T20 Blast: Bears & Blaze reach women’s Finals Day, Surrey and Durham win

At Old Trafford, England batter Lamb continued her good form for Lancashire, hitting a six and eight fours in her 48-ball innings before being caught at mid-wicket off Sophia Turner (3-27). But no-one else reached 20 as they totalled 148-7.

Suzi Bates set Durham’s run-chase in motion with 33 off 22 balls before she was caught at short third man as she tried to swing Tara Norris into the leg-side, leaving her 10 runs short of 400 in the competition.

A spell of 3-24 by Australian spinner Alana King kept Lancashire in the game, but 43 off 23 balls by Bess Heath pushed Durham on towards their target. Although she was bowled by Darcey Carter in a slump from 139-5 to 143-8, the visitors squeezed past the target with four balls in hand.

Surrey did not have Danni Wyatt-Hodge in their side at The Oval and found themselves on 68-4 in the ninth over, with Alice Capsey among those dismissed, caught behind for 27 as she tried to sweep Chloe Skelton (2-20).

But Monaghan hit four sixes and added 89 with Emma Jones (34), having missed part of the season with a broken finger, as the home side set Somerset – who had won only one of their 11 previous matches – a tough target.

It was a task that proved beyond them as wickets fell regularly throughout their reply and spinner Dani Gregory returned figures of 4-13 as she bowled Erin Vukovic to end Somerset’s innings on 107, with 15 balls unused.
