Why Dinesh Karthik is ideal for India's number 4 slot

Finisher

Karthik has the ability to finish innings

The middle-order requires a batsman who can play both the sheet anchor role as well as the finisher role depending on the match situation. Pandey and Rahane, while they excel in the sheet anchor role, aren't quite comfortable in finishing the innings.

Pandey and Rahane have mainly struggled because of their inability to score quickly during the initial stages of their innings. Karthik, being a middle-order batsman even for his state team, is capable of accelerating at will.

Karthik has played this role throughout his career. In the 2017 IPL, he flourished in the finisher role while he performed exceedingly well as a sheet anchor for his state side throughout the last season.
