A Chris Lynn masterclass has led Northamptonshire to a 31-run victory over Durham in the Vitality Blast.
In his first home game for the Steelbacks in the competition, the Australian took an instant liking to Wantage Road as he cracked 83 from just 46 balls.
The Queenslander enjoyed a strike rate of 180, his innings including eight sixes and four boundaries.
He shared in a 149-run partnership with Ben Curran as the hosts reached 4-223.
It proved more than enough as a shell-shocked Durham were bowled out for 192 after 18.5 overs.
The Birmingham Bears survived a late Derbyshire surge to win an exciting game at Derby by three runs.
It was a match to forget for Derby’s newly signed Australian allrounder Hayden Kerr, who went for 55 in his four overs and made just eight with the bat after being run out.
The Bears smashed 89 off the last five overs to reach 200 for the second night running but the Falcons fought back and came close to pulling off what would have been their biggest T20 run chase.
Brooke Guest’s 54 from 34 balls almost swung the game in a dramatic finale but Craig Miles kept his nerve as the Falcons finished on 8-197.
Harry Brook fell to the final ball of the game as rivals Lancashire and Yorkshire played out a thriller at Old Trafford.
Yorkshire, chasing 184 to win a first Blast Roses game away from home since 2014, looked on course after Brook (72) and Tom Kohler-Cadmore (67) shared 115 for the fourth wicket.
But fast bowler Richard Gleeson trapped the in-form Brook, who has been called into the England Test squad for the first time, lbw with only one run needed.
In other matches, Surrey defeated Glamorgan by four wickets with a ball to spare while Nottinghamshire beat Worcestershire by four wickets at Trent Bridge.
Gloucestershire beat Sussex by 41 runs while Middlesex registered a 10-run win over Hampshire.
Essex claimed a four-wicket victory over Kent with two balls to spare in their derby at Canterbury, with the visitors reaching 6-188 in reply to Kent’s 4-184.
