ERA+ is a measure of a pitcher's ERA adjusted for the effects of the ballpark they pitch in and the league average ERA. It is calculated using a complex formula that takes into account the league ERA, the player's ERA, and the park factor.
ERA+ takes a player's earned run average (ERA) and normalizes it across the entire league. It accounts for external factors like ballparks and opponents. A score of 100 is league average, and 150 is 50 percent better than the league average.
Adjusted ERA+, often simply abbreviated to ERA+ or ERA plus, is a pitching statistic in baseball. It adjusts a pitcher's earned run average (ERA) according to the pitcher's ballpark (in case the ballpark favors batters or pitchers) and the ERA of the pitcher's league.
