Sri Lanka's Bhanuka Rajapaksa smashed 50 to set up a seven-run win for Punjab Kings in their rain-hit opening Indian Premier League match against Kolkata Knight Riders on Saturday.

Bhanuka Rajapaksa on Sunday said Sri Lanka's cricket has proved a point to the world with their sixth Asia Cup title after his unbeaten 71 set up a commanding 23-run win over Pakistan.

Batsman Bhanuka Rajapaksa said Sri Lanka have shaken off their underdogs tag and proved they can challenge at next month's T20 World Cup, after beating India to stand on the verge of the Asia Cup final.

Kusal Mendis' fiery start and a key lower-order knock by Bhanuka Rajapaksa powered Sri Lanka to a four-wicket win over Afghanistan in their Asia Cup Super Four contest on Saturday.
