The last league match of the on-going IPL tournament will be played at Kolkata tonight. The fixture is between Kolkata Knight Riders and Mumbai Indians.The four semi-final places are almost decided. Yet, the Kolkata team have only a remote chance of qualifiying if they beat table-toppers Mumbai Indians by a very big margin. For that, they will have to improve their net run rate of 0.456 to the extent that they overhaul the net-run rate of fourth-placed Royal Challengers Bangalore.
