 After struggling in recent months in the limited overs format, Karthik bounced back during the Challenger Trophy at the start of the Indian domestic season. Playing for India Blue, he made a duck in the first match, but then made 65 against India Green and an unbeaten 116 in the final to guide his team through a successful run-chase against India Red. He then rounded off his preparation for the next Test series with consecutive fifties for Tamil Nadu in the Ranji Trophy.
