Delhi Capitals Player Kagiso was denied a hat-trick because he bowled a wide after taking the first two wickets. Rabada took three wickets off three consecutive legal ball deliveries in SRH’s 19th over In the IPL 2020’s Qualifier 2. As per the rules, to claim a hat-trick, a bowler has to take three wickets off three back to back deliveries (legal or not).
According to the rule book, a bowler gets a hat-trick when he dismisses three batsmen off three consecutive deliveries. Rabada did dismiss Abdul Samad, Rashid Khan and Shreevats Goswami in the third, fourth and fifth ball of his last over respectively. However, one must not forget that he also bowled a wide between Khan and Goswami’s dismissals. Hence, he got three wickets in not three but four balls which is apparently not a hat-trick.
