Leading the charge was former Indian cricketer Sanjay Manjrekar, who was watching Harmanpreet's heroics from close range, being part of ICC's commentary panel for the tournament.
Even Sachin Tendulkar could not keep himself from lauding the 28-year-old hard-hitter. When the 'God' himself brands your knock as incredible, you know you have done something out of this world.
Former India opener and another cricket pundit Aakash Chopra went even further as he showered praise on the middle-order batsman, calling her knock the best by an Indian in a World Cup knock out game, including men's cricket.
Best innings by an Indian in a World Cup knockout game...yes, I'm including men's cricket too. Harmanpreet Kaur...is writing history. #WWC17— Aakash Chopra (@cricketaakash) July 20, 2017
Indian men's team's head coach Ravi Shastri was also quick to take to twitter and congratulate the Punjab girl for her power-packed show.
Skipper Virat Kohli too joined the bandwagon and lauded Harmanpreet for her record-breaking knock.
Virender Sehwag brought in his trademark style into congratulating Harmanpreet for her colossal effort, and declared himself to be a fan of the batsman.

The International Cricket Council and Cricket Australia also joined in to congratulate the Indian on her great feat.
