If I tell you the fastest ever recorded speed of a ball in the history of IPL is 173.9 Kph, it raises your eyebrows and you will be wondering how this delivery couldn’t make a world record. The ball which was recorded by the speed tracker bowled by Morne Morkel and Chris Gayle was at the batting end during the IPL league in 2013.
When the screen pops up the speed of ball, Chris Gayle was flabbergasted, because the speed tracker was showing the whopping speed 173.9 Kph, which is around 12.6 kilometer quicker than Shoaib Akhtar’s international record. But this is all happened due to technical error in the Hawk-eye system.
Coming back to your question, the fastest legal delivery in the history of IPL is bowled by Dale Steyn, he bowled a delivery that did clock the speed of 154.40 kph and it is the fastest delivery that is ever bowled by a bowler in the IPL.
