Karun Nair's unbeaten 132 helps Vidarbha take a commanding lead of 286 runs over Kerala in the Ranji Trophy final. After being dropped by Kerala's Akshay Chandran, Nair's century, along with Danish Malewar's 73, steadied Vidarbha after early blows. The pair's 182-run partnership puts Vidarbha in a strong position for the final day.
