Timothy and James replace Richard and Christopher

Worcestershire won the toss and will bat.

Warwickshire make two changes. Ambrose and Anyon come in for Johnson and Woakes.

Anyon comes in with a chequered record in T20. He is the only Bears bowler to have taken a hat-trick in the competition but also holds the record for the most expensive analysis by a Warwickshire player: 4-0-60-1 against Gloucestershire at Edgbaston in 2006.
