All stats till the end of the group stages of the ICC World Twenty20, i.e, till May 5.
In the lead-up to the ICC World Twenty20, what was generally agreed upon was that the pitches in the West Indies would greatly assist spin, and that spinners would be far more difficult to get away than fast bowlers. Intuitively that seems a reasonable assessment, as the pitches have lost much of their pace at most venues there. Add to that the fairly large outfields, which generally help spinners get batsmen out caught in the deep, and it's fair to assume that spinners will enjoy the conditions more than the fast men.
What's transpired so far - till the end of the group stage - though, is quite different. Spinners haven't done badly, taking 50 wickets at a decent average and economy rate, but they've been upstaged by the fast bowlers. In the first 12 matches in the World Twenty20, medium pace or pace has taken 90 out of the 140 wickets that have fallen to bowlers, at an average of 17. The three leading wicket-takers - Dirk Nannes, Mohammad Aamer and Darren Sammy - are all from that category, with all of them averaging fewer than 10 runs per wicket. Hamid Hassan of Afghanistan and Shaun Tait have sub-ten averages as well.
On the other hand, while some spinners like Daniel Vettori and Shakib Al Hasan have done well, several others have had less success than anticipated. Yusuf Pathan and Mohammad Hafeez are among those with economy rates of more than 10 runs per over. And the ploy of opening the bowling with spin hasn't met with much success either: on the 11 occasions when they've bowled the first or second over of an innings, spinners have gone for 70 runs without taking a single wicket.
Pace and spin in the 2010 ICC World Twenty20 Wickets Average Economy rate Strike rate
Pace 90 17.06 7.02 14.5
Spin 50 26.72 7.22 22.2
The performances of pace and spin so far in the World Cup are a departure from their overall records in Twenty20 internationals. In all matches, pace- or medium-pace bowlers average 23.76 runs per wicket and concede 7.53 runs per over; the corresponding numbers for spinners are 20.77 and 6.76. Doing the same analysis for matches featuring only the top 10 teams (excluding the Associate countries), the difference is still similar: fast bowlers concede more runs per wicket and per over compared to spinners.
One of the reasons for this could be the period of the innings when these bowlers are used: fast bowlers have usually bowled the first few and the last few overs of 20-over games, when batsmen are more inclined to take chances. However, the good performances of spinners in a format in which it was initially feared they'd have no role has encouraged captains to use them more often in difficult periods. That trend was noticeable during the IPL, and it's likely to continue in internationals as well.
