Written off by some pundits as he went into the series against Australia with an average of 22.96, Ganga said he has learnt a lot from his earlier frustrations.
"I always knew I had the ability and capability to score at this level," he told reporters on Monday after scoring 117 to help the West Indies avoid the follow-on in the second Test. He was eventually caught at first slip by Matthew Hayden off paceman Brett Lee.
