Sussex duo Holly Colvin (left) and Sarah Taylor celebrate

Sussex teenager Holly Colvin inspired England's women to a commanding 121-run win in the opening match of the one-day series with South Africa at Canterbury.

The 18-year-old left-arm spinner took 3-17 from her 10 overs as the South Africans were bowled out for 133 in the 42nd over at the St Lawrence Ground.

Sarah Taylor and Claire Taylor both struck fifties as England posted 254-6.

The senior Taylor recorded seven fours in a 79-ball 83 before she was run out, but several players also contributed.

Sarah Taylor, another Sussex teenager, opened the innings and shared 99 with Caroline Atkins, before both were caught and bowled in quick succession.

Skipper Charlotte Edwards shared a century stand with the senior Taylor before she also fell victim to a return catch.

Only three South Africans reached double figures, with Colvin soon taking control and she was well supported by Isa Guha and Edwards, who claimed two wickets each.

"I'm really happy with the convincing start to the series." Edwards said afterwards.

"It's brilliant to be playing international cricket again after our taster against the West Indies in July.

"I was pleased to be able to make a major contribution to the game today and spend some time in the middle," added Claire Taylor, who was named Player of the Match.
