If the Falcons beat Worcestershire Rapids at The 3aaa County Ground this evening, the equation is simple. Derbyshire will qualify for the quarter finals for the first time since 2005.
A win also keeps the Falcons in the hunt for a home quarter final. If two or more teams finish on the same number of points, positions will be decided by net run-rate.
The Falcons will be waiting on other results to confirm their place in the last eight.
Derbyshire will need two out of Birmingham, Leicestershire and Northants to lose, and Lancashire (who play Birmingham) to have an inferior net run-rate to secure qualification.
If there is no result at The 3aaa County Ground tonight, Derbyshire will claim one point and move to 16 points.
This will mean that Leicestershire, Birmingham and Northants will all need to win – and Northants would require to win heavily to help their net run-rate – to stop the Falcons going through.
A point may also be enough to claim a home quarter-final, depending on other results.
NatWest T20 Blast is back, and it’s a massive game at The 3aaa County Ground this evening as the Falcons chase a quarter-final spot. Tickets will be available on the gate.
