India opener Rohit Sharma revealed the reason for his quiet celebration despite having slammed a century in the fifth ODI against South Africa on Tuesday. Rohit, who was involved in two run outs, that of skipper Virat Kohli and middle-order batsman Ajinkya Rahane, said two batsmen before him were run out so the pressure had mounted on him to deliver and he just wanted to focus on how to carry the same momentum till the end.
