ERABA (Earned run average minus batting average) is a relatively new Sabermetric created by Bay Area baseball statistician Barry Hoffner. Assessment It is a general way of assessing how strong a team is performing on both defense (pitching) and offense (hitting). When two teams are facing each other, one basic way of predicting the outcomes is to compare their ERABA scores. ERABA is calculated by taking the team ERA multiplied by 100 and then subtracting the team batting average times 1000. An ERABA of under 100 is considered extraordinary. For example, the 2012 Washington Nationals had a team ERA of 3.33 and BA of .261, thus an ERABA of 72. In contrast, the 2012 Colorado Rockies had a team ERA of 5.22 and BA of .274, thus an ERABA of 248. Some statisticians prefer to look at ERABARISP, which compares ERA to Batting Average w/runners in scoring position, perhaps a better indicator of clutch hitting |
