Explanation: Why was Harshal Patel not allowed to continue the final over vs CSK?

Chennai Super Kings batsmen put up an impressive display against Royal Challengers Bangalore at the M Chinnaswamy Stadium. Devon Conway and Shivam Dube led the charge with quick half-centuries for CSK, which resulted in RCB setting a mammoth target of 227 to chase.
RCB bowler Harshal Patel came in to complete the last over of the innings but failed to complete it after two beamers were bowled to Moeen Ali, resulting in his being dropped from the attack as per rules.

What is the no ball rule?

The MCC again amended the Laws of Cricket (41.7) on 1 April 2019, which allows umpires to decide whether the ball is dangerous when the bowler bowls a full toss above waist height. According to current cricket rules, if a bowler bowls two waist-height no-balls or beamers during his bowling quota or spell and the umpire considers it to be dangerous to the batsman, the bowler is dropped from the attack. The amended law gives the standing umpire the right to determine whether a delivery is considered “dangerous”. During the match, the first beamer from Nortje was bowled at 150 kmph and the second one was also bowled at a reasonable pace. As a result, both the umpires decided to bar Nortje from bowling further in the match.

Meanwhile, CSK’s innings got off to a flying start thanks to Conway, who hit two fours in the second over and then three balls later lifted Wayne Parnell over the fine leg fence. However, Ruturaj Gaikwad struggled and was dismissed by Mohammad Siraj in the third over. Conway continued to score at a rapid pace, scooping Vijaykumar Vaishak over the keeper for four and then hitting a precise hook shot to send the ball into the stands as Ajinkya Rahane looked on. The partnership between Rahane and Conway was dangerous, hitting a four or a six in almost every over.

Conway was at his ferocious best, hitting Wanindu Hasaranga de Silva for a massive six in the 10th over before Rahane was dismissed by the spinner. Conway completed his second half-century on the trot with a double in the same over and then smashed Hasaranga for a boundary as CSK reached 97 for two at the halfway stage. Dube joined Conway at the crease and immediately hit Maxwell for a massive six. Conway continued his dominance, hitting Vijaykumar for fours after one and lofting him over the fine leg boundary for another maximum. The partnership between Conway and Dube was finally broken by Kyle Jamieson when he caught Conway in the deep.

CSK ended their innings at 226 for six, with Dubey remaining unbeaten on 52 off just 27 balls. It was a struggle for the RCB bowlers throughout the innings, with the CSK batsmen chasing them from the start. Overall, it was an impressive performance by the Chennai Super Kings, who set RCB a tough target to chase.
