Handing such good fortune to a batsman of his calibre at any time is an expensive habit. On a pitch as bland as this it is cricketing suicide, and England's bowlers were made to toil long and hard paying for Mike Atherton's folly. To add insult to some already injured pride, hardly a ball was missed and England's ploy of strengthening their bowling looked misguided.
Ganguly certainly thought so as he cut and drove England's attack to distraction. This is the 23-year-old Bengali's second Test and he celebrated by scoring a second century. It is an achievement that leaves the left- hander from Calcutta in some pretty esteemed company, and he joins the West Indians Lawrence Rowe and Alvin Kallicharran as the only other players to have scored successive hundreds in their first two Test innings.
One has perhaps come to expect big scores from Tendulkar, and yet considering Ganguly started this tour tagged as a token political selection made to appease the powerbrokers of Indian cricket in Calcutta, his form has been nothing short of a revelation. The people of Bengal have, at long last, a champion of their own to cheer. As India's most audacious cricket fans, they will have particularly enjoyed his cheeky six off Min Patel, from the penultimate over of the day. A shot that brought a swift rebuke from his partner who pointed to an imaginary watch on his wrist.
In between the milestones, spectators were treated to some sublime batting and there was little to choose between the hundreds. Apart from Tendulkar's early dose of good fortune - he also played a ball from Mark Ealham on to his stumps when he was 10 - there were no great anomalies in scoring rates, with Ganguly taking 22 balls more to reach three figures.
Both innings, however, were compiled with a grace and timing of shot that was both wristily Indian and yet somehow classically textbook as well. The pair left England helpless in their thrall and their unbeaten stand of 254 is the highest by either side so far in the series.
The duo complemented each other well and England's bowlers, especially Patel, were constantly being tested with the shifting line demanded to keep a right and left-handed batsmen batting together, in check. He was not the only one to struggle and, just after lunch, Tendulkar took such a liking to Dominic Cork, that he took 29 off 16 balls unleashing a thrilling array of off-side drives.
Cork's response was untypical and he immediately hobbled off to have a pesky toe nail clipped. In the morning, one of his overs had spanned 30 minutes, rain suspending play for twenty-nine of them, after his first ball had removed Vikram Rathore, caught behind by Jack Russell for four.
Soon after Chris Lewis had Nayan Mongia also held by Russell after an edged drive had rebounded off Graeme Hick at second slip. It was the same height as the chance Hick spilled at Lord's, though this time he had to go to his left, where something of a blind spot appears to exist.
England, who opted for Ealham instead of Ronnie Irani, could not have wished for a more decisive start. With the ball still hard, another wicket would have dented India's confidence and pushed them on to the back foot.
That chance came almost immediately, as Tendulkar cut uppishly at Lewis, sending the ball rocketing towards Atherton's thigh at gully. His anguish at spilling the chance was plain to see and it was not until Tendulkar was caught off a Cork no-ball just before the close that another mistake was made.
To be fair, on a blustery day England did not bowl all that badly and Lewis and Alan Mullally in particular bowled well in unhelpful circumstances. After lunch, the left-armer manfully got through an eight over spell without ever looking threatening. During such passages, unless a wicket looks likely, it is imperative for a captain to give his bowlers short sharp spells. Atherton did not and he let the game and his bowlers drift, with Ealham sending down just 12 overs.
The inclusion of Ealham was by all accounts a strongly debated decision. But whereas the Kent all-rounder celebrated his first day of Test cricket with a character-building 0-35, Irani was returned to the Essex side at Grace Road, where he fared little better, by scoring nought.
