The 28-year-old Babar and Saim Ayub managed to pile up 162 runs for the first wicket in 13.3 overs, with the latter scoring 74 off 34 deliveries.
During his commentary, Doull had criticised Babar for putting his own milestones above his team's. He opined that Babar should have focused on boundaries, instead of 'slowing down the run-rate'.
“Rather than putting the team first...the last little while, that's all that's been happening," he was quoted as saying.
"Rather than looking for boundaries, still, so much firepower to come. Hundreds are brilliant, stats are great, but it has to be team first,” the former cricketer added.
The comment, understandably, didn't go down well with the skipper's fans, some of whom went too far when expressing their anger.

One Instagram user resorted to expletives, and threatened Doull with consequences if he criticised the star batsman again.
The commentator dealt with the situation calmly and wisely, telling the man that his post did not affect him, but the language that he used 'is never OK'.
He posted a screenshot of the post to his Instagram, saying, “So sorry to have upset you Feroz. It’s just an opinion and I get paid for it. It’s ok if you don’t agree but this language is never ok. And my mother has also passed.”
The former Kiwi cricketer received praise for his response from the notables in the sport, including former Pakistan women's cricket team captain Sana Mir and fellow commentator Alex Hartley.
Earlier, he urged Mohammad Rizwan to retire from the game when he noticed him struggling during an inning.
While some took it positively, others resorted to strong reaction over what they thought was an undue criticism aimed at national players.
