Karun Nair continued his dream run with the bat, scoring an unbeaten century to help Vidarbha reach 264-6 on the opening day of their Ranji Trophy quarter-final against Tamil Nadu here on Saturday.

The 33-year-old Nair, who has been in stellar form, brought up his 22nd first-class century. This knock follows his century against Hyderabad in the previous round, and it adds to his four consecutive hundreds in the 50-over Vijay Hazare Trophy.
