Abstract:
|
Batting average, home runs, and runs batted in have been the most dominant statistics to measure a baseball batter's performance. Since each of those contains a meaningful interpretation but also some drawback to explain a batter's ability at the same time, often we use those three together. Slugging percentage (SLG) and on-base percentage (OBP) have been used as alternatives of the traditional three statistics. SLG measures how often a batter hits and how valuable the hits are and OBP measures how often a batter reaches bases. Whereas SLG ignores reaching bases by hits by pitched ball or walks, OBP is limited to measure the quality of the hits. A combination of these two is called OPS, the sum of OBP and SLG, which has become more widely used. We introduced a variation of OPS, K, which is a single number explaining not only a batter's hitting performance but also his non-hitting perform
