Thursday: HANTS v MIDDLESEX, Surrey v ESSEX, KENT v GLOUCS
Friday: ESSEX v KENT, Glamorgan v HANTS, SOMERSET v MIDDLESEX, Sussex v GLOUCS
Obviously us and Essex have the hardest task, because we both need to win three out of three (but if either of us do that, that side will be almost certain of qualifying - especially us with our NRR). But after that, I'd say that Gloucs have the toughest ask. Both games left away from home - and both against current top four sides. Gloucs are very much a home team - take them away from fortress Bristol, and the real ability of their squad becomes a lot clearer. A rain affected win at the Oval is their only away win this season. They couldn't even beat Glamorgan away.
Sussex, Somerset, Kent, Middlesex is my guess for the top four. Not sure which way round to put Somerset and Kent.
