Charlotte Edwards was among the impressed observers as Kate Cross grabbed 4-51 in what she considers her one-day international debut.
Cross was selected for the first game of three, yet it was washed out after just three overs of West Indies bowling.
That meant the seamer was unable to make a contribution in her first appearance, although she more than made up for it second time round.
Cross’ efforts ensured the Windies were dismissed for 126, with England overhauling a simple target to ease to a seven-wicket victory.
Her skipper Edwards said: “We wanted to come out really positive and I was really proud of the way the girls did that, especially Kate – who was bowling for the first time in ODIs.
“To put in that kind of performance in her first game is fantastic. She has impressed us throughout the whole trip.
“This trip was about us giving our younger girls an opportunity and you just hope they are going to take it.
“She has done that with both hands, which is fantastic. Hopefully we can have more of the same from her in the next game.”
Cross remarkably felt she could have bowled better, saying: “I was actually a little disappointed with my performance because I don’t think I bowled very consistently.”
She did take great heart from her figures, though, particularly after inclement weather ruined her debut.
Cross said: “It was very frustrating. I kind of classed tonight as my actual debut and I am just really pleased with the performance and result.
“I am not going to take anything away from the four wickets, which I was really pleased with. It is very overwhelming (to be voted man of the match) and I just really enjoyed it.”
England sealed their triumph as Sarah Taylor returned to form with a typically classy 55.
“She was back to her best today,” enthused Edwards. “She had a bit of a lean spell during the Twenty20s so it’s great to see her contributing again.”
