As mentioned before I have nothing against the guy but I have to see a glimpse of something to be convinced he's ready for this WC - or at least accomplish himself as one of the two best openers for the side!
I'm not sold on Imam as of yet because firstly, he lacks shots in armour and as a result it comes to no surprise that his strike rate is suffering. Against the top 5 sides (SENAI), he's only scored well against South Africa but even then that came at a SR of just 81. These runs do not enhance the team's fortunes. I just think at this stage of his career he isn't ready and shouldn't be opening until the WC is over.
There are 2 alternative strategies:
1. I know Abid has only played 2 x ODIs but from what I've seen of him he has the gift of timing, so he deserves chances in this series, unfortunately Inzi will use his influence and interfere with his selection because that's just inevitable.
2. Open with the T20I opening combo: Fakhar and Babar, with Haris at 3 (in his preferred spot).
After the WC I'd take out Haris Sohail because he's already 30 and is simply injury prone, so I don't think he'll make the next tournament in 2023. I would also do the same for Abid Ali if he ends up starting in the WC. I'd bring Babar back to 3 and invest in Imam - give him 18-24 months.
Babar had a lower SR in SA, and again, SA is SA, you cannot take it away from him.
I don't think there is a world of difference in the 84 SR of Babar and 80 of Imam, and then his SR from year one was 76, year two was 83.
He has had a bit of a spurt in 2019, which again, can happen to young players.
He plays on leg and offside, and I agree, needs to work on that next gear.
Babar getting this kind of protection and Imam not is clearly bias.
They both deserve to be on the team, and yes, I agree that ton by Abid was excellent, but to play with a player who has one international match in the WC is stupid planning. Had he played, I would agree with you, but our management dropped the ball there. Imam will be the long term investment and it will come with bumps and bruises.
As I said, his showing in SA was very impressive, and gives me hope for his future.
Today is not a good showing, and I myself agree that he needs to rotate better and pick apart the bad balls more often, however this is a similar issue that Babar has faced as well, as he tends to start well, and then slows down as the innings progresses. An 81.6 SR, is not too far off from Babar himself, who in the series had a lower SR.
Imam should be the guy, and deserves to be the guy barring Abid, which PCB dropped the ball on, and for the WC it is likely too late to implement in the lineup.
