5:10pm - Notts and Glamorgan can be very happy indeed with their efforts. Both sides came into today with 100% records and maintained them in clinical fashion.
We will be back tomorrow with another live t20 blog featuring updates on games at Emirates Old Trafford, Taunton, New Road and Uxbridge.
5:05pm - RESULT! Glamorgan (132/2) beat Warwickshire Bears (126/8) by eight wickets at Rugby - Another veteran batsman, Murray Goodwin, finishes things off with a six at Rugby! Glamorgan, who now lead the Midlands/Wales/West Group, romp home with 14 deliveries to spare, skipper Wallace finishing unbeaten on 69 from 52.
5:02pm - RESULT! Notts Outlaws (156/2) beat Durham Dynamos (154/4) by eight wickets at the Emirates Durham ICG - David Hussey cracks a maximum off Stokes to seal a comprehensive Notts win with 27 balls unused. That was a terrific performance from the North Group leaders, who remain unbeaten.
5pm - Lumb is cruelly denied a century as leg-spinner Borthwick has him stumped for 96. Wicketkeeper Phil Mustard had effected a similar dismissal two balls earlier, but that was from a free-hit after Borthwick had overstepped. Lumb bashed the next delivery for six, but missed when aiming another violent swipe seconds later.
4:54pm - Lumb, who now has 80, has batted superbly today, but this is a second stroke of fortune for the left-hander. Another delivery, this time from Breese, is sent into orbit but lands safely.
Glamorgan are easing to victory at Rugby.
4:51pm - The assured Lumb gets lucky when skying one into the off side facing Wood. Scott Borthwick, a fine fielder, appeared to be put off by the sun as he failed to get his hands on the ball.
Lumby must have heard my cheffing skills on the BBQ are on offer tonight, hes in a bit of a hurry!

4:45pm - Chris Woakes bowls Chris Cooke for 19 at Rugby, but it is surely too late as far as the Bears are concerned.
Notts now have James Taylor alongside Lumb and 100 on the board in the 12th over.
4:38pm - The introduction of Gareth Breese yields a Durham wicket as Hales is bowled through the gate for 34, ending the opening stand at 91.
Warwickshire's miserable day continues with Wallace passing 50 in 32 deliveries. Glamorgan require just 29 from eight overs.
4:35pm - Lumb's fifty comes up off 30 balls. Glamorgan skipper Wallace has 41 from 27 and it appears both sides batting second will record comfortable wins this afternoon.
4:29pm - This is getting messy now for the Dynamos. Mark Wood gives up 14 in three balls and England's Twenty20 openers have already put on 71 in seven overs.
Glamorgan need less than five an over, Mark Wallace having followed the lead of opening partner Allenby with a host of fours.

