I'm happy with that, but I don't think the chase will be easy. This has been a slightly difficult wicket all day, and I suspect 145 would have been match winning. So 131 could be defended. Maybe their long tail (Currie at 7!) prevented them from taking a few more risks in the second half of the innings.
If we're only going to give Topley 10 balls, then our resources would better served by selecting Thompson instead. I'm not saying that Vince was wrong to only give him 10 balls; just that it's a waste to select someone who can't bat or field, if they're only going to bowl 10. (It won't matter for any games which the ECB make Archer available for, because he'll obviously play instead.)
