Fitness is important.
A fit easily saves you 10 runs on field which means 10 runs less when chasing.
A fit player can convert 1 run into two runs and if 10 players do that even once in the innings, it means 10 extra runs to defend.
A fit player can convert a half run out chance into out which means opposition player hesitiates to take singles which he would take easily otherwise.
A fit player is confident which gets reflected in batting or bowling eventually besides fielding.
In the past ,the Asian players did not take fitness correctly and thats why lost a ton of games by 10 run or 5 run margins.
Wonder if Akmal brothers know this.
