Controversy over Smith's live chat during India T20

Sydney: The use of on-field microphones by players in Twenty20 matches came under fire Wednesday after star Australian batsman Steve Smith lost his wicket while commentating during a game against India.

Smith was answering questions from broadcaster Channel Nine's commentators while he was in the middle with Aaron Finch as Australia chased down India's 188 runs during Tuesday's match at Adelaide Oval.

Shortly after speaking, Smith chipped Ravindra Jadeja and was caught at extra cover by Virat Kohli for 21, with the star Indian batsman making a "chatterbox" hand gesture at the Test captain.

Australia fans slammed Channel Nine on Twitter, blaming the commercial station for distracting Smith, while others said Kohli's gesture was a criticism of live chat during a game.

T20, a quick-fire, high-octane format, was designed to draw crowds to tournaments amid fears that spectators were tiring of longer formats such as five-day Tests.

Sports writer Robert Craddock said Smith's dismissal raised the question of whether the T20 short-form structure was meant to be a carnival or a contest.

"Did it cost Australia the game? Possibly. If it happened in a Test match I would be punching a hole in my keyboard protesting at the farce of it all," he wrote in Brisbane's Courier Mail.

"But it was T20 international and like the rest of the world, I am still trying to work out what these games actually mean."
