I don't see any particular reason to be concerned about Wood, beyond the fact it's Mark Wood and he's prone to something snapping at any moment. You'd expect him to be used in short bursts and 11 overs out of 75 isn't too far off his share. We bowled them out cheaply in the first innings, his spell in the second was expensive and the game had basically gone by the point he might have come back on.
The problem today was clearly the batting. Dreadful stuff from Pope, Root and Brook. We just needed to sit in for a while, wait for the ball to soften a little and the pitch to flatten and bat them out of the game.
The question now is whether this match is more Lord's 2005 (where we lost but rattled the Aussies first time around in a signs of things to come) or Brisbane 2013 (where we had a good first day only for the wheel to come off the whole tour in spectacular style). I fear it's closer to the latter.
