Kolkata: Karnataka overcame early batting blues to lift the Vijay Hazare trophy by fashioning a four-wicket victory over Railways and complete a triple title triumph in the domestic cricket season here Sunday.

After restricting Railways to 157 in 47.4 overs, Karnataka seemed in a crisis at 47/5, but recovered to reach a winning 158/5 with 42 deliveries yet to be bowled at the sparsely crowded Eden Gardens.
