Captain Mahendra Singh Dhoni (@msdhoni) and Ajinkya Rahane (@ajinkyarahane88) were the second and third most mentioned Indian cricketers.
Dhawan smashed 137 to lay the foundation for India's huge victory in Melbourne yesterday.
While Dhoni's aggressive captaincy and field placements drew praise from cricket aficionados, fans were also impressed with Rahane's 79 off just 60 balls in the outing against the Proteas, which India won by 130 runs.
The moment Dhawan - later adjudged Man of the Match - reached his century, Twitter went abuzz with posts congratulating the left-handed batsman.
A total of around 770,000 tweets were posted related to the match.
