da aviator aposta： Spin accounted for about 47% of the total balls bowled in this tournament, which was a huge increase from previous World Cups
da heads bet： S Rajesh04-Apr-2011Perhaps the most important difference between the 2011 World Cup and all the earlier ones was the role that spin played this time. It was always expected to be a key aspect, but what was surprising was the extent to which it dominated. Almost all the pitches in the tournament were slow – that’s the inherent nature of tracks in the subcontinent – but the fact that the tournament was played at the end of the Indian season, when many pitches had already been used for domestic cricket, probably added to the slowness of the wickets. Teams used spinners liberally to start the bowling and even at the death, while there were instances of teams going in with only one specialist seamer and three spinners.In all, spinners bowled 11,901 deliveries in this World Cup out of 25,425 balls bowled in the entire tournament. In percentage terms, that works out to 46.81, whereas in 2007, spin had contributed 8100 out of 25851 (31.33%). The percentage increase in balls bowled by spinners in 2011 over 2007 is almost 47% too, which is a huge jump too.A look at the spin numbers for the last seven World Cups reveals that this is the most spin-dominant, in terms of number of overs and the wickets taken by them. Not surprisingly, the two previous World Cups played in the subcontinent are the next-best, both in terms of percentage of balls bowled and wickets taken. In 1996, spinners bowled about 38% of the deliveries and took 41% of the wickets; this time, they bowled nearly 47% of all balls but took about 43% of the wickets.In terms of averages and run-rates, the numbers for spin aren’t very different from the overall tournament numbers: the spinners averaged 31.51 runs per wicket at an economy rate of 4.60 per over, while the overall tournament stats were 31.19 and 4.91.

India and Sri Lanka were the only sides to have a 50-plus average and a run-rate of more than five against spin. Among the batsmen who scored most runs against spin, six of the top seven were from these two sides – the only one outside of these teams was England’s Jonathan Trott, who also headed the list.However, India’s spin attack certainly wasn’t the best of the tournament, despite Yuvraj Singh’s superb display with the ball. They averaged more than 36 runs per wicket, and conceded almost five runs per over. Harbhajan Singh averaged more than 43 runs per wicket, while Yusuf Pathan took only one wicket in 35 overs. (Click here for India’s batting and bowling stats.)Pakistan’s spinners were the leading wicket-takers with 37, and they finished with an excellent average and economy rate too. Shahid Afridi was obviously their star spinner – he became the second spinner to lead the wickets tally in a World Cup, after Anil Kumble in 1996 – but he was also supported superbly by Mohammad Hafeez and Saeed Ajmal.The surprise package, in terms of spin quality, was clearly South Africa. The trio of Imran Tahir, Robin Peterson and Johan Botha was both incisive and economical, and their collective display was the main reason why so many experts had high expectations from this South African team.

Overall, too, Pakistan and South Africa were among the best bowling units – they were the top two in bowling averages and economy rates. South Africa conceded only one 250-plus score in the entire tournament – to India – while Sri Lanka conceded two and Pakistan three. The only team to concede five such totals were India – against Bangladesh, England, South Africa, Australia and Sri Lanka.However, while India’s bowling attack wasn’t the best in the tournament, their batting was surely the most explosive. They made seven 250-plus scores; Sri Lanka were the only other team to touch five. India’s run-rate of 5.79 was the best too, and they were one of only two sides to score more than 5.50 runs per over.

It was widely expected that this would be the first World Cup where the average runs per over would exceed five, and so it proved: the run-rate for the entire tournament was 5.03, which was a shade above 2007’s mark of 4.95. Despite this, though, it didn’t seem like a batsman-dominated World Cup, probably because there weren’t too many ridiculously high totals. Out of seventeen 300-plus scores this time, only three exceeded 340. In 2007, eight out of sixteen 300-plus scores were in excess of 340. In all, though, there were thirty-seven 250-plus totals in 49 matches in 2011, compared to 25 in 51 matches in 2007.

The overall run-rate of more than five was largely due to the fact that India hosted 60% of the matches. The run-rate in these matches was 5.23, while the matches played in Sri Lanka and Bangladesh had much lower scoring rates. Out of the seventeen 300-plus scores in the tournament, 12 came in India, four in Sri Lanka and only one in Bangladesh.

The Decision Review System was used 182 times in 49 games, which works out to an average of 3.71 times per game. The only match in which it wasn’t used at all was in the quarter-final between New Zealand and South Africa. At the other end of the scale was the game between Pakistan and Canada, when there were ten reviews, which was the highest of the tournament. Five of those appeals were upheld, which is also the highest in a single game.Of the 182 reviews, 37 times the on-field umpire’s original decision was changed, which means his call was upheld almost 80% of the time. The batting team used the review 78 times, of which 17 were successful (21.79%), while the corresponding percentage for the fielding team was 19.23 (20 out of 104).The team which used the DRS most effectively was South Africa, with five appeals upheld out of 13. They’re followed by three minnows, and then by Pakistan, who used the system more than any other side. The only side which didn’t get a single review correct was Ireland – all 11 of their appeals were struck down.

Simon Taufel was going well too, till his not-out decision against Thilan Samaraweera in the final was overturned when Yuvraj Singh asked for a review. Taufel finished with ten out of his 12 review appeals being struck down, a percentage of 83.33.The two umpires with the poorest review records were Asoka de Silva (five out of eight appeals upheld), and Daryl Harper (seven out of 14).
