Yeah in some circles cricket still has this anachronistic reverence for averages, not outs, etc.Pakistan not even trying to come back for 2 off the last ball of their regular innings when the ball went to long on was certainly something. Not like they could have used an extra run or anything.
I theory, you should always go for that extra suicide run from the last ball in the first innings. You cop the run out, just like the Aussies did against Oman.
In the old days where wickets lost could be a tie breaker, I understand it. But not now.
