I just looked that up. You can mow the pitch, but under umpire supervision. They made a point of saying they took 2mm off the grass. Not sure dry grass grows 2mm overnight?
Without doubt it's moving around more this morning. It might be a morning thing, like in Zim, and they're bowling much better areas this morning.
I know I'm labouring a point here, but that 2mm seems to have made a difference to my eye. These are unbelievably difficult batting conditions. I'm surprised they're not bowling seam from both ends, that's where it's all happening, it's not turning much.
Lights on at 10 in the morning is unusual as well.
