The Indian Premier League (IPL) has witnessed some stunning performances in the past, ranging from nail-biting run-chases to match-winning spells. Batters have their say on most of the occasions but there are few instances where they bowlers prove the mettle. One game during the 2019 season was different-not for a last-ball victory or a batting masterclass, but for a record-shattering bowling debut that left fans stunned. The stage was set for a classic T20 game on April 6, 2019, when the Mumbai Indians played the Sunrisers Hyderabad in a high-voltage encounter. MI posted a below par total of 136 at the loss of seven wickets in their allotted 20 overs. With the likes of Rohit Sharma, Quinton de Kock, and Kieron Pollard in the team, it wasn't their batting that was the show-stealer. Rather, the magic was created with the ball. A Debut to Remember Mumbai Indians' innings had its ups and downs. While Kieron Pollard played a blistering knock of 46 runs off 26 balls, the rest of the batting lineup struggled to score runs against the SRH bowlers. Bowlers like Mohammad Nabi and Rashid Khan kept it tight for Sunrisers with their spin, and chasing 137 didn’t seem like an impossible task for a lineup that had David Warner, Jonny Bairstow, Manish Pandey, Deepak Hooda and Yusuf Pathan. However, what followed was an absolute cricketing drama. Chasing 137, Sunrisers Hyderabad lost Jonny Bairstow as their first wicket. And then happened a moment that will be remembered in IPL history. A new-ball fast bowler, making his debut, came charging in with raw pace and good bounce. His hot-blooded spell tore through the Sunrisers' top and middle order. In just 3.4 overs, the game had swung totally in favor of Mumbai. Image Source: X/Twitter He bowled aggressively, aimed at the stumps, and bowled or caught batters with smart variations. His victims were David Warner, Deepak Hooda, Vijay Shankar, Rashid Khan, Bhuvneshwar Kumar and Sid Kaul. With a spell that lasted less than four overs, he not only rattled SRH's batting but also scripted his name into the record books. The Record-Breaking Spell By the time the innings ended, SRH were bundled out for a mere 96 runs in 17.4 overs, giving the visitors an easy 40-run victory. But more than the victory, it was the bowling figures of the debutant that stole everyone's attention. This new pacer ended with the figures of 6 wickets for only 12 runs, the best bowling figures in IPL history, which still maintains to date. He was rightly adjudged Player of the Match and also headed the MVP table for his game-changing effort.

For those who can recall, it was Mumbai Indians' Alzarri Joseph. The West Indian fast bowler, with his raw pace, had made a memorable first impression that evening and set a standard for future debutants. The IPL is full of surprises, but few have been as effective and record-breaking as Joseph's spell against Sunrisers Hyderabad in 2019.
