NANCY Harman's unbeaten 26 got Southern Vipers over the line in a tight seven-wicket victory over Lancashire Thunder to make it three wins in a row for the holders.

Harman, who was making her first appearance of the season, came to the crease with the Vipers wobbling on 136 for six needing 207 – and behind the DLS with rain about.

But she beat her previous best of 23 not out to guide her side to victory and continue Vipers’ unbeaten record against Thunder.

The result means Southern Vipers are now second in the table in the Rachael Heyhoe Flint trophy.

Earlier, Sunrisers batter Seren Smale beat her previous best of 94 before being run out on 99.

Thunder could only muster 206 for 9 from their 50 overs with Vipers' Linsey Smith picking up three wickets.

With rain around, Vipers tried to match the DLS target with captain Georgia Adams crashing a series of straight boundaries.

Adams and Georgia Elwiss put Vipers comfortably ahead of the rate with a partnership full of quality but two quick wickets put things back in the balance.

Adams reached her 50 in 62 balls but then top-edged Naomi Dattani behind to swing the momentum back to the visitors.

But Rhianna Southby, Harman, and Alice Monaghan scored the last 72 runs to guide Vipers to victory with 39 balls to spare.

Speaking after the win, Southern Vipers all-rounder Nancy Harman said: "I just wanted to take my opportunity. We've put together some good 50-over cricket.

"If anything, that first loss (to South East Stars) was such a tight game and such a good contest that I think it almost amped us up to come and play the next three.

"We love playing here at Wormsley. We've had some really good performances from different members of the team.

"It's certainly been a better start than we had to the RHF last year. But let's hope we can continue it all the way through."

The Southern Vipers will be looking to make it four wins from five when they play Western Storm on Saturday, May 4.
