Missing a historic triple century milestone by just one run will remain a "lifetime disappointment", but Bengal opener Sudip Kumar Gharami says the heartbreak has strengthened his resolve to stay focused in every situation.

Sudip Kumar Gharami smashed an incredible 299 for Bengal against Andhra in their Ranji Trophy quarter-final clash.

Riding on half-centuries from opener Yash Dubey and Rajat Patidar, defending champions Madhya Pradesh completed their remarkable fightback as they beat Andhra by five wickets to enter the Ranji Trophy semifinals in Indore on Friday.
