It's the 20th T20 Finals Day in English cricket. And how much has changed since it all began as the plain, unsponsored Twenty20 Cup back in 2003.

For starters, it is now the all-singing, all-dancing Vitality Blast.

And, of the 18 first-class counties, only seven now go by the same name they started with - two of today's semi-finalists, Lancashire Lightning and Hampshire Hawks, along with Essex Eagles, Kent Spitfires, Leicestershire Foxes, Notts Outlaws and Sussex Sharks, as well as Northants Steelbacks, who technically don't, as they were still giving it the full Northamptonshire.

Also, back in 2003, the T20 was brand, spanking new itself, slightly mistrusted within the game - and not undermined by a jazzy new alternative product being put out there in the marketplace by the same supplier.

But we're all back here at the now undeniable home of Finals Day, Edgbaston, for a 14th time in 20 runnings, in a new high-profile July slot, we have the two oldest and biggest English cricket rivals Lancashire and Yorkshire up against each other at Finals Day for the first time, as well as the more modern-day T20 rivalry of Somerset and Hampshire later, and it looks like bing a glorious summer's day in Birmingham. What's not to like about all that?

The T20 Roses match is always a highlight of the Blast but for the first time the fixture comes to Finals Day.

You have to look no further than the top of the order for Yorkshire's key man with the bat. Adam Lyth is still a wonderful exponent of the art of white-ball batting and is within a stroke of breaking his own Vikings record for runs in a T20 campaign.

He was out first ball in the quarter-final win against Surrey, so the team proved they can do it without him. Don't expect him to fail again.

Harry Brook could play a huge part if Yorkshire are to progress to the final.

His '360' game is both a pleasure to watch and has also so often been a comfort blanket for the White Rose, for his adaptability within the spectrum of 20 overs is such that his way of pacing an innings invariably helps his team secure a firm foothold in a game.

Shadab Khan may not have had a great tournament by his own stellar standards but when he gets it right, he has the potential to take the game away from any team with both bat and ball.

The indicators that that is about to happen have been coming in recent matches and his quickfire 21 off 12 balls and 2-29 in the quarter-final win at The Oval were certainly significant.

Jordan Thompson is another whose series of Blast matches has not been as he would have wanted but he has not earned a reputation as 'the man that makes things happen' for nothing.

Some players simply have the knack of delivering on the big stage and when their team needs it most and Thompson is one of them.

Few Yorkshire supporters will ever forgot his final over in the quarter-final defeat of Surrey and his confidence will be soaring on the back of that, going into Finals Day.

There are times in this season's T20 Blast when some teams had four fielders behind the bowler's arm - essentially, two mid-ons, two mid-offs.

The ability of Tim David’s straight drives was pretty evident for anyone to see who watched Lancashire’s group campaign.

Arguably, he’s saved his best two appearances so far for Lancashire for the Roses matches, especially his 66 at Headingley.

This is Lancashire’s ninth Finals Day, but they are looking for just their second T20 win.

These two Roses rivals lock horns for the first time at Finals Day.

Both sides welcome back some of their England stars - Matt Parkinson and Phil Salt return for Lancashire, while Harry Brook is in the Yorkshire side.

If the two group games are anything to go by where we had a tie and a four-run victory by Lancashire, then we're in for some contest.

Yorkshire have won the toss and elected to bat.
