black Caps to wins in the second and third ODIs. Their century partnership at the Oval was bettered at Southampton by their record breaking 208 run partnership.
It was the Black Cap's highest ever third wicket partnership and their highest against England.
Williamson has really announced himself to world cricket and he's now the fifth fastest man to reach 3000 ODI runs while Taylor is now one century away from levelling Nathan Astle's New Zealand record of 27 international hundreds.
5. Weren't England supposed to be cautious?
Apparently not. England haven't just ripped up their own record books, they've shredded each sheet and cut up the strips. The fourth ODI saw them pass 300 for the fourth successive game - surpassing their previous best of two.
The most runs England have ever scored in a five match series is 1399. In the four games in this five match series, they've already scored 1425 runs.
Their 408-9 in game one was their highest ever ODI score and the 350 they chased down at Trent Bridge was their highest ever chase.
