Tom Curran says England’s lack of runs in the first one-day international with South Africa cost them the match.
England scored just 258 for eight from their 50 overs with early wickets causing a lot of damage.
The hosts eased to a seven-wicket victory with 14 balls to spare but never looked in any danger.
This is something they will be looking to rectify in the second match of the three-game series, with commentary live on talkSPORT 2.
Curran told talkSPORT: “You can pick parts of the game apart and analyse what went wrong but at the end of the day we didn’t get enough runs.
“Trying to defend that always looks worse than it is. Simply we didn’t get enough runs.
“It happens. We lost the openers and I think that run out was a huge changing point in the game. That goes for four and Rooty (Joe Root) and Morgs (Eoin Morgan) go on to bat for another 15 or 20 overs and it is a completely different game.
“That run out changed the momentum of the game and we had to rebuild. When you go four or five down early it does become hard.
“I thought we did really well to get up to a defendable score of 258, we have defended totals like that before.
“We did well to get that and at the end of the day they came out and played pretty well. They broke the back of the chase and yeah, 1-0 down and two to go.”
The England all-rounder, who scored 15 not out and ended up 0-38 from seven overs with the ball, also defended their tactics in the South Africa innings.
He said: “Were we supposed to keep every fielder in then do you think? We got the cover and the point in saving one. Mid-wicket saving one. There’s only so tight you can get before they are not saving one and not saving four. We tried and simply didn’t have enough runs.
“I don’t know if it got a lot better but I think it definitely got a little bit quicker. The slower balls weren’t gripping as much and when you are chasing a score like that you can dictate the tempo of the chase.
“You are getting ones and twos off the bowlers best balls and inevitably we have to try and take wickets and you get the odd boundary ball.”
Jofra Archer has been ruled out for three months due to a stress fracture in his elbow and will miss the Sri Lanka series as well as the Indian Premier League.
That is just part of being a modern cricketer and injuries sometimes cannot be helped, according to Curran.
He added: “Not ideal for Jof (Archer) and the teams he is a part of but that’s sport isn’t it? He’s had a good run now and hopefully he will come back fitter, better and stronger.
“Getting injured is just part of being a fast bowler nowadays.”
