It can turn (pardon the pun mate!) so quickly on those wickets, that it wouldn't surprise me if India were bowled out for under 200 again. Lyon looks threatening again, although he will need help from someone to a. keep the pressure on and b. chip in with regular wickets.
It has been a wonderful Test match so far, hasn't it? I wonder what India will feel comfortable with...maybe a lead of 150?
I can't help but think that the lapses from Renshaw, Handscomb and Shaun Marsh might end up proving costly, as harsh as that may seem.
