Nottinghamshire maintained the last remaining perfect record in the Royal London One-Day Cup following a four-wicket win over Yorkshire at a sold-out Trent Bridge.
The Outlaws had passed 400 in their previous two home games of the tournament but it was their bowlers who took centre stage in front of almost 15,000 spectators to bowl out the Vikings for 213.
Jake Ball was the pick of the bowlers with three for 32 before the home side's batsmen made light work of the modest total with captain Steven Mullaney's unbeaten 54 guiding them home with 15.3 overs to spare.
The Outlaws' fifth successive win leaves them a game clear at the top of the North Group with Durham their closest challengers after Cameron Bancroft's team secured a three-wicket home win over Derbyshire.
Alex Lees hit a third successive half-century and Michael Richardson's unbeaten 72 ensured the Durham win after Derbyshire where restricted to 254 for eight.
Champions Hampshire suffered a first defeat as experienced Essex duo Ryan Ten Doeschate and Ravi Bopara did the damage with the bat, scoring 89 apiece, in a 111-run win at the CloudFM County Ground in Chelmsford.
Bopara then claimed three wickets, along with four from Matt Coles, as Hampshire never came close to reeling in the 339 for six target.
Sam Hain breathed life into Warwickshire's campaign with a superb 161 from 140 balls as the Bears secured their first win of the competition by 34 runs against Worcestershire.
Hain's highest List A score included 10 fours and six sixes as the Bears piled up 315 for five – their highest 50-over total against the Rapids – before captain Jeetan Patel's three wickets engineered a collapse of seven for 59.
Wayne Parnell crashed 75 from 56 balls from number nine to keep the Bears sweating before he was last man out with 16 balls remaining.
Gloucestershire inflicted Somerset's first defeat with a last-over win by four wickets at Bristol.
Benny Howell's three wickets restricted Somerset to 241 for nine and a tense chase was completed thanks to an unbeaten 49-run stand, from 29 balls, between Jack Taylor and Ryan Higgins.
Glamorgan were indebted to a Billy Root century and an all-round Marchant de Lange display as they claimed a first win by 64 runs against Surrey.
Root hit an unbeaten 113 and combined in an unbroken stand of the same value with De Lange (58 not out), before the South African ripped through the Surrey order with five for 61.
Saqib Mahmood became the first Lancashire bowler to claim five wickets in back-to-back List A matches in a nine-wicket win against Leicestershire at Emirates Old Trafford.
Leicestershire were skittled for 80, which the hosts knocked off in 19 overs to claim a third successive win.
