Yorkshire lost the toss and were invited to bat first in the first of two 2nd XI T20s in Derbyshire this afternoon.
Bilal Anjum and Alex Lees gave Yorkshire a good start, followed by Jonathan Tattersall and, at 73/1 in the tenth over, a total of 160+ looked on the cards.
But wickets then started to fall regularly and, apart from a hard-hit 32 by Matthew Waite, no-one could put together a meaningful contribution from lower down the order and Yorkshire ended up 158 all out with four deliveries unused.
But then the bowlers and fielders put on a splendid display to defend the total. James Wainman returned 4/21 and Jack Shutt bettered that with 4/12, both career-best figures in this format.
Derbyshire succumbed for 136 (from 128/5) and Yorkshire were home by 22 runs for their sixth win in this format in 2017.
Yorkshire lost the toss and had to field first in the second of two 2nd XI T20s in Derbyshire this afternoon.
The bowlers and fielders simply took up where they had left off in Match 1.
Derbyshire had crawled to 75/5 in 15 overs when torrential rain lashed the ground. Matt Fisher had two wickets and there was one for Shutt and one for Wainman.
The fifth wicket fell to a splendid piece of fielding by Jordan Thompson, whose direct throw ran out Harvey Hosein. Thompson then also took a splendid catch, running away from the wicket with the ball coming over his shoulder. He called for the catch and securely pouched the effort.
When play was finally able to resume, the Derbyshire innings had been declared closed and Yorkshire had 11 overs in which to score 66 to win.
They achieved this target with ease as Ben Birkhead (37*) and Jonathan Tattersall (23*) added an unbroken partnership of 61 for the second wicket to complete a double and the full four points.
Yorkshire`s record in this format is now P10 W7 L2 Aban 1 (15 pts) and puts us top of the Northern group with Lancashire to play at Blackpool on Wednesday.
