Without taking away the credit from Sri Lankan batsmen who batted superbly, I do agree that scoring 154 in 21 overs is easier than scoring 196 of 29. When SL batted, it was virually a 20-20 match and scoring 154 in a 20-20 match is not such a great total. Sustaining a scoring rate of 7 for 21 overs is easier than doing so for 29 overs.
