Three runs from the first two overs for Somerset openers George Thomas and Andy Umeed after Leicestershire elected to have a bowl.

Goldsworthy, Rew, Dickson, Vaughan, Green, Aldridge, Leach, Davey and Meredith to come for Somerset

Bears captain Ed Barnard, who took the decision to bowl first, takes responsibility for sending down the first over as well.

Will Smale gets bat on ball a few times and opens the scoring with the final delivery of the over, clipping Barnard off his pads for four to long leg.

Leicestershire win toss and we are underway at Taunton.

Warwickshire, who have won the toss and put their hosts in, make two changes from the side that triumphed in Friday’s quarter-final against Worcestershire.

Opener Rob Yates returns, with 18-year-old Hamza Shaikh also back in the Bears’ line-up as Zen Malik and Theo Wylie make way.

Glamorgan are unchanged from the team that defeated Yorkshire in their final group match earlier in the week, here at Sophia Gardens.

In terms of points, Glamorgan have been the outstanding team of this year’s tournament so far, having topped Group B with six wins and just a single defeat.

Their eighth group fixture – against today’s opponents Warwickshire – ended in no result due to the weather, but hopes are high that the Welsh county can repeat their triumph of three years ago, when they defeated Durham to lift the trophy at Trent Bridge.

Kiran Carlson and Billy Root are the only survivors of that 2021 vintage, while the Bears – whose sole success in this competition came in 2016 – are skippered by a player who has also been around for a while.

All-rounder Ed Barnard, who won the T20 Blast with Worcestershire in 2018, has led from the front, topping Warwickshire’s run-scoring charts by some way with 419 to date as well as collecting more wickets (15) than any of his team-mates.

However, Barnard was upstaged in Friday’s quarter-final by teenager Kai Smith, who smashed an unbeaten 130 from 104 balls to haul the Bears out of trouble and steer them to victory against Midlands rivals Worcestershire.

The two teams lining up here have a fine tradition in the one day arena with both having laid hands on this trophy in the last five years, Leicestershire last year and Somerset in the last one at Lord's in 2019.

Historically Somerset have a fine tradition in limited-overs cricket. Between 1979-83 they lifted five pieces of limited-overs silverware in five years and interim coach Paul Tweddle asked his team to try and reconnect with that rich history this week.

Leicestershire have to dig deeper for their own history in this, or its equivalent wins in 1974 and 1977, but, perhaps more importantly, they have recent muscle memory of lifting this cup after beating Hampshire at Trent Bridge last September.

The Foxes worked their way to Taunton today beating Hampshire in the quarter final by three wickets with a ball to spare while Somerset had their collective feet up after topping Group A with six wins from eight to earn home advantage.

In addition to ball-by-ball coverage here on BBC Sport, via most smart speakers there’s now a new way you can enjoy ALL our cricket coverage.

For most smart-speaker devices, all you need to do is ask BBC Sounds to play the full title of the event you want.

So, for example, just say "ask BBC Sounds to play Somerset v Leicestershire".

The BBC Weather forecast for Taunton today is "Sunny intervals and a gentle breeze" with highs expected of 21 degrees centigrade

Not surprisingly, given how comparatively close they are geographically, with only pretty much the Bristol Channel in between, it is almost exactly the same outlook for Cardiff, where the breezes are expected to be "moderate" rather than "gentle". You'd think it might be the other way round, given that Dylan Thomas was a Welshman!

Good morning and welcome to the hundred . . . No, not that one!

This is not the hundred balls per innings version.

This is its big elder brother . . . hundred overs per match.

Still loved by many. And, if you understand what we mean by the term 'overs', this is definitely the place for you for the next seven hours or so.

One-Day Cup semi-finals day . . . Glamorgan v Warwickshire in Cardiff. And, on the other side of the Severn Bridge, Somerset v Leicestershire at Taunton.

The prize is an appearance on 22 September in the final at Trent Bridge, Nottingham, where two of today's four semi-finalists have lifted the trophy before - Glammy in 2021, the first year the final got moved from Lord's, and the Foxes a year ago.
