Their game to lose now I think, 170 lead and the best part of 200 overs to go means they can tick over for the morning and then have a slog later in the day to put 300ish as a target leaving us needing to bat out on a day 5 pitch. That said the pitch has been lifeless today and played more like a day 2 pitch so maybe conditions won't be too tough for us. Either way we'll need to bat well.
That is all, of course, based on us not seeing a spectacular collapse that sees us chasing 200ish with 4-5 sessions to do it.
