And it would seem that DRS has blown the whole thing up. Again. Stuck in the office so haven't seen it, but everyone seems to be saying it was a ridiculous decision.
Nonetheless the issues here are more subtle than many in the media (and indeed the teams) seem able to understand or prepared to acknowledge. Given the impossibility of proving a negative, I was convinced before (and am now even more so) that it's a complete waste of time for a batsman to call for a review when given out on the field and the point of dispute being whether he actually hit it or not.
And whilst the third umpire will no doubt be on the receiving end of plenty of stick, whisper it quietly but he might just have made the correct decision under the terms of reference of DRS. Just about everyone thinks (or says so) that the third umpire is there to decide if the batsman's out or not. The third umpire is actually there to decide if the on-field decision should be upheld or overturned. As we've seen in this series several times already, the two are by no means the same. The Australian team and most of the media seem stubbornly unable to understand this. Actually, I have sympathy for the players, asked to make decisions on using reviews in the heat of the moment. It takes a cooler head than is almost possible to leave the crease when you know you haven't hit it.
Maybe the third umpire SHOULD be there for deciding if the batsman's out, but he isn't. Quite probably he would have made a different decision (in Khwaja's case, and others previously in the series) if he WAS there to decide that. But one should be careful for what one wishes in all this. Changing the terms of reference of DRS to improve decision-making in this way could, in my view, make a bad situation worse. Do we really want the game umpired from the stands?
Umpires are clearly regarding DRS as something of a crutch (they too, perhaps, forget the subtleties in the definition of the third umpire's role). I very much doubt that the intrinsic quality of umpires has diminished. I am coming to the view that India may have it right. Scrapping DRS or at least (re-)limiting its use may well have the effect of improving on-field umpiring again. This may be the best way forward.
