New Zealand's big hitter Sophie Devine has left her Australian teammate Ellyse Perry awe-struck after blasting her way to one of the great white-ball innings in women's cricket.

The veteran Kiwi demonstrated all her famed power as she just missed out on the first-ever century in the new Women's Premier League, blitzing 99 off just 36 balls in Royal Challengers Bangalore's eight-wicket victory over Gujarat Giants on Saturday.

Earlier at the other WPL venue in Mumbai, the DY Patil Stadium, Alyssa Healy's UP Warriorz became the first team to beat the table-topping Mumbai Indians, with some robust hitting from her Australian compatriots Grace Harris and Tahlia McGrath helping them to a five-wicket win.

But it was as nothing compared to the late game at Brabourne Stadium, as the 33-year-old Devine smashed eight sixes with RCB making light work of the Giants' 4-188, reaching their target on 2-189 with 27 balls to spare.

Devine's power hitting was remarkable, as she clattered 84 in boundaries.

She was selfless too, getting caught at mid-off while still trying to boom one over the top in a bid to smash RCB to the quickest possible victory to help their net run-rate, rather than stroking a simple single that would have eased her to the first three-figure score in the league.

She crushed one six into the upper-tier of the stand and admitted afterwards that watching Australian all-rounder Ash Gardner crack a six and six fours in her 26-ball 41 for the Giants had been a bit of an education.

"It's been good to see how other batters go about it. So even just watching Ash bat, I learned a lot and just took out the best bits and applied it to how I wanted to bat," said Devine.

Unfortunately for Gardner, Devine also took a fancy to her off-spin, smashing her for 24 off her first over as the Aussie star ended up going for 48 off three.
