Craig Miles comes in for the second over.

Top edged four over keeper Alex Davies's head for Ben McDermott, followed by a straight drive for a second boundary.

10 off the over. 11 for McDermott. Jasmes Vince yet to face.

Olly Stone balls the first ball . . . and we're off.

Five dot balls in the over. Good start.

As well as this text commentary, there is ball-by-ball radio coverage available for you this evening.

It will go out on all frequencies for both stations - and online coverage will therefore be on the BBC Sounds app.

The Hampshire commentary will come from Kevan James and Stanley Marisa on BBC Radio Solent.

Hampshire Hawks have won the toss and skipper James Vince has opted to bat.

They make one change, with Nathan Ellis coming in for Toby Albert.

This is Hampshire's first visit to Edgbaston since they beat Warwickshire last September in the County Championship to raise hopes of a first red-ball title in 48 years, only for Vince's men to then lose their last game to Lancashire - and hand the Bears the title.

Birmingham Bears make one change from their final group defeat by Lancashire on Sunday as Craig Miles returns for fellow paceman Henry Brookes.

Adam Hose, Sam Hain (to mirror his red ball form) and Chris Benjamin have all been in the runs, but Dan Mousley is really the man in form, having slapped 157 in three innings in the space of nine days.

Birmingham Bears: Brathwaite (capt), Stirling, Davies (wk), Hain, Hose, Benjamin, Mousley, Lintott, Briggs, Stone, Miles.

Hampshire: Vince (capt), McDermott (wk), Prest, Weatherley, Whiteley, Fuller, Dawson, Ellis, Wood, Wheal, Crane.

Officials: Tom Lungley, Graham Lloyd, Dean Cosker.

Yorkshire have already somehow disposed of Surrey, and tonight it's the Bears up against Hampshire, a switch from its place on Friday in the original schedule.

Edgbaston had already been pre-booked for Saturday's second England-India T20 international - and the first priority was preparing for that. So this second semi was brought forward 24 hours.

Clearly someone on high needs a little help looking at the fixture list next season to avoid another such kerfuffle.

The other two quarter-finals are on Friday (Lancashire v Essex) and Saturday (Somerset-Derbyshire). And it remains to be seen how many players from England's T20 squad might be allowed to turn out for their county teams.

Lancs have five in the squad. Essex have none.

One of that T20 squad, David Willey, was allowed to play for Yorkshire last night against Surrey - and Lancs wicktkeeper Phil Salt hasn’t ruled out his chances either.

"There is a possibility," he said. "But that decision’s going to be up to the medical team. If that window does open up, and there is a chance then I’d definitely love to go back and play in a home quarter for Lancs.”

Edgbaston is generally considered the home of the T20 Blast.

Of the 19 previous Finals Days, the 24,000-capacity still-developing Birmingham stadium has staged 13 of them - including the last nine. This year's, on Saturday week (16 July) will be the 10th in a row.

Yet the Bears themselves have only made it to Finals Day four times.

As Warwickshire, they appeared in the very first final, beaten by Surrey at Trent Bridge in 2003. But they did not make it back again for another decade until they revinvented their T20 brand as the Birmingham Bears in 2014.

They won it as Birmingham at the first attempt in 2014, returned to Finals Day a year later to be beaten in the semis, then made Finals Day for a third time in four years when they lost in the final to Notts in 2017.

But it has been fallow times again since. Last year's quarter-final defeat at Canterbury by ultimate winners Kent was the first time in four years the Bears had made it out of the group.

What a transformation this year though. The Bears batters have simply gone out and smashed it.

In seven of their 14 group games, they have totalled 200-plus scores to help them top the group. All capped by their English county record 261-2 against Notts at Trent Bridge - and the 228-8 v Worcestershire at Edgbaston, to win by 144 runs, also an English record.

One of the joys of Twenty20 cricket in England over the past 20 seasons is the way success in this competition has been so spread about.

Of the 18 first-class counties, in 19 stagings of the T20, 13 have lifted the trophy.

Four, including Hampshire, have won it twice (although not at Edgbaston. Their two triumphs were on home soil in Southampton in 2010 and at Sophia Gardens, Cardiff in 2012). And only Leicestershire, winners in 2004, 2006 and 2011, have done it three times.

Hampshire do, with Lancashire, share the record of most appearances at Finals Day, however, having made it to the last four on eight separate occasions, most recently when they lost off the last ball to Somerset just a year ago.

But to get to Edgbaston again, and give themselves the chance of matching Leicestershire's hat-trick of triumphs, they will have to repeat the result from when they first met the Bears in this compettiion, on this same ground at the same quarter-final stage in July 2010.

Skipper James Vince is the only survivor from that night when, as a 19-year-old in his first season, he saw his side home with an unbeaten 66 from 52 deliveries, to win by five wickets with just one ball to spare.

Welcome back for the second chapter of the story of this year's T20 Blast quarter-finals.

Thanks for rejoining us in this parellel universe away from the world of politics, Love Island and Bazball.

After last night's eyeball-popping last-over drama at The Oval, we have headed north up the HS2 trail to Birmingham, where the Bears host Hampshire Hawks.

Brendon 'Baz' McCullum once biffed 158 not out off 64 balls on this ground when he was a Birmingham Bears player, still the club's record T20 score, seven years ago almost to the night.

And it was here only on Tuesday when England finished off India in the Test match and the Bazball phenomenon currently sweeping the nation reached its peak. But there will hopefully be no need for any more Bazball or Nighthawk talk this evening.

Tonght is not about Nighthawks but the Hampshire Hawks - and not about Bazball, but the Birmingham Bears. And the chance for one of them to become the second side to book their place alongside Yorkshire back here at Edgbaston on Finals Day - on Saturday week.
