| ABSTRACT | |||
| Batting performance measures containing strike rate adjustments
take into account the important fact that if two batsmen had scored the
same number of runs in a match, the one with the better strike rate had
performed best. But match conditions can influence the batting and bowling
performances of cricket players. On a good pitch a batsman can get a good
score at a high strike rate, but if the pitch was bad, a similar good score
is normally accompanied by a much lower strike rate. The main objective
of this study is to propose a method that can be used to make batsmen's
scores comparable despite the fact that playing conditions might have been
very different. The number of runs scored by a batsman is adjusted by comparing
his strike rate with the overall strike rate of all the players in the specific
match. These adjusted runs are then used in the most appropriate formula
to calculate the average of the batsman. The method is illustrated by using
the results of the Indian Premier League 2009 Twenty20 Series played during
May and June 2009. The main conclusion is that the traditional average is
not the most appropriate measure to compare batsmen's performances after
conclusion of a short series. Key words: Batting average, Indian Premier League, ratings, sports. |
