MEN'S T20 BLAST ROUNDUP: There were also wins for Northamptonshire, Birmingham Bears, Glamorgan, Surrey and Hampshire while Notts Outlaws defied a faulty floodlight to beat Derbyshire on DLS
New Road: Northamptonshire 190-5, Worcestershire 159 - Northamptonshire win by 31 runs
Northants' Ben Sanderson stole the show as he returned figures of 6 for 8 in a simply outstanding bowling display as Northants Steelbacks hurried to a 31-run win over Worcestershire Rapids in the Vitality Blast North Group.
Setting their opponents 191 to win, it was Ricardo Vasconcelos (59) who anchored the Steelbacks innings.
In reply, the hosts never got a foothold in the game, with plenty of batters making starts, but regular wickets hampered their pursuit of a competitive score.
Sanderson's exceptional evening was capped off with a hat-trick as a clinical Northants bowling performance secured them a fourth straight win.
Leicester: Leicestershire 193-8 v Durham 187-7 - Leicestershire Foxes won by six runs
Leicestershire Foxes picked up a third T20 Blast win in four matches to keep their place among the front-runners in the North Group, defeating Durham by six runs in a tight finish at the County Ground.
Ben Raine took 5 for 23 against his former team-mates, with four wickets in his final two overs, but the Foxes still posted 193 for 8, their highest Blast score against Durham after skipper Louis Kimber made 51 off 27 balls and Lewis Hill 47 off 30.
Graham Clark's 29 from 12 balls in the powerplay suggested Durham would make a fight of it, but after collapsing from 65 for 1 to 94 for 6, they looked out of the game, Tom Scriven taking 2 for 25.
Yet Kasey Aldridge (44 not out) and Will Rhodes (43) shared a 91-run partnership that took Durham into the last over needing 13 to win before ex-Durham bowler Matt Salisbury kept his nerve to concede just six.

Edgbaston: Yorkshire 164-7, Birmingham Bears 168-4 - Bears win by six wickets
Warwickshire Bears condemned Yorkshire to a third successive T20 Blast defeat as they handed them a six-wicket beating at Edgbaston.
The Bears registered their first win of the campaign after Yorkshire, put in, totalled 164 for 7, having lurched from 139 for 2 to 146 for 7 in 17 balls. Dawid Malan (69 not out) and James Wharton (39 off 23) set a solid foundation, but the middle and lower orders were scalped by the spinners as Danny Briggs, Jake Lintott and Moeen Ali each took two wickets.
Alex Davies (65) and Tom Latham (44) then added 103 for the first wicket, and though Matt Milnes (3 for 23) induced a wobble, the Bears reached 168 for 4 with six balls to spare.
Derby: Derbyshire 162-9, Notts Outlaws 120-3 - Notts Outlaws won by seven wickets (DLS Method)
A power cut could not deny Notts Outlaws victory over local rivals Derbyshire Falcons in an extraordinary T20 Blast North Group match at the Central Co-op County Ground.
Outlaws were 108 for 3, chasing the 162 for 9 set by Falcons, when the floodlights went out midway through the 13th over.
When power was restored, the visitors were set a revised target of 120, and they easily sealed victory by seven wickets under the DLS method.
Cardiff: Essex 183-8, Glamorgan 185-4 - Glamorgan win by six wickets
A magnificent Kiran Carlson 93 led Glamorgan back to winning ways against a winless Essex at Sophia Gardens.
The captain's knock was the catalyst in a successful chase of 184 and a six-wicket win after support from Will Smale with 43 as the opening pair set a strong platform for Carlson to continue throughout the innings.
Suffering their third defeat, Essex's strong total set the visitors in a strong position led by Michael Pepper's 30-ball 60 which included five sixes, his second half century already in this competition.

Canterbury: Surrey 193-7, Kent 151-9 - Surrey win by 42 runs
Surrey have thrashed the Kent Spitfires by 42 runs in the Vitality Blast at Canterbury.
Surrey posted 193 for 7, Ollie Pope giving them a platform with 53 before Laurie Evans assaulted the death overs, making an unbeaten 62 from just 26 balls.
England's Zak Crawley hit 45 but the Spitfires crashed from 109 for 2 to 118 for 8, losing six wickets in a cataclysmic 17-ball spell. Mitchell Santner took three for 28 and Kent eventually closed on 151 for 9. Grant Stewart had Kent's best bowling figures with 3 for 27.
Utilita Bowl: Gloucestershire 119, Hampshire 121-3 - Hampshire win by seven wickets
John Turner led an outstanding Hampshire Hawks bowling performance to set up a third straight victory to start their Men's Vitality Blast campaign.
Turner picked up three wickets before Chris Wood, Scott Currie and Benny Howell all snaffled two at under five runs an over to hold defending champions Gloucestershire to 119.
Opener Toby Albert, on the back of 54 and 28 not out, dominated the chase with a personal best 73 as Hawks strode to the winning line with 30 balls to spare.
