Ravichandran Ashwin (91*) became the sixth Indian Test batsman to register an unbeaten score in the 90s. The others are Ajit Wadekar (91* in 1969), Gundappa Viswanath (97* in 1975), Dilip Vengsarkar (98* in 1985), Sourav Ganguly (98* in 2001) and Rahul Dravid (91* in 2004)
Alastair Cook in the first innings was run-out for the first time in his first-class career. In the second innings he was stumped for the only second time in his first-class career. The only other occasion also came in a Test match (st P. Jayawardene b R Herath for 106) at Lord's June 2011. For the record, the summary of Cook's first-class dismissals are: caught 196, lbw 63, bowled 25, stumped 2, run-out 1. Total innings 313 ( including 26 not outs).
India's first back-to-back Test losses at home since March 2000 when they lost to South Africa in Mumbai and Bangalore under the captaincy of Sachin Tendulkar.
England registered their sixth win in last seven Tests against India. It was their best sequence of wins against India since 1974-1977, when they won six in a row both in England and India. England also had won nine games out of 11 during the period 1952 to 1959.
From the Test series in England in July 2011, India's Test record reads: Matches 16, won 5, lost 10, drawn 1. Interestingly, the only drawn Test was in Mumbai against the West Indies in November 2011 which was a last ball draw!
Had England won in Calcutta by 10 wickets, it could have become the only third Test team after the West Indies (1985-86) and Australia (Nov. 1999) to win by this margin in successive Test matches. Incidentally, West Indies had actually won by that margin three times in a row in 1985-86.
