Bit harsh on Vihari, he's only been in the UK a few days and first net was yesterday. As others have posted the consistent failure to knock over the lower half of the order was the problem here. It would have been easier for Vihari to bat from number five at a different part of the day as opposed to first drop at around 1845 with Broad steaming in.
I didn't watch any of yesterday, but how did the bowling fall away? Did Notts just bat well? Did we run out of steam? Or were they just following bad plans? I can remember England having g the same problem.
