New Zealand Devine slams fastest century in women's T20 cricket

New Zealand captain Sophie Devine smashed the fastest hundred in women's Twenty20 cricket on Thursday, reaching the milestone in just 36 balls in the domestic Super Smash competition.

Devine, 31, hit nine sixes and nine fours in her innings of 108 not out as her Wellington Blaze side beat the Otago Sparks by 10 wickets.

The all-rounder broke the previous record that had stood since 2010 -- a 38-ball hundred from West Indian Deandra Dottin.

Devine said she had felt nervous coming back after spending 14 days in isolation following her return from Australia.

"Whenever you have a bit of an extended break away from the game, you get nervous about (whether) you can come back into it," she told Spark Sport.

"So it was just (nice) to spend some time in the middle and get a few out of the screws.

"Sometimes I can get a little bit carried away ... and I get a bit over eager and play some rash shots so it was nice to stick to some decent cricket shots today and finish the job."

One of Devine's sixes grazed the cheek of a girl who was watching from the grass bank at the University Oval in Dunedin.

After the match, Devine went to check on the girl, who had an ice pack against her face but appeared to have avoided any serious injury.

A video posted on New Zealand women's cricket team's Twitter account showed Devine posing for a photo with the girl.
