Broad has now taken 74 wickets from only 48 one-day internationals
England's Stuart Broad insists the team will retain their intensity after going 1-0 up in the one-day series with West Indies with a six-wicket win on Sunday.
Broad, whose 4-46 helped bowl out the tourists for 160 in Bristol, said: "It's a very happy changing room.
"It's a great start but we've got a massive game to win this series leading into a massive World Cup and obviously the Ashes. So we're very focused."
The final match of the series takes place at Edgbaston on Tuesday.
England skipper Andrew Strauss was pleased to record another victory and said: "It was very good performance, we took early wickets, we kept the pressure on and we made it hard work for them, both with the way we bowled and fielded.
"You back yourself to chase 160 more times than not so we're delighted with the performance, it adds to that momentum we got in the Test matches and we really want to win again on Tuesday and build even more momentum."
Strauss was full of praise for his opening bowler Broad, who struck twice in his opening two overs to dismiss Lendl Simmons and Ramnaresh Sarwan, then polished off the tail.
"He really thinks a lot about the game, he works hard in the nets with his variations and he likes the battle with the batsmen, trying to pit his wits against them and out-think them, and more times than not he does do that," he said.
"Both him and Jimmy (Anderson) as a combination are working really well together they are really revelling in leading the attack at the moment and long may that continue."
Counterpart Chris Gayle, by contrast, was far from happy and said: "We can't continue like this, someone will have to step up.
"There were some very soft dismissals. We should be able to bat out the 50 overs. We have to put up a better fight.
"We didn't analyse the situation properly. The batting display was disappointing.
Asked about his own dismissal, a wild swipe to end a cavalier 31, he said: "I'm disappointed with the way I got out. But sometimes when I do get in a defensive mood I get out as well.
"All is not lost. We can still actually square the series."
England all-rounder Paul Collingwood collected the man-of-the-match award after impressing with both bat and ball.
The Durham stalwart deputised as wicketkeeper for the injured Matt Prior in the recent second Test at the Riverside and quipped: "The wicketkeeping's got to go to bed, because the hands are too sore - so it's back to bowling.
"I managed to nip a few around, get a few through the gate - then get a few runs. So I'm feeling confident at the moment."
