In high-octane T20 cricket, where boundaries often dictate the momentum of a match, a select group of bowlers have mastered the art of restraint, denying their opponents any scoring opportunities.
In the Indian Premier League (IPL), where explosive batting reigns supreme, these bowlers have achieved a remarkable feat by not conceding a single boundary (4 or 6) in an innings while bowling all four overs.

In the IPL 2024 match number 28 between Kolkata Knight Riders and Lucknow Super Giants at iconic Eden Gardens in Kolkata on Sunday (April 14), KKR mystery spinner Sunil Narine showcased his miserly bowling skills.
The right-arm spinner finished with figures of 1/17 from his full quota of four overs and did not leak a single boundary in his effort. The Caribbean star all-rounder didn't even concede a double in his spell.
Let's take a look at the elite list of bowlers who have achieved this remarkable milestone the most times:
