Rachael Heyhoe Flint Trophy: Jenny Gunn guides Northern Diamonds to narrow win over Lightning

Chasing 200, the Diamonds were three points short when they lost nine, but Gunn, who finished 41 not eliminated, won two singles before Katie Levick scored the winning run with two balls to spare.

Earlier, Tammy Beaumont, back from England duty, made 70 for Lightning.

There were wins for South East too Stars, Southern Vipers and Thunder.

The Diamonds' victory maintained their own perfect competitive start, but the record was in serious jeopardy as they slipped to 142-6 in response to the hosts' 199.

But Gunn found just enough support from the lower order, hitting four boundaries in a 77-ball inning to see his team go home house.

The Vipers top of the standings also had four wins in four games, but were pushed hard by the winless Sunrisers at the Ageas Bowl.
