Morning games at Edgbaston start a bit tacky and slow and the ball could grip a bit. Under the lights later the ball can skid on and that's when I always like to bat here.

Nottinghamshire v Worcestershire (1100 BST)
Image source, Rex FeaturesNottinghamshire and Worcestershire were due to meet twice in the North Group, only for their match-up at New Road to be washed out without a ball being bowled.
But it was the Rapids who came out on top at Trent Bridge in July, winning by 28 runs as Moeen Ali took 4-18 to restrict Notts to 133-9 in reply to Worcestershire's 161-6.
Nottinghamshire v Worcestershire (1100 BST)
Worcestershire beat Sussex in last year's final at to win the domestic T20 title for the first time.
And they're back at Edgbaston looking to retain their title after Moeen Ali's stunning century led them to another victory over the Sharks in the quarter-finals.

Nottinghamshire v Worcestershire (1100 BST)
For all their troubles this season in the first-class arena - Nottinghamshire have been relegated from Division One of the County Championship - the Outlaws remain a force in the white-ball game.
And star opener Alex Hales is sure to have a point to prove after losing his England white-ball contract on Friday.

But he was in magnificent form as Notts reached finals day with a 10-wicket quarter-final win over Middlesex, hitting seven sixes in an unbeaten 83 off 47 balls.
