The selection is pretty much as expected, with marquee overseas signing Mohammad Nabi unavailable as he undergoes his Covid quarantine following his arrival in the UK last weekend.
The Steelbacks other overseas star, South African Wayne Parnell, is in the squad and is set to make his T20 debut for the club, having already enjoyed a solid season in the LV= Insurance County Championship.
He will be facing his former team-mates as he left Worcestershire at the end of the 2019 season, having helped the club to the T20 Blast Final for two years in a row.

The other County players set to play their first matches of the summer are skipper Josh Cobb, batsman Richard Levi and spinning all-rounder Graeme White.
Red ball skipper Adam Rossington will keep wicket.
