Notts won the toss under blue skies with the sun beating down and duly invited their opponents to bat first. And thanks to a hard-hit 59 by Ryan Gibson (46 deliveries; 8 fours) and a bustling 25 from Jonathan Tattersall, Yorkshire totaled a very reasonable 154/8 in their 20 overs.
But then it rained and four overs were lost from Nottinghamshire`s allocation, leaving them 16 in which they needed 131 to win.
Yorkshire had reduced their opponents to 70/4 in the eleventh over, meaning Nottinghamshire needed another 61 from 31 deliveries but Brett Hutton (28* after having earlier taken 3/21) and an unbeaten 32 by Adam Tillcock added an unbroken fifth wicket stand of 52, meaning that Yorkshire had just enough breathing space to record their first T20 win of 2015 by just 8 runs, under Duckworth-Lewis.
Notts again won the toss and again, invited Yorkshire to bat first. This time, it was the Captain, Will Rhodes who led the way with an unbeaten 61, made from just 38 deliveries with six fours and one six, Dan Hodgson (44 with six fours) gave him excellent support.
Yorkshire`s total of 163/4 was very respectable and looked even better when Nottinghamhire lost opener Billy Root for just a single. But the visitors batting rallied superbly and 30 by Anuj Dal, followed by a third wicket partnership of 76 by Sam Wood and Will Gidman saw Nottinghashire well in control.
Yorkshire needed several more quick wickets but it was not to be and Gidman`s unbeaten 60 saw his side home by six wickets.
So honours ended even and Yorkshire move on to York CC, where Durham will be the visitors for two more T20s next Tuesday (26 May), beginning at 11.30 am.
