Stats highlights from the first 12 days of IPL 2012

S Rajesh and Madhusudhan Ramakrishnan16-Apr-2012One aspect that has stood out in IPL 2012 so far has been the extent to which bowlers have dominated. Of the 18 matches so far, 17 have been 20-over games, and in seven of those matches the team batting first has finished with a score of less than 140. Only once has the team batting first topped 200 (and ironically, Royal Challengers Bangalore couldn’t defend that total, against Chennai Super Kings).The table below compares the stats in the first 12 days of each of the five IPL seasons so far, and it’s clear from the numbers below that the batsmen haven’t been having it all their way. The overall run-rate so far this year is 7.59, which is exactly what the rate was after 12 days of IPL 2009, when the tournament was played in more bowler-friendly conditions in South Africa. Among all the editions played in India, the run-rate so far is clearly the lowest this season: in 2008 and 2010, the rates were more than eight per over, while it 2011 it was 7.98 after 12 days of comeptition. Even the current rate this year is thanks to the last four days, when Royal Challengers and Super Kings both scored more than 200, and Rajasthan Royals fell only five short of the mark.In terms of averages, this year’s 21.41 falls marginally below the 2009 mark of 21.83 at the same stage of the tournament, and well below the averages achieved in the three previous editions which were held in India. Last year, the average was 30.23, with 29 fifties and two hundreds in 19 games; this year, after 18, the fifties and hundreds are about half that number. The 20-over format is meant to be a run-fest with batsmen calling the shots, but this year the bowlers, with their clever variations in pace and length, have made life pretty difficult for batsmen. The pitches in some of the venues – slow and low in Kolkata, green and seamer-friendly in Mohali – have further added to the batting woes.

In the early part of last season, batting first was a wretched option – only five of the first 19 matches were won by the team defending a total. (By the end of the tournament last year, the teams batting first had a 32-40 win-loss record.) This year, teams batting first have done much better, winning ten out of 18 matches.However, captains have struggled to make the right call after winning the toss this year: only six out of 18 games have been won by the team which won the toss. In the last three seasons, the team winning the toss had won more matches than they’d lost. This season, many captains have continued to field first after winning the toss, but without much success – out of the 12 times when they’ve fielded first, they’ve won only four games.

As it turned out, spinners have held their own very well, and are increasingly playing a bigger role in matches, especially in conditions which aid slow bowling. The stats for pace and spin over the five seasons indicates that spinners are bowling more overs every season: in the first 16 matches in 2008 they contributed just 22% of the overs; in 2012, that percentage has risen to almost 41%. Their contribution of wickets has increased more modestly, but their bigger contribution has been in keeping the runs in check – their economy rate has been better than that of the fast and medium-fast bowlers in every season.
