T20 holders Northants beaten
Defending champions Northamptonshire suffered their first defeat of this season's NatWest T20 Blast after losing to Worcestershire on Friday.
Newcomer Richard Oliver smashed 77 off 43 while his opening partner Moeen Ali struck 41 as Worcestershire chased down Northamptonshire's 134 for seven with almost six overs in hand at New Road.
England international Moeen had earlier claimed two for 23 to help peg back Northamptonshire, who had looked on for a big score as David Willey, the star of last season's final mauling of Surrey, clubbed four sixes in a rapid 34 at the top of the order.
The result ends the last unbeaten record in the North Division with Northamptonshire having picked up five points from their opening three games.
In the same division Yorkshire were celebrating their first win as local youngster Alex Lees upstaged Australia star Aaron Finch on his debut in the Vikings' eight-wicket win over Derbyshire.
Lees, 21, struck nine fours in his unbeaten 61 while Jonny Bairstow added 29 not out off 16 balls as Yorkshire passed Derbyshire's 127 for six with plenty to spare at Headingley.
Finch, the top-ranked T20 batsman in international cricket, struck his third ball for six but he could only make 19 before being caught and bowled by compatriot Marcus North and it was down to Lees to lead Yorkshire home.
North Division pacesetters Lancashire made it four wins from five with a 15-run victory in a low-scoring game against Warwickshire at Old Trafford.
Lancs, who could have former England captain Andrew Flintoff back in their line-up this time next week, looked in some trouble after being dismissed for 126.
However, a superb bowling performance, led by paceman Junaid Khan (four for 12), helped Lancs skittle winless Warwickshire for 111 in reply.
Solid bowling also helped Durham defend a modest total against highly-fancied Nottinghamshire as they recorded a three-run win at Trent Bridge.
Durham were limited to 132 for eight batting first but Nottinghamshire could only make 129 for seven in reply, Chris Rushworth taking three for 19 including the wicket of England dangerman Alex Hales for five.
In the South Division, Hampshire won the battle of the top two in emphatic fashion with a crushing eight-wicket win over previously-unbeaten Essex at The Rose Bowl.
Chasing Essex's 145 for five, leaders Hampshire stormed home with 16 balls to spare thanks to unbeaten half-centuries from James Vince (57) and Owais Shah (50).
The defeats for Essex, Warwickshire and Northamptonshire on Friday night means the only remaining unbeaten team in this season's competition are Kent, who defeated Gloucestershire by 21 runs at Canterbury.
After being set a victory target of 137 by their hosts, Gloucestershire fell well short on 115 for nine as Kent spinner Adam Riley (four for 22) picked up four of the visiting side's top five.
On a night where big scores were in relatively short supply across the country, there were runs galore at Cardiff where Glamorgan successfully chased down Sussex 178 for seven for the loss of just five wickets.
Chris Cooke led the way for the Welsh county with an unbeaten 65 off 31 deliveries, including 11 fours and a six, while former South Africa batman Jacques Rudolph added 50 at the top of the order.
In the evening's other game, Middlesex slumped to a fifth successive loss after going down by six wickets to Surrey at the Oval.
Opener Dawid Malan's patient 48 not out helped Middlesex limp to 117 for seven, and Surrey knocked those runs off with eight balls to spare as overseas star Hashim Amla top-scored with 39.
