Hampshire Royals moved to the top of the Yorkshire Bank 40 Group B table after cruising to a nine-wicket victory against Scottish Saltires.
After the visitors' bowlers all contributed wickets in skittling their hosts for 136, James Vince hit an unbeaten 75 from 52 deliveries to help reach the target of the first ball of the 16th over.
With Durham Dynamos' clash with Essex Eagles an evening start, Hampshire put the pressure on with a dominant performance and their place at the summit was confirmed when the Eagles triumphed.
Jimmy Adams won the toss for the Royals and Scotland were soon in trouble having been asked to post a total.
Dimitri Mascarenhas struck with his first ball, trapping Freddie Coleman lbw for one.
The 35-year-old pounced again in his next over as he had Richie Berrington caught in the covers for nought by a diving Vince.
When Calum MacLeod was ousted by Sohail Tanvir in the seventh, the Saltires were 23 for three.
Hamish Gardiner and captain Preston Mommsen offered some resistance, putting on 37 for the fourth wicket.
Gardiner faced 61 balls and scored 29 - his side's highest in the match - before he was dismissed by Danny Briggs, who removed Moneeb Iqbal in his next over for figures of 2-35
Mommsen was run out for 21, reducing them to 64 for six and, after Majid Haq soon followed, it was left to Gordon Goudie and wicketkeeper Matthew Cross to try and salvage the innings.
The pair added 26 and 22 respectively, but Goudie ran out of partners and Chris Wood wrapped up the innings with the dismissal of Gordon Drummond from the final ball of the 40 overs.
Hampshire seemed in a hurry to wrap up victory, with Vince and Michael Carberry hitting 14 from the first over.
The assault continued with their opening stand reaching 50 inside seven overs.
Goudie's third set of six yielded three boundaries and Vince's half-century but Carberry was stumped five short of the same landmark after a stand of 98.
However, Vince found the ropes twice more off Haq in the next over and won the match with his 12th four as he and Adams took the Royals home with 149 balls to spare.
