Jacques Kallis and Hashim Amla made the most of a placid first day wicket at Nagpur to score a century each and give their team a strong platform from which to reach 550 tomorrow and put India's severely depleted batting line up under pressure. India bowled reasonably well all day - they were accurate, but, if played patiently, posed no sustained threat to the batsman. It was a wicket on which the batsman can feel that he is "in", as they say.
Cricinfo now offers Hawkeye maps as part of their ball by ball coverage. While one ought to take Hawkeye with a pinch of salt, the beehive clusters that it shows are worth considering. Here are a few of these clusters on the first day. The fact that Amla and Kallis both made centuries helps us here as each India bowler bowled a number of deliveries at each batsman. Let's focus on each bowler bowling at Jacques Kallis.
Zaheer Khan

Ishant Sharma

Harbhajan Singh

Amit Mishra

Let's consider what each of these clusters mean. They tell the story of Kallis's innings, of the day's play. Each map gives us an insight into each bowler's method. Note that this map is a simulation of where each delivery passed the stumps at the batting end. As such all the problems with Hawkeye when it comes to LBW also apply here.
Zaheer Khan is by far the most skillful and most attacking bowler in the India bowling line up. His map has to be seen while taking into consideration the fact that he bowled from both round and over the wicket. He made the batsman play more often than the other bowlers on account of his angle. There was no swing on offer for Zaheer - he seems to have lost the inswinger to the right hander, and most of those deliveries ending up on middle stump or leg stump, were probably delivered from around the wicket.
Ishant Sharma cannot be as attacking as Zaheer Khan because he does not have the ability to attack the stumps consistently. He's very accurate as the map shows - he attacks the top of off stump consistently, but when there's no seam movement on offer, he's not unplayable. He has been trying to get close to the stumps as he bowls - hence his recent troubles with umpires about his follow through. But even so, his only method of getting a wicket is staying there and thereabouts on and outside off stumps - in the so-called "corridor of uncertainty". Except, given that his off cutter is not what it used to be, there isn't much uncertainty for the batsman outside off stump. Occasionally he does get the ball the straighten and it looks amazing - but most times, these deliveries are too good for the batsman - they don't even get the edge. Besides, these deliveries come only about two or three times a day. Ishant's length has been immaculate, but in order for him to be effective, he needs help from the wicket, especially against really good batsmen like Kallis. Ishant Sharma's method amounts to waiting for the batsman to make a mistake, but such is the standard of Test Cricket, that very often, there are batsmen like Kallis who see a good wicket and a good situation, and don't make a mistake all day.
Amit Mishra, the leg spinner bowled well on the first day - there was only a little bit of turn for him, and it was slow turn. Most of the runs he conceded were down to errors in length, or to misdirected googlied. Both batsmen appeared to have no trouble reading Mishra. Nevertheless, Mishra did beat both batsmen in flight on more than one occasion. It was a fairly conventional day for him.
Harbhajan Singh offers the most interesting pitch map. Despite his figures, he was the most accurate Indian bowler on show. But what does this accuracy mean? For a very long time now - almost for the whole of Harbhajan Singh's career, he has faced criticism from former players about various aspects of his bowling. Even in his most successful series against Australia in 2001, Erapalli Prasanna noted how few of Harbhajan Singh's dismissals were classical off-spinners dismissals. This pitch map indicated why. Harbhajan Singh's stock delivery would have passed over middle or leg stump, and for the most part was played down behind the wicket on the leg side by the batsman for a single. Harbhajan Singh conceded 40 singles and 6 twos - a total of 52 runs to the two batsmen - almost all of them without the batsman playing a shot in anger. Recently, Sanjay Manjrekar observed that Harbhajan Singh has stagnated as an off spinner in the last 3-4 years - since the year 2006, Harbhajan Singh has played 32 Tests for India in which he has taken 126 wickets at 37.07. No other bowler has complained more about wickets than Harbhajan Singh in the last 3-4 years.
Why is this happening? And what does the beehive map tell us about this? Harbhajan is basically trying to beat the batsman off the wicket and not in the air. On a slow wicket where the ball is not exactly spitting off the surface, this is unlikely to happen as good batsmen will have the chance to play him off the back foot. Further more, on the first day of a Test, he can't really bowl with a leg slip and a short leg, and he's basically bowling for one type of dismissal - caught short leg. Harbhajan Singh wants to get the batsman out on the defensive prod, not on the drive. This is consistent with the criticism of Harbhajan Singh by Prasanna for example, and also with Harbhajan's criticism of the wickets that India play on. There is something to both.
The idea that a spin bowler might lure a batsman - a top class Test batsman at that, into a drive, is a fiction for the most part. Most Test Match batsmen are too good to be beaten in the flight on a regular basis. Time is also a factor. Most batsmen don't need to drive the spinner all the time - players like Kallis are masters of the waiting game. Harbhajan knows this. The thing that is not in Harbhajan Singh's favor is that Jacques Kallis does not feel the need to disrupt the field that has been set for him. He is happy to play within a given field. It is here that the Captain comes into play.
But it is all very well for us to criticize both bowler and captain for not attacking more. To attack more is to invite the possibility of more runs being scored. One could argue that Harbhajan Singh should think of trying to get his wickets in more than one way - but this is easier said than done. It's much much harder to defeat a batsman in the flight than one might think. It is not merely a matter of getting the ball above the batsman's eye line. On a slow wicket, even if a batsman has been beaten in the flight, he still has the chance to recover, unless he is fatally committed to a stroke.
On days such as this at Nagpur, when a great batsman gives you no chance at all, it looks even worse. Harbhajan Singh did everything he was supposed to do on Day 1 - he bowled accurately, he bowled to his field (he was hit for one four on the off side all day), and yet he went for 81 runs off 21 overs. He needs to work out a way to concede fewer singles though. That is as much as matter of field setting as it is a matter of line and length. It is difficult to say whether Harbhajan Singh gets the field he wants, because he wants to bowl in a particular way (either from over or round the wicket), or he bowls to the field depending on how he is supposed to bowl. While he is not beating batsmen in the flight, his floater or straighter one are also ineffective. On a slightly quicker wicket, Harbhajan Singh's leg trap might be more effective. Against Kallis and Amla on a slow Day 1 wicket at Nagpur, it has looked ordinary.
There were a couple of games going on yesterday. West Zone chased 536 in the 4th innings against South Zone - Yusuf Pathan made 210*(190) to added to his 109(76) from the first innings to take West Zone to a 3 wicket win. A lot of people probably thought that that was a far more interesting and exciting game than the first day of the Test. And in many ways it probably was. But the quality of cricket in the Test Match was much much higher, and i don't refer to all the catches the South Zone dropped.
South Africa had the better of a high quality stalemate at Nagpur.