4:26pm - Hales gets in on the act at Durham with successive off-side fours from Ryan Pringle. Notts appear well-placed to extend their 100% record in this year’s Friends Life t20.
4:23pm - Durham need to remove Lumb soon if they wish to retain realistic victory hopes. The left-hander has 39 from 22 balls and is finding the boundary, on either side of the wicket, at will.
Glamorgan end their powerplay in total command on 50 for one.
4:17pm - After surviving a mix-up between the wickets with Alex Hales, Lumb opens his shoulders to clear the midwicket fence off Chris Rushworth. The Outlaws end the fourth over on 35 without loss.
4:13pm - Warwickshire could well end up on the wrong end of a hammering at Rugby. Glamorgan have raced to 33 in four overs, although Allenby has departed for a brisk 24.
A brace of Michael Lumb fours off Ben Stokes give Notts some early momentum.
4:06pm - Smith gets through a quiet over, but the same can't be said of Warwickshire's Rikki Clarke, who concedes three fours to Jim Allenby.
4:01pm - Glamorgan's pursuit of 127 begins. Surely the Welsh side will fancy chasing down such a modest target?
Notts start their innings against the part-time spin of Will Smith.
3:50pm - A 12-ball 20 from Steffan Piolet provides Warwickshire with a much-needed lift. The Bears post 126 for eight, with Hogan striking twice in the final over to complete exceptional figures of 3-11 from four overs.
Gurney’s last set of six goes for 10, which means Durham finish with 154 for four. Breese’s unbeaten 18 spanned just seven balls.
3:45pm - Gareth Bresse struck 29 off 12 deliveries in a losing cause last night and is at it again, racing to 17 from six balls. Durham have 144 as Gurney prepares to bowl the final over.
3:39pm - Hussey does the business again, cleaning up Borthwick, for 44, with another yorker having been hit down the ground for four moments earlier.
3:35pm - Stokes attempts a Jos Buttler-esque ramp off Ball but succeeds only in popping up a simple catch to Taylor at backward point.
At Rugby, Warwickshire finally reach three figures in the 18th over.
3:33pm - Hussey hustles through another quiet over and has excellent figures of 1-14 from three. Durham have not kicked on as they would have liked and will be looking for fireworks in the closing stages of their innings.
3:25pm - David Hussey, bowling from round the wicket, sneaks a full ball through Stoneman's defences. Ben Stokes replaces his skipper, who made 51.
Things continue to look good for Glamorgan, who benefit from a second run-out as Rikki Clarke departs.
3:23pm - Stoneman gets things moving again for the Dynamos with a slog-swept six off Mullaney that brings up a fifty stand with Borthwick. The opener subsequently reaches his own half-century from 40 balls.
Warwickshire are 88 for five in the 16th over at Rugby, with Woakes caught and bowled by Jim Allenby for 25.
3:20pm - A couple of quiet overs stunt Durham's progress, while Warwickshire's run-rate remains below six.
3:15pm - That’s lovely from Stoneman. With fine-leg up, the left-hander gets down on one knee to scoop Steven Mullaney over the infield for four. Durham are 74 for one after 10 overs.
3:10pm - Borthwick has settled in nicely alongside Stoneman, who is once again captaining Durham in the absence of the injured Paul Collingwood.
Warwickshire were just starting to build some momentum, only for Chopra to depart at the hands of Nathan McCullum for 30.
3:05pm - Those early wickets at Rugby have really put pressure on Warwickshire, who reach halfway with just 52 runs to their name.
Durham are one run better off and have only faced seven overs. James Taylor tells Sky Sports commentary team he thinks the Dynamos will be aiming for around 165.
2:58pm - Mustard clears the ropes again, this time a little squarer over cow corner. Jake Ball is the bowler, but the seamer gains swift revenge when Durham’s wicketkeeper chips to mid-on having made 15. Here comes Scott Borthwick.
2:55pm - Chris Woakes is now alongside Varun Chopra and Warwickshire have work to do if they are to avoid a second loss in 24 hours.
Durham end the fourth over on 31 without loss.
It is key for this pair to put some runs on the board with the pitch looking good & @TrentBridge having the likes of Hales, Lumb, Hussey...

2:50pm - Mustard is rarely kept quiet for long. The Colonel clears his front leg and swings Shahzad high over wide long-on for six! Stoneman subsequently claims back-to-back fours, the first with a booming drive through the covers and the second via a fortuitous inside edge.
Warwickshire are in a spot of bother at 29 for three, Nathan McCullum having run out Ateeq Javid.
2:45pm - Michael Hogan strikes a second blow for Glamorgan when trapping Laurie Evans in front for two.
Durham's dangerous opening pair - Mark Stoneman and Phil Mustard - have made a slow start in the face of disciplined bowling from Ajmal Shahzad and Harry Gurney.
2:37pm - The Bears lose their first wicket at the end of the second over with 18 on the board. Darren Maddy is the man to go, caught in the deep off Nick James.
Play is about to commence at the Emirates Durham ICG.
2:34pm - Warwickshire's innings is under way at Rugby and we have confirmation of England's squad for Trent Bridge.

2:20pm - Notts choose to bowl after winning the toss at Durham. The same policy worked well for the North Group leaders in last night's victory over Derbyshire.
2:10pm - Away from the county scene, England name their squad for the first Investec Ashes Test shortly. We will of course have full details on ecb.co.uk.
2:04pm - Warwickshire elect to bat first at Rugby. Their game begins at 2:30pm, with the Durham-Notts game starting 10 minutes later.
2pm - Hello and welcome to ecb.co.uk's latest live blog. After a hectic evening of Friends Life t20 action on Friday, it should be a little easier to keep up with proceedings this afternoon as only two games are taking place.
Warwickshire Bears host Glamorgan at a sold-out Rugby School, while Durham Dynamos and Notts Outlaws will do battle at the Emirates Durham ICG.
