Kohli joint-fastest to 50 international tons

50 - Number of international hundreds for Virat Kohli. He became the eighth batsman overall and second Indian, after Sachin Tendulkar, to get there. Kohli got there in his 348th innings, in Kolkata on Monday, the joint-quickest along with Hashim Amla, who got there in February 2017.

2 - Number of third-innings centuries for Kohli in Tests. Both have come in successive third innings outings against Sri Lanka. The first was an unbeaten 103 in Galle earlier this year. Before these two knocks, Kohli averaged 27.12 in the third innings across 25 knocks, with four half-centuries. The last India captain to score a third-innings century before Kohli was Tendulkar, who did so against New Zealand in Mohali in 1999. The previous India player to score a third-innings century at Eden Gardens was Rahul Dravid, against Pakistan in 2005.

83 - Kohli's run tally across six Test innings at Eden Gardens before this century. He was out for single digits in four of those innings. In ODIs, he has a century and three fifties in six innings here.

119 - Balls taken by Kohli to score this century - his fastest of the 18 Test hundreds. The previous quickest was off 129 balls against New Zealand in Wellington in 2013-14. Kohli scored 68.87% of batsmen runs since he arrived to the crease - 104 out of 151 - at a strike rate of 87.39. While the other batsmen contributed 47 runs at strike rate of 31.92.

9 - Number of hundreds for Kohli across formats this year - three in Tests and six in ODIs - the most by him in any calendar year. He made eight hundreds, his previous best, in 2012 and 2014.

0 - No captain has made more international hundreds in a year than Kohli's nine this year. Ricky Ponting (2005 and 2006) and Graeme Smith (2006) also made nine hundreds. Kohli still has six internationals left this year to set a new record.

1 - Kohli is the first India captain to score a duck and a century in the same Test. He's the 18th captain overall to do so. Last India player to do so was Cheteshwar Pujara, also against Sri Lanka, in Colombo (SSC) in 2015. The last instance of an Indian doing this at home was Dravid, against England in Mohali in 2008.

Lehmanns can make it work - Alec Stewart

Over the coming days, when Australia's selection panel sits down to finalise the squad for their opening Ashes encounter in Brisbane, at some point during the conversation, Darren Lehmann will have to excuse himself from the room. If the name of his son, Jake Lehmann, comes up - and it almost certainly will, even as an outside choice - then senior Lehmann will leave the other selectors to deliberate without him.

While this process will be the result of a formal Cricket Australia Board directive to avoid conflicts of interest, it seems Darren Lehmann actively prefers not to be involved. "I'd be that nervous anyway I probably wouldn't be coach, I'd probably go to the bar," he said when the subject arose last year. Should Jake put on another good showing in this week's Sheffield Shield, the old man might have to come up with a coping strategy by the time Australia and England step out at the Gabba on November 23.

One former Ashes combatant who knows a fair bit about the father-son, coach-player dynamic, albeit from the English perspective, is Alec Stewart. England's second-most capped Test cricketer, Stewart began his international career in 1989, at a time when his dad, Micky, was manager of the team. Fortunately, they already had a well-established method for making the relationship work.

"When I signed professionally at Surrey as a 17-year-old, he was manager of the Surrey side then," Alec told ESPNcricinfo. "We'd obviously spoken about it, when I left school he knew I wanted to try and play cricket. He was only ever going to sign me if he felt I was good enough - he almost took the surname or the relationship out of the question, he just looked at me as a cricketer.

"That's what we made very, very clear. When we were at home, he's obviously me dad but when we were at cricket - or work, because that's what it was - then I didn't have a dad who was the coach and he didn't have a son who was a player. I was a player and he was very much coach, or manager. I never called him or referred to him as 'dad' when I was at work. Once we got home, or at a family occasion, he's dad and still is. But when we're at work it's very much a player-coach relationship."

Whether with Surrey or England, Micky was always "gur" (short for manager) to Alec, just as he was to everyone else. Although, he adds: "I might have called him a few other names under me breath if he dropped me."

The incredible rise of Jasprit Bumrah

It was Mohammed Siraj's international debut and he had been plundered for 10 and 16 in his first two overs. Siraj was at the receiving end of a merciless Colin Munro on a flat deck in Rajkot. When he finished his second over, Jasprit Bumrah walked up to him and put his arm round his shoulders to console him.

Bumrah tried to comfort Siraj, telling him every bowler gets hit and that they learn by getting hit. Bumrah is not the senior-most bowler in the Indian team; it's Bhuvneshwar Kumar. Bumrah still took the initiative to calm Siraj's nerves when he could have stayed back at his fielding position between overs. Bumrah himself is less than two years old in international cricket but he chose to take the responsibility upon himself, just the way he has as a bowler in the absence of more experienced quicks such as Umesh Yadav and Mohammed Shami.

On that day, it was primarily because of Bumrah that New Zealand did not race away to score over 200. He pulled the length back on the batting-friendly pitch when good-length balls and slower ones were being launched into the stands. In his second spell, he returned to stem the flow of boundaries in the death overs when Munro was "going berserk", in Bumrah's words, by giving away only 14 in his last two overs.

Bumrah has risen through the ranks at incredible pace and given the team management immense flexibility, allowing them to rely on him and Bhuvneshwar as their lead new-ball pair in both T20Is and ODIs while resting Shami and Umesh for the Test cricket. When he made his international debut in early 2016 in Australia, it was mainly his outlandish action and angle that deceived batsmen. Since then, players from around the world have had time to adjust to him - by now they have had 57 international matches to watch him in and try to pick up his weaknesses.

But Bumrah has been one step ahead. To add to the yorker he learnt from Mumbai Indians team-mate Lasith Malinga, he now possesses variations that include deceptive slower deliveries, in particular the offcutter. Within two years, he has emerged as the specialist death bowler India had desperately been seeking for many years.

"The kind of action he has, batsmen find it difficult to pick him, but he has also improved on a few things," Bhuvneshwar explained on the eve of the third T20I. "He has had a yorker, he has improved his slower deliveries too. When you bowl with such a bowler, you are confident that if you do well, he will also do well from the other end. If you aren't having a good day, at least he will bowl well. We feed off that confidence. The best part is before every match we talk to each other about the wicket and what strategy we can employ. That helps a lot."

Bumrah's package of skills was on display in Kanpur too, during the decisive third ODI when New Zealand were on track to chase down 338. Another flat track and Bhuneshwar was being taken to the cleaners. But Bumrah stepped up. He sent down some of his slower offcutters - removing Ross Taylor with one of them - and then defended 15 off the last over when dew made the ball difficult to control. Such was Virat Kohli's faith in him that Bumrah bowled four of the last 10 overs and he is relied upon to bowl his last two at the death in T20Is too. It reflects in how he has delivered more than one-third (34.37%) of the death overs bowled by Indian bowlers since his debut last year.

Being stingy as a bowler is one undebatable advantage but Bumrah has combined that with wickets. Only 10 months ago, England were chasing 146 in the Nagpur T20I and needed 41 from the last five overs, with Ben Stokes and Joe Root at the crease and seven wickets in hand. There was no Bhuvneshwar that day, but Bumrah had the wily old Ashish Nehra for company. Once Nehra dismissed Stokes, Bumrah bowled a combination of hit-the-deck back-of-a-length deliveries and slower balls that turned into four dot balls to Root and Jos Buttler in the 18th over.
