It was a funny banter when one of our member said that South Africa will easily chase the score of 390 runs on the final day, no team will chase a score of 280 runs on the final day in India that easily let alone 390 runs and hence i said i will shave my head if they are able to defeat India . Surviving the final day to draw the match in India is a hard task let alone trying to chase the score.
I did not say easily win the match but rather there is a possibility they can win just like England won the test match with 9 wickets gone and SA already made 400+ runs in the first innings. It's not something impossible as I did not feel 400 runs would be enough but due to Jadeja and Shami, India managed to win by 203 runs. As you said in test matches it's tough to chase down so many runs on the last day, I now can believe that but I'm not still over WC's tragedy and Eng's last wicket win lol.
This is not the end so let's see what will happen in future matches
