Captain Eoin Morgan insisted the upbeat mood in the England camp was not seriously affected by the 13-run Duckworth-Lewis defeat to New Zealand.
The tourists levelled the five-match Royal London one-day international series with victory at The Oval.
Morgan led a brave bid to chase 398 for five on a superb batting surface, only for a rain interruption to make England’s task even harder.
He said at the post-match presentation, televised by Sky Sports: “It’s nice to contribute but a little bit disappointing it wasn’t to a win. The mood in the camp is quite high.
“It’s a great lesson and we did come so close. It’s not a bad day for us, a continuation of the way we want to play.
“The guys were willing to take 398 on, throw themselves at it and have the ability to throw themselves at it. It was very entertaining.
“I’m disappointed with our fielding and our execution with the ball - but the way we went about the chase, all credit goes to the guys - and to New Zealand.
“Up to the 35th/36th over, the run-rate didn’t really move and it wasn’t a problem for us. The challenge was trying to keep that consistency throughout. We know we bat deep and Adil Rashid and Liam Plunkett were outstanding tonight.
“Always, when you’re chasing a big score, the board is irrelevant - it’s the way in which you take the game to the opposition.”
The Duckworth-Lewis method did not help his team’s chances and Morgan continued: “Personally I think it will change over time as the game evolves.
“Potentially that could be looked at - but we were glad to get back out there and get a result. There’s nothing more frustrating than rain ending the game.”
