Cricketer-turned-commentator Sunil Gavaskar said Australia batter Steve Smith's hundred against India in the Brisbane Test "will act as an incentive" for ex-India captain Virat Kohli. "[In] fab four...when the man at this end (Smith) gets a good score...the man in the other camp (Kohli) will want to get a 100 [too]," he added. Smith scored 101(190) in Australia's first innings.
