Warner doesnt have too much between the ears, but being the way he is, i'd say he is happy to cop as much as he serves out and De Kock must have said something to set him off like that. Not any good pretending any of us know what has gone on, so best put your pitchforks and torches away for now.
As for embarrassment to the sport, well It's not like the he is on cctv footage beating someone senseless in public..not that a professional athlete would ever do that in this day and age..
As for the cricket, some great fight from the saffas in their second innings, but this Australian line up looks to be a bit beyond them, genuine concerns for them when a few of the underperforming big boys of that side decide to call ot a day, which on current form seems sooner rather than later.
