Anchor in white ball is not a scam. Maybe in T20 cricket. Not the case in ODI cricket .

Klaasen is the only real outlier who scores big and ridiculously fast in the middle order over a significant sample size.

@Mamoon as it may be valuable education for both.
The word "anchor" refers to a heavy object used to keep a ship stationary, which makes it a terrible analogy for batting in cricket, where the goal is to keep the ship moving. A better term would be "carry," as it reflects a player’s ability to lead the team forward.
Batters in ODIs need to block, milk, and hit out to maintain momentum. In the past, Inzi or Yousuf for example had all those gears for their eras. Babar Azam does this relatively well, but the only player who truly fits the "anchor" description is Fakhar Zaman, given his consistency and a strike rate of 93.
The issue with Imam-ul-Haq is that his second 50 runs often mirror his first 50, showing a lack of gears to accelerate and truly "carry" the team. In the list you shared, batters have strike rates ranging from 80 to 110, meaning "anchoring" is being done at different paces. The ones scoring at 90+ are valuable in modern ODIs, and those approaching 100 are world class.
This discussion is about openers not 3, 4 and 5 though. The openers from the teams like India and Australia maintain much higher strike rates in the Powerplay. Aggressive starts are a hallmark of successful ODI teams, capitalizing on fielding restrictions to build momentum. Can you name a current opener from India or Australia who plays at a strike rate as low as 83 in the Powerplay?
Imam can become a good opener but should be forced to develop his game. Pakistan should look at other options.
