Rangana Herath's magic hands has taken six wickets which folded the Aussie batting line up pretty soon.by the close of play on the third day, it was impossible to say which team had the upper hand. if Srilanka could put a target of just over 250 runs on the board,i am sure the spinners will give the Aussie a very hard time in the fourth innings,the fate of the match all depends upon how Srilanka is going to bat today 
Australia would be wondering how that turnaround happened. When that second wicket partnership was going strong, they would have thought that there was no way that Sri Lanka would gain the upper hand.
This match is going in the way of a first test match. Becuase in first test match also Australia was in good position in the first day and later on slowly SL take the control of a match. This match also may end in the same way if Australia doesn't control SL batsman in the second innings. SL has to put up at least 250 runs to defend the score. Hopefully, SL will bat well in this second innings.
