Question: When was the last time a spinner bowled the first over of a Test match?
Spider says: This is a tough question, and for much of history, it is very hard to find. There were players that could bowl both at a decent level, and so it is difficult to know which method they bowled. Sobers has opened the bowling before, and could bowl both spin and pace, but the vast majority of the time, he would open with seam bowling.
On the other hand, there are a handful of people that defy classification, such as Sydney Barnes. Whether you characterize him as a spin bowler or fast bowler (likely he was neither - just a unique quantity) also plays into the situation. Even a bowler who normally bowls only spin might have opened the bowling once, but he might have tried his seam bowling while doing so.
The latest instance of a spinner opening the bowling (though in the second innings) was Muralitharan in 2007 against England in Galle. Kumble also opened the bowling in the second innings recently against Pakistan in 2007 at Kolkata, but he took the second over while the first was bowled by Zaheer Khan. Spinners opening the bowling in the third and fourth innings actually happens quite often in cricket, and was especially common for Indian spinners of the 1970s before the emergence of Kapil Dev.
Unfortunately, I could not find any instance of a modern spin bowler actually bowling the first ball of the first innings in a Test match.
Q: Who is really the best batsmen in the world?
A :To judge this accurately, an objective method must be developed. The official one is pretty good, as it takes into account the opposition, the conditions and the amount of scoring, and with that criteria K.C. Sangakkara is the highest rated, followed by Kallis, Hussey and Ponting. It's hard to deny Sangakkara, with the amount of double centuries he has scored recently.
