In their first 20-over contest since the whitewash defeat to Bangladesh in March, England got off to a flying start, taking three wickets in the powerplay.
Glenn Phillips top-scored for the visitors with 41 off 38 before falling to Luke Wood, who finished with three wickets alongside Durham quick Brydon Carse.
Although Jonny Bairstow was dismissed early on, Dawid Malan’s 54 off 42 balls put England in the driving seat along with Harry Brook’s unbeaten 43 off 27 balls, giving the hosts the advantage going into the second T20 at Old Trafford on Friday.
Despite being given an early scare when Finn Allen smashed three consecutive sixes off the first over, a change of ends in the fourth helped Wood kick off a dominant powerplay for England.
The Lancashire bowler took the first wicket of the evening as Devon Conway feathered behind to Jos Buttler and more wickets tumbled when Carse resumed from the Finchale End to earn his first T20 international scalp for England after clean-bowling Allen.
Wood struck again to send Tim Seifert’s bails flying as New Zealand were suddenly 38 for three after six overs.
Their woes continued when Moeen Ali clipped Mark Chapman’s off-stump in the eighth over but Phillips and Daryl Mitchell tried to regain control with some good running to keep the scoreboard ticking over.
Liam Livingstone ended the partnership, however, tempting Mitchell into looping the ball to long-off aiming for a six, but Brook was on the boundary to comfortably catch.
Phillips was the dominant batter at the crease looking to keep his foot on the gas, but he was beginning to run out of partners when Mitchell Santner sliced the ball straight to Wood off Adil Rashid.
Wood’s return in the 17th over saw Phillips eventually fall for 41 after Sam Curran made an excellent dive to his left.
Carse was handed the ball for the final over and ended Ish Sodhi and Adam Milne’s quickfire 26-run partnership, taking both of their wickets to finish with figures of three for 23.
Set 140 to chase, Bairstow opened the batting, smashing four off Tim Southee, but was caught out by the Black Caps captain as he edged to Mitchell at slip.
Aiming to capitalise on their positive start, Milne and Southee restricted England to singles but the introduction of Lockie Ferguson saw Will Jacks suddenly tee off, smashing back-to-back fours before thumping one into the stands for six.
Not to be outdone, Malan put away three consecutive fours off Santner and some more tidy running brought England to 61 for one at the end of the powerplay.
Sodhi struck in the seventh over when Jacks appeared to accidentally clip the ball with his bat twice allowing Allen to comfortably catch, but Malan instantly responded by belting a huge six over an outstretched Chapman at deep midwicket.
Not letting his omission from the provisional 50-over World Cup squad phase him, Brook dispatched two successive Sodhi deliveries into the stands and just after England reached the 100-run mark, Malan fired another ball into the crowd to bring up his 50.
Ferguson soon ended Malan’s heavy hitting with Mitchell catching the batter at mid-on, but Brook continued to put runs on the board before Livingstone put the game to bed in style with a huge six with 36 balls to spare.
Jake Fraser-McGurk top-scored with 84 – hitting 50 off just 15 balls – while Tristan Stubbs (48) and Shai Hope (41) also chipped in with important contributions as the Capitals set a target of 258.
Mukesh Kumar (3/59) and Rasikh Salam (3/34) did their best to halt Mumbai’s revival, but they turned up the pressure to require 25 runs from the final over.
However, despite Luke Wood and Piyush Chawla’s best efforts, Delhi held out for a second successive win.
Data debrief
Wood almost made amends after conceding 68 runs during the opening innings – the joint-most in the IPL this season, matching Reece Topley’s tally against Sunrisers Hyderabad.
Tilak Varma led Mumbai’s attempted revival with 63 for his sixth half-century in the IPL, though they have all come in defeats
Wood has been all over the globe since finishing runner-up with the Lightning in last year’s competition, making his England debut in a historic tour of Pakistan, travelling to Australia as a reserve for the triumphant T20 World Cup and picking up franchise deals in the Big Bash, the UAE’s IL20 league and the Bangladesh Premier League.
It has been the most lucrative and demanding period of the 27-year-old’s career, with new experiences, new team-mates and new responsibilities to bear.
