Rehan Ahmed hits a four off Brett Hutton but he manages once again to put the brakes on with just two singles from the final five.

Rehan drops the ball into the leg side and takes a quick single to brother Farhan. Stephen Eskinazi has to get a right wriggle on late as Farhan Ahmed takes a shy at the strikers' end.

The hands on heads from the Notts fielders suggest that was close but the replays suggest the Leics opener was probably home.

Promising signs for Naavya Sharma, who gets Alex Lees fishing and missing outside off stump in a tidy over.

Just three conceded by Sharma, but Middlesex will be keen to try and separate this opening pair during the powerplay overs - of which four remain.

Rehan Ahmed, returning here after completing his Hundred commitments with Birmingham Phoenix, hits his first ball from Brett Hutton for four.

A momentary scare for Ben McKinney as he drives uppishly at a wide one from Toby Roland-Jones, but the ball's out of reach of Middlesex skipper Ben Geddes at mid-off and races to the rope.

McKinney's begun well here, with 15 of the visitors' 23 runs so far to his name and a more sedate seven for Alex Lees.

With that said, Lees has centuries to his name in both Durham's last two 50-over meetings with Middlesex - so definitely not a batter the home side will want to let settle.

A first boundary as Rishi Patel lifts Dillon Pennington elegantly over square leg for four and then follows it with a maximum over long leg.

That was a well timed hit.

Patel is a dangerous batsman when he gets his eye in and it looks like he has. That is 14 from his 12 balls.

Stephen Eskinazi is tucked up by Brett Hutton who is rapped on the pad with the fifth ball of another tight over from Notts.

The former Middlesex man scrambles a single off his legs to deny the maiden.

Plenty of cloud above the rain-starved Radlett surface, but so far that isn't offering any assistance to the Middlesex seamers.

Ben McKinney has his second boundary of the morning now, punching Toby Roland-Jones through the covers. A solid start from the Durham openers.

A tidy over from Dillon Pennington sees the Foxes take three singles and the Notts bowler respond with three dots.

The outfield is a very pale brown and the wicket a very pale yellow. No wonder both have opted for extra spin options.

Ben McKinney gets the Durham innings up and running, clipping Toby Roland-Jones to the square leg fence, but it's otherwise five dot balls from the experienced paceman.

Alex Lees will face his first delivery of the semi-final from Naavya Sharma.

We have lift off in front of a decent-looking crowd.

Stephen Eskinazi takes the first single off the second delivery from Brett Hutton, who is steaming in from the Pavilion End.

Rishi Patel dabs a scruffy looking shot for two off the final ball.

Middlesex have made four changes to the side that beat Sussex in their final group fixture here on Tuesday.

Seam trio Toby Roland-Jones, Naavya Sharma and Tom Helm all return while young batter Caleb Falconer, who has been on duty in The Hundred up to now, replaces Aaryan Sawant.

Durham, who are unchanged from the side that thrashed Lancashire in Friday's eliminator, have won the toss and bat first.

Notts have won the toss with Haseeb Hameed electing to bowl.

Just one change from the side who beat Yorkshire on Friday with Liam Patterson-White adding a spin option (and a bit of lower order hitting) at the expense of the injured Lyndon James.

For Leicestershire, there is just the one change from the side who lost to Kent on their last outing in this competition with Rehan Ahmed adding heft and spin also, the England man coming in for Mohammed Rizvi.

Leics: Eskinazi, Rishi Patel, Rehan Ahmed, Shaikh, Kelly, Cox, Holland, B Green, A Patel, Scriven, A Green.

Notts: Martindale, McCann, Munsey, Hameed, Verreynne, Haynes, Patterson-White, Ahmed, Stone, Pennington, Hutton.

Middlesex’s group record was the best of any side in the tournament – winning seven of their eight games to finish with 28 points.

At home, they overcame Essex, Glamorgan, Yorkshire and Sussex while their victims on the road were Hampshire, Derbyshire – and today’s opponents Durham, who they defeated by three wickets in a thriller at Chester-le-Street.

Durham’s group record was a little more mixed – after winning their first three games they ended up with five victories and three defeats, the latter against Yorkshire, Middlesex and Worcestershire.

But their superior run-rate was enough to secure third place and an eliminator at Old Trafford on Friday – where they thrashed Lancashire by 162 runs to seal their semi-final spot.

Only net run rate separated these two sides in the Group stage when both the the Foxes and Outlaws finished locked on 20 points with five wins with Leicestershire edging it by 0.34.

In layman’s terms that was probably nothing more than a dropped catch here or there during the eight matches but it was enough to give the Foxes home advantage and safe passage to today’s semi while Notts had to battle past Yorkshire on Friday.

Who benefits from that is anybody’s guess but Notts can at least carry momentum into this while Leicestershire’s last game in this format being a six wicket loss to Kent on 9 August.

When they met back at the end of July it was Notts who bossed it too skittling the Foxes for 199 and chasing it down with 45 balls remaining for an emphatic five wicket win.

Middlesex will be hoping their perfect record at Radlett in this year’s One-Day Cup helps to propel them to a first List A final since 1990.

Ben Geddes’ side topped Group B with seven wins from eight games – including all three of their fixtures at the picturesque Cobden Hill ground that provides variable bounce, but also potential for fast scoring.

However, Middlesex’s success in the tournament so far has arguably been based around their strong seam attack – young pacemen Naavya Sharma and Noah Cornwell, bowling in tandem with the experienced Toby Roland-Jones, have both taken 15 wickets apiece.

The trio combined to flatten Glamorgan for just 66 on this ground earlier in the competition and should again spearhead the Seaxes’ bid to secure a place at Trent Bridge next month.

Durham, though, are yet to taste defeat at Radlett in this competition – they edged home by two runs in a rain-affected contest back in 2021 while their second visit, three years later, was washed out entirely.

Outlaws batter Jack Haynes admitted he wondered whether he had “forgotten how to bat” after returning from a quad injury that had kept him on the sidelines since July 18.

The answer was an emphatic no after the stylish Haynes helped Notts recover from 1-3 on his way to an unbeaten 116 (in 99 balls) alongside Kyle Verreynne who made 105 as Notts eventually eased past Yorkshire at York on Friday.

“No matter how long it's been, you always think, ‘Have I forgotten how to bat or not?’ So, it was nice to hit a couple out of the middle. Kyle out there with his class made it a lot easier for me.”

If Notts can get past the Foxes today they will have a home final with the last match of the Metro Bank One Day Cup on 20 September at Trent Bridge.

“It would obviously be nice to have a carrot of a home final, but we’ve got a big game ahead of us (first).”

Hands up – who is the only member of Durham’s victorious One-Day Cup side from 2014 still in with a chance of repeating that success 12 years on?

Easy, of course. It’s none other than recent England Test captain Ben Stokes, whose unbeaten 38 nudged Durham over the line in a low-scoring Lord’s showpiece against Warwickshire that day – and will now look to play a key role in taking his county back to another final.

Stokes is just one of several experienced faces in the Durham line-up, along with Alex Lees, David Bedingham and two other former winners of the tournament – Ollie Robinson, who triumphed as a Kent player in 2022 and Colin Ackermann, part of the Leicestershire side that claimed the trophy a year later.

Durham only just squeezed into the knockout stage this time, losing two of their final three Group B games – including a three-wicket loss to Middlesex at Chester-le-Street.

But the men from the north-east then underlined their credentials in Friday’s play-off at Old Trafford, thrashing Lancashire by 167 runs with almost 14 overs to spare.
