Dottin’s unbeaten 37-ball 67 propelled Manchester Originals’ to 156-2 from their 100 balls.
Dottin, who recently retired from international cricket and Sophie Ecclestone, who made an unbeaten 36, were mainly responsible for MO’s winning total after they lost opener, Emma Lamb, for 35 and Lizelle Lee for just three.
Alex Hartley had the best figures for Welsh Fire with 1-17 from 20 balls while Annabel Sutherland took 1-33 from her 20-ball allotment.
Needing 157, Welsh Fire made a fist of it, scoring 145-3, thanks mainly to the efforts of openers Tammy Beaumont who scored 45 from 42 balls with five fours and Hayley Matthews, who smashed 69 from 41 balls, blazing 12 fours along the way.
Dottin dismissed Racheal Haynes for 11 and Sutherland for 0 as the Welsh Fire chase fizzled, to return figures of 2-21 from 15 balls.
Ecclestone who took the prized wicket of Matthews had figures of 1-27 from her 20 balls.
Dottin’s 30-ball 68 that included five fours and six sixes helped MO to 160-3 from the hundred balls. Opener Lizelle Lee's 27-ball 40 and Sophie Ecclestone’s 17-ball 24 were significant contributions to what seemed like a winning score.
However, Northern Superchargers recovered from 106-3 with 24 balls remaining to snatch victory at the death thanks to a whirlwind knock from Laura Wolvaardt, who smashed an unbeaten 90 from just 49 balls.
The South African batter clubbed 13 fours and two sixes to propel her side to what seemed like an unlikely victory.
Alyssa Healy contributed 28 from 18 balls and Hollie Armitage 24 from 20 also made useful contributions.
Dottin proved a tad expensive with the ball conceding 34 runs from 19 balls.
Kate Cross 1-26 from 20 balls and Emma Lamb 1-23 from 15 were MO’s best bowlers.
The Originals, after being inserted by the Spirit, made 135-5 from their 100 balls thanks to 58 from Captain Phil Salt and 38 from Max Holden.
Pacers Richard Gleeson and Olly Stone took two wickets, each, for the Spirit while Andre Russell went wicketless while conceding only 14 from his 10 deliveries.
The Spirit then fell just short of their target, reaching 123-5 from their 100 balls.
Opener Keaton Jennings led the way with 61* off 50 balls while Hetmyer, batting at five, made 44 off 35 balls including three fours and a six.
Fazalhaq Farooqi took 3-24 from 20 balls for the Originals.
This result means the Spirit, like their opponents, have no chance to advance to the knockout phase of the tournament.
This was the Originals’ first win in six games while the Spirit have a similar record and are one spot above them in the eight-team table.
Nicholas Pooran delivered a masterclass in power-hitting as he hammered an unbeaten 66 off just 33 balls to lead Northern Superchargers to a thrilling seven-wicket victory over Manchester Originals in The Hundred on Sunday.
Pooran's explosive innings, highlighted by eight towering sixes, turned the tide in a match that seemed to be slipping away from the Superchargers at various points.
The Superchargers, chasing 153 for victory, found themselves in a precarious position at 29 for 2, needing over 100 runs with more than half the innings gone. The situation was made even more daunting by a suspected hamstring injury to Ben Stokes which forced him to leave the field.
Despite the early setbacks, Pooran, who has been in scintillating form throughout the tournament, stepped up to the challenge. He walked in with everything to do and proceeded to unleash a brutal assault on the Originals' bowlers. Alongside Harry Brook, who contributed a crucial 43, and Adam Hose, Pooran methodically dismantled the opposition's attack, ensuring that the Superchargers stayed alive in the competition.
The Originals, led by Phil Salt's blistering 61, had earlier posted 152 for 7, riding on the momentum of the highest-ever Powerplay score in the competition. However, the Superchargers' spinners, led by Mitchell Santner with figures of 3 for 24, pulled things back, restricting the Originals to a manageable total.
The chase, though steep, was made to look routine by Pooran's brilliance. The West Indian powerhouse demonstrated his ability to take the game away from the opposition with clean hitting and smart rotation of strike. Brook and Hose provided valuable support, ensuring that the Superchargers crossed the line with 62 balls to spare.
Reflecting on his match-winning knock, Pooran said, "It's definitely one of my better innings, knowing the situation of the game. Walking into bat with 100+ runs to get, and in this format, it creeps up on you very fast, but I was really happy that I could contribute and be there to the end."
He added, "You don't win tournaments with just one person contributing. It's really good when your teammates can contribute, and hopefully, we can go to our game on Tuesday and fight. If we lost the game today, we'd be out of the tournament. I'm happy that I could be there to the end, contribute, get the win for the team, and hopefully, the result will be the same again on Tuesday."
The victory keeps the Superchargers' hopes alive as they prepare to face London Spirit in a must-win game at Headingley on Tuesday.
Russell, 34, smashed an unbeaten 23-ball 64 that included six fours and five sixes in Manchester Originals' mammoth score of 188-2. He was given the perfect platform after openers Joss Buttler (68) and Phil Salt (34) gave the side a solid start with a stand of 64.
Buttler clubbed three fours and five sixes in his 42-ball knock while Salt found the boundary ropes on four occasions and cleared it once is his innings that lasted 22 balls. However, while both knocks were impressive, they paled in comparison to the mayhem that Russell produced scoring at a rate of 278 per cent to drive Manchester to within 12 runs of the 200 mark.
Jake Lintott, who dismissed Salt was the best of the Brave bowlers with 1-28 from 20 balls while Michael Hogan took Buttler’s wicket to finish with 1-48 from his 20 ball allotment.
Faced with a daunting target, Southampton crumbled under the scoreboard pressure, capitulating to 120 all out.
Openers Quinton de Kock (21) and James Vince (20) gave them a good enough platform with an opening stand of 36 but Southampton Brave were simply unable to maintain the scoring rate of 1.88 runs per ball.
George Garton’s 25 from 14 balls and Ross Whiteley 21 from 12 attempted a short-lived late-order revival that would invariably come to nought.
Russell picked up the wicket of the dangerous Tim David, who made a run-a-ball 10 to finish with figures of 1-7 from five balls.
It was Paul Walter, though, who did the most damage with 3-20 from 15 balls. Mark Pattinson and Tristan Stubbs took two wickets each for the Manchester Originals.
For his heroic efforts with bat and ball, Russell was named Player of the Match.
