A half-century from Lauren Winfield-Hill took Oval Invincibles to a crucial win against London Spirit in front of 14,721 fans in The Hundred at The Kia Oval.
Chasing 120, Invincibles captain Winfield-Hill made 61 from 40 balls, her first half-century this season, and combined effectively with Marizanne Kapp to make light work of a chase that could have been far more taxing.
That Invincibles had anything to chase was down to the first-innings heroics of Indian all-rounder Deepti Sharma, who guided the visitors to a total of 120-8 from the perilous position of 47-7.

Sharma and Eva Gray rebuilt with a record eight-wicket partnership after Invincibles bowlers took a wicket apiece to get ahead of the game early on - Kapp winning the battle of overseas superstars with a third-ball dismissal of Meg Lanning.
The game was in the balance at the interval but Winfield-Hill batted intelligently throughout, nullifying the threat of Spirit's trio of spinners by manipulating the field and accessing behind square with ease.
Chances were few and far between, though Spirit could have sent Winfield-Hill on her way had they opted to review a tight lbw call that went against the bowler Dani Gibson.
Kapp came in after birthday girl Alice Capsey was bowled ramping, and added some impetus to the foundations laid by Winfield-Hill to see the chase ticked off with nine balls to go.
Invincibles' win confirmed Manchester Originals' tournament is over, but more importantly for the home side it leaves them in control of their own destiny with one game to go ahead of The Hundred Eliminator and The Hundred Final.
For London Spirit, also with one game to play, they now need to win their last game and hope other results go their way to secure a place in the top three.
Player of the match- Lauren Winfield-Hill
"It's a great feeling. I was due so it's really nice to contribute, especially at the business end. I'm really pleased to get another good performance and another win.
"There was a little bit of hold in the wicket. There wasn't a lot of turn but it just seemed to hold and there was a little bit of bounce. To be honest, I don't think I've ever played that many reverse sweeps in my whole career but it was just one of those things where it was working and I just kept doing the things that were working.
"I was really determined to put in a good performance today, and to be there at the end with Kappy is a really nice feeling."
Mooney makes mark with sensational 99 as Originals defeat Superchargers
Beth Mooney ended unbeaten on 99, the highest individual score in The Hundred this year, to lead Manchester Originals to 151-3 and a rare win over rivals Northern Superchargers in The Hundred.
The Australian left-hander was imperious and classy throughout, finding the gaps at will and demonstrating the kind of form that sees her ranked as the No.1 batter in Women's IT20 cricket.
She was to finish up stuck on 99, agonisingly short of the women's competition's second-ever hundred, when Sophie Ecclestone was run out seeking an improbable two from the final ball of the innings.
Fortunately for Mooney, despite missing out on a personal landmark, her fine innings was to come in a winning cause despite fellow Aussie Phoebe Litchfield causing a few butterflies with an impressive innings in riposte.
Litchfield made 45 from 29 but when she fell, bowled by a nicely executed slower ball by compatriot Kim Garth, the team in purple ran out of steam in pursuit of a big chase.
There was still time for Kathryn Bryce to claim a hat-trick, split over her final two sets, and to take 5-13 to give Originals a further personal landmark to celebrate on a day that came in vain for their hopes of progressing in the tournament.
Their victory did prevent Superchargers, their cross-Pennines rivals, from ascending to the top of the table and sees the top of the table in the women's competition further congested going into the final week.

"It was a lot of fun. I thought Laura Wolvaardt and I set the game up nicely at the top and obviously Kathyrn Bryce finished it beautifully getting five-fer there. A pretty good day out for the Originals.
"A little bit [of regret at not reaching 100]. But if you'd told me this morning I would have scored that many runs I would have taken it, and got the team in a winning position as well, which is most important.
"I did the best I could and didn't quite get over the line for that milestone but for me it's about trying to get the team into a winning position and I thought 150 was probably about par.
"We saw some of the batters in the Superchargers took the game to the sword a bit and could have taken it away from us pretty quickly, but I thought we were really composed and bowled beautifully."
