Shane Warne observed, a tad ruefully, from the TV commentary box that he'd never taken more than 4 wickets in an innings in a Lord's Test. He did give due credit to Shane Watson, nowadays billed as an opening bat who bowls a bit, for (my words) throwing away the script and demolishing the Pakistan middle order with 5/40 from 7.5 overs.
Only some stern resistance from Salman Butt 63/94b (12x4) and a characteristic T20 style 31/15b (4x4, 2x6) from captain Shahid Afridi (playing his first Test for 4 years) took Pakistan to 148 after Australia's last pair had taken the teams total to 253.
105 looked a very good lead in the situation, but the first two days been played in quintessentially English conditions, an irony which some of the players on each side would appreciate. Of course quintessentially English conditions aren't always present even in that country's
Let's hope for a full day's play. If that happens the match could well be decided today.
