Surrey, who claimed the biggest points haul in the group stages, must get past Sussex and Ladbrokes make them 8/11 to do so. They should progress at The Oval and Chris Nash, the highest runs scorer in the competition, is a must for top scorer at 9/2 with Ladbrokes.
Durham head to Taunton for the other semi final to take on Somerset and as 6/5 outsiders (Skybet), Durham can be considered a value bet. With identical league records, these two teams will be very closely matched and perhaps Phil Mustard (7/2 with to top score for Durham) can be the difference. Durham are 7/2 with Paddy Power to win outright.
Doubling up Durham with Surrey to both win is 8/3 with Skybet.
