Nottinghamshire 155 for 3 (Clarke 45) beat Northamptonshire 152 for 8 (Christian 3-32) by seven wickets
Joe Clarke rediscovered some of his best form to help Notts Outlaws open their account with a first victory in this season's Vitality Blast competition. Notts had already been defeated by Worcestershire Rapids and suffered a washout in their other match but had the better of their Trent Bridge encounter with Northants Steelbacks, eventually triumphing by seven wickets with 11 balls to spare.
Clarke, who has had a lean season with the bat, scored 45 from only 34 balls and put on 79 for the first wicket with Alex Hales as Notts chased down a victory target of 153 to maintain a lengthy winning streak against the Steelbacks. Hales followed up his 52 against the Rapids with a stylish 33.
Notts had the run chase in control right from the start, although Pakistan international Faheem Ashraf did begin with a maiden to Clarke. Hales helped both Nathan Buck and Dwaine Pretorius over the ropes in the initial overs and Clarke then heaved Ashraf over wide long-on to end the Powerplay on 60 without loss.
A crowd of 13,691 - a Trent Bridge record for a midweek T20 match - lapped it up as the home side found the boundary repeatedly.
Clarke was eventually dismissed by Nathan Buck and Hales followed, falling to former team-mate Graeme White but the onslaught continued. Ben Duckett, playing against his former side, scored 26, effectively setting the contest with two sixes off Pretorius in the 15th over.
Dan Christian, the Outlaws' captain, enjoyed a fine match and finished with an unbeaten 22, with Tom Moores bludgeoning the ball over the ropes for the winning runs.
Earlier, the Steelbacks made 152 for 8 after winning the toss and opting to bat. They limped their way to 39 for 2 from the opening six overs, with Matt Carter removing the dangerous Adam Rossington with the sixth ball of the match.
Josh Cobb hit both Carter and Samit Patel for sixes but was then completely bamboozled by Harry Gurney's slower delivery and could only balloon the ball up to cover. Christian couldn't have had a better start with the ball, bowling Rob Keogh with his first delivery and having Matt Coles caught behind with his fifth.
The Steelbacks' new overseas pairing of Pretorius and Ashraf mounted a counter-attack, adding 36 in just three overs together but neither could see out the innings. Ashraf was unlucky, having plundered 24 from only 14 balls he was caught by a diving Gurney at short third man, giving Christina his third wicket.
Pretorius fell to Jake Ball for 34, leaving White to muscle some useful runs in the closing couple of overs, hitting two sixes in his unbeaten 24.
On a decent surface, with a fast outfield, the eventual total appeared light and so it proved, extending Northants' unwanted record of never having beaten Notts in the group stages.
