Always good to see forgotten players like Imam-ul-Haq among the runs again. He is just 30 years old, but his career is all but over. The last time he played in PSL was in 2020, and the last time he represented Pakistan in T20I format was long back, in 2019. He has been branded as a test player not suitable for limited overs cricket, and has been excluded from this format for quite some time. During the match against Karachi Region Blues, he scored 71 from 40 balls. One single innings may not make it possible for him to get into the PSL, but repeated performances can get attention from important people.
It is sad that Imam-ul-Haq is being ignored yet he is still in his best years but his latest play of 71 runs off 40 balls shows that he could fit into busy modern T20 cricket. His missing in major leagues since 2020 could maybe be blamed on opinion of people about his style and not lack of skill to play since his high average in other styles shows he is very steady player.
And you are right Imam can save his career just like other top level batters who had managed to change their game in the same way. Single good game is very good start, yet he must do such shows of high scoring couple of times more.