But on Saturday he will be lining up for the Red Rose against Derbyshire in Edgbaston’s ‘Blast Off’, a double-headed curtain-raiser for the white-ball season that also sees hosts Birmingham Bears take on Yorkshire.
“I’ve certainly been claiming a lot air miles. I’ve been busy, but I’m back home,” he told the PA news agency with a smile of satisfaction.
“Whenever I come back to play for Lancashire, that’s my pride and joy. This is where I earned those opportunities in the first place. After four busy months away, it’s back to reality. Being here, this is my job.
“But I’ve enjoyed that franchise circuit so much, it can only grow your game as a player. You talk about the captains, the coaches, the different ideas…you’re learning all the time.
“My international career might be limited so far but I’ve been able to play against that calibre of player regularly and I feel my game has come on so much.
“Being an overseas player is a big thing. The expectations are on you and the drive now is the same as when I’m in that overseas role. I pride myself on meeting the same expectations.”
Wood admits Lancashire are a side with some frustrations to work out, be it from last season’s finals day where they gave up a winning position to lose the title to Hampshire or this year’s record of five consecutive draws in the LV= Insurance County Championship.
“You can see as a club we are hungry for a win,” he added.
“There aren’t too many draws in T20 cricket thankfully and we want to get the ball rolling. Coming second last year has almost given us a bigger drive for the Blast because finishing runner-up feels the same as losing.
“It’s always disappointing to lose a final, but it gives you a bit of extra motivation. We felt like we were cruising for a long time but you know it’s never over in T20. Next time is for us, I hope.”
Derbyshire’s head coach Mickey Arthur is another man with unfinished business in the competition.
His side enjoyed a strong run in the North Group of last year’s Blast, but dropped the ball in their quarter-final against Somerset as they were rolled over for 74 chasing 266.
“We did fall off the rails in the quarter-final but we’re better for that experience,” Arthur told PA.
“It did leave a bad taste, but it’s easy to forget we won nine games in a row against some big teams. The guys have learned. You can’t go to a supermarket and and buy experience, you’ve got to go through it.
“Our recruitment has been good too and I really think we’ve got a side who can shake up a couple of teams.”
The Yorkshire batter struck a half-century in the seven-wicket victory over New Zealand in the first T20 on Wednesday.
Malan made 54 off 42 balls as England chased 140 with 36 deliveries to spare after pacemen Brydon Carse and Luke Wood took three wickets apiece to restrict the tourists to 139 for nine at Chester-le-Street.
With England having so much strength in depth these days, Malan was delighted to be in his country’s white-ball plans.
He said: “(It was) definitely relief, you look at the amount of depth we’ve got in English cricket, especially having sacrificed so many tournaments over the last couple of years to get in this World Cup squad, to get the call was extremely satisfying.
“I know there are people who’ve missed out and I have so much sympathy for them. From a personal point of view I was exceptionally pleased to get that call because I felt I’ve worked really hard to get in that squad.
“Every opportunity I’ve been given in 50 overs in my last four or five series I’ve gone and had to score the runs, doing it the tough way to get in there.
“Especially the top three, I know people compare me to Brooky (Harry Brook), but I bat top three and he bats four, five, six, so I don’t know where that comparison comes from.
“To be able to push for a place in that World Cup squad and get the call was extremely satisfying.”
England’s white-ball preparations for the World Cup continue after the New Zealand series with three ODIs against Ireland in September before flying out to India for the 50-over tournament which begins in October.
After his omission from the provisional World Cup squad, Harry Brook showed off his heavy hitting at the Riverside with 43 not out from 27 balls and Malan is determined to keep scoring in order to claim his spot for India.
“I think you always have to score runs when you play international cricket, especially when you have the depth we do here,” he added.
“It’s a provisional squad but from my understanding it’s up to us to score runs to stay in it.
“I think it would be tough, two weeks before we are flying, especially with people potentially resting for the Ireland series, to suddenly lose their place.
“But that is cricket and that’s the way life goes. Nothing is ever guaranteed until you stand on that plane.
“I try my best to score runs- that’s what I’m picked for, to score runs and win games. I am not there to please anyone, I’m there to score runs for Jos (Buttler) and (Matthew) Motty and contribute to wins.
“I feel like I have done that consistently over the last five or six years, whatever it is in white-ball cricket.”
