This was one of the games of the summer.
The Diamonds won a Charlotte Edwards Cup T20 fixture by one-wicket against Western Storm at Taunton immediately before the break for the Hundred in early July.
All-rounders Alex MacDonald and Jenny Gunn were the heroes of a game which saw both sides put on an exhibition in the field but struggle significantly with the bat.
Chasing only 107, the Diamonds fell from 33-1 to require 10 off the last over with only one wicket in hand.
Step forward Gunn, who was batting with a fractured finger. Her 27 not out included two fours down the ground off Alex Griffiths in the final over with the winning hit sailing over mid-on’s head.
MacDonald’s canny seamers had earlier, impressively, secured her career best figures of 4-17. She ousted Katie George and Griffiths in the 11th over of the home innings after they had been inserted.
Linsey Smith also took the new ball and claimed an excellent 2-15 from her four overs as Storm finished on 106-9.
Sarah Taylor claimed two catches and a stumping in her final appearance of a short-term spell in blue.
The first of them was a stunning one-handed diving catch to get rid of Sophie Luff off Phoebe Graham’s bowling.
Despite the early loss of Hollie Armitage, the Diamonds were in a healthy state at 33-1 in the fifth over. But things unravelled as they lost eight wickets for 66 to put them on the back foot.
At 96-9 after 18.5 overs, you would have had the Storm down as favourites. But enter Gunn, who expertly quelled any nerves and secured a second win in three group games.
