Worcestershire Rapids will seal their place in the NatWest T20 Blast quarter-finals if they avoid defeat against Derbyshire Falcons at New Road tomorrow night.
The Rapids could even snatch a home last-eight tie, should Notts Outlaws lose at Yorkshire Vikings and they make up the difference in net run-rate.
New overseas signing Mitchell McClenaghan is set to make his home Twenty20 bow after he was drafted in to replace prolific wicket-taker Saeed Ajmal.
The New Zealand quick has big shoes to fill, although his arrival helped the Rapids arrest a four-game winless run as they beat defending champions Northants Steelbacks by 31 runs on his debut last time out.
Worcestershire director of cricket Steve Rhodes has kept faith with the XI from that game with all-rounder Gareth Andrew and paceman Chris Russell also included in the 13-man squad.
Derbyshire will look to try and end a difficult campaign on a high after managing just a single win from their 13 matches so far to be bottom of the North Group.
