Make another 300 then put them in again and over by stumps on 4th day for more party time, would be the script
Bailey last chance to actually play a proper Test innings.
He probably needs a century or an innings of some substance to make the trip to South Africa for our next Test series.
If Warner and top order play too well he will not get a chance.
In any case, if this is the only Test series he plays, he will treasure this experience for life.
28 off a Test over will still be a personal fun thing to know you did even though he'll know his Test series as a bat has been not what you really want.
