Ajay Rohera also became the highest individual run-scorer for Madhya Pradesh.
The wicket-keeper batsman Rohera's record-setting knock was laced with 21 boundaries and 5 hits over the fence. He had built his innings by 345 deliveries cautiously.
Rohera, apart from his match-winning knock which helped him set a new record in first-class cricket, also became the highest run-scorer for Madhya Pradesh.
The previous highest individual score overall record was held by JP Yadav, who had 265 runs to his name.
Madhya Pradesh, who were handed a huge boost by their debutant, are currently on second spot in the Elite Group A and B table after five matches, trailing to Saurashtra by a point.
