One of the features of this Ashes series will be the battle between spinner and batters as the rough patches develop rapidly through each Test match. The weather in the UK has been (relatively) dry for months. The pitches are drier than usual for this time of year.
The Australian left arm seamers will help the rough patches to degrade at an accelerated rate outside the right handed batters off stump. This shall bring Moeen Ali and Nathan Lyon into the game earlier as attacking forces. It is likely that the Stokes, Anderson, Broad and Wood will bowl some overs around the wicket at David Warner, if he stays in long enough. This will also add wear and tear to that rough area.
The developing rough isn't just a problem for the batter. It also creates challenges for the keeper and the bowler as well. I know what you're saying; "Test match spinners shouldn't be challenged by the rough? It should be all their dreams come true!"
For bowlers such as Murali or Warne the rough represented opportunity. For most spinners, the developing footholds can represent a threat.
This threat is the pressure of expectation.
