What is the knuckleball, on which Tye took 4 of 5 wickets?
Gujarat Lions pacer Andrew Tye, who became the first bowler to take a hat-trick and five-for on IPL debut, took four of his five wickets on knuckleballs. A knuckleball is a slower delivery, often referred "unhittable" because of its unpredictable movement. It is gripped at the fingertips and pitched in a manner so as to eliminate spin on the ball.
