Azharullah, Buck, Cobb, Gleeson, Holden, Hughes, Keogh, Kleinveldt, Rossington+, Newton, Sanderson, Wakely.
No Duckett or Levi of course; Crook presumably left out on form and White because the pitch is likely to be seamer friendly. Even so one of Sanderson or Gleeson would seem most likely to be left out leaving Keogh and Cobb (or even Hughes) to try and produce a bit of spin
I had hoped to see some comment about the inclusion of Hughes but as usual there is nothing on the Northants website. I assume he is playing on a game by game basis but he would be a decent acquisition, particularly for the T20s.
