Second women's ODI, Lord's:
England 310-3 beat South Africa 85 by 225 runs
Atkins became the third England woman to hit a century at Lord's
Caroline Atkins and Sarah Taylor put on the highest stand in the history of women's international one-day cricket as England thrashed South Africa.
Openers Atkins (145) and Taylor (129) put on 268 as England piled up 310 from their 50 overs in the second one-dayer against the tourists at Lord's.
South Africa collapsed to 85 all out in reply to lose by 225 runs and go 2-0 down in the five-match series.
Katherine Brunt took 5-25 and Charlotte Edwards 2-10 as England coasted home.
It was a day of personal triumph for a number of England's players, with Lydia Greenway and Nicky Shaw both winning their 50th caps.
Atkins became just the third England woman to hit a century at Lord's as she smashed her previous best of 69.
She scored 145 from only 155 balls with 12 fours, while Taylor's knock of 129 came off 133 balls with nine fours and a six.
"It was an emotional moment when I got my hundred. I just jumped for joy and looked up at the dressing room to see all my team-mates clapping me. They looked thrilled. My family were here too which made it even more special," Atkins told ecb.co.uk.
"I did not bat that well in the first game at Canterbury and thought I might not get selected for the third game if I did not play well today.
"I backed myself and thought I would rather fail giving it a go than making another sluggish 30. Luckily it came off but I need to carry on with that approach."
Ashlyn Kilowan was the pick of the South African bowlers, taking 2-51 from her seven overs.
But the visitors were shot out as they endeavoured to put together some sort of reply, with only four players getting into double figures.
The next match between the sides is at Shenley on Monday.
