Klaasen hit the next ball for four, but then there was a stoppage when the object was flung at Super Giants batter Prerak Mankad, according to Jonty Rhodes.
Rhodes, the fielding coach of the Super Giants, tweeted that the object hit Mankad on the head while he was fielding close to the Super Giants dugout.
Speaking to the broadcaster after the innings, Klaasen said the episode broke the momentum of the Sunrisers batters, adding his criticism of the umpire.
“Disappointed in the audience. That’s not what you want from an audience. It broke a lot of momentum,” said Klaasen. “Hopefully the referees will stay consistent. Not a great referee.”
He was later fined 10% of his match money for breaking the IPL code of conduct. The official IPL statement did not specify the reason for the punishment, only saying: “Klaasen admitted to the Level 1 violation under Article 2.7 stating the use of public criticism/inappropriate comment in the IPL Code of Conduct.”
Klaasen scored 47 to help Sunrisers reach 182 after opting to bat. But half a century away from Mankad and explosive blows from Marcus Stoinis and Nicholas Pooran helped Super Giants win the game in the final.
