In baseball statistics, hits per nine innings (denoted by H/9) is the average number of hits allowed by a pitcher in a nine inning period; calculated as: (hits allowed x 9) / innings pitched. [1] This is a measure of a pitcher's success based on the number of all outs he records.
Compared to a pitcher's batting average against, a pitcher's H/9 benefits from sacrifice bunts, double plays, runners caught stealing, and outfield assist, but it is hurt by some errors. Unlike batting average against, a pitcher's H/9 benefits from outs that are not related to official at bats, as they are recorded on runners after they have reached base.
As of June 2024 [update] , Nolan Ryan is the career leader (6.5553), Sandy Koufax is #2 (6.7916), Clayton Kershaw is #3 (6.8160). [2]

In baseball statistics, batting average against, also known as opponents' batting average, is a statistic that measures a pitcher's ability to prevent hits during official at bats. It can alternatively be described as the league's hitters' combined batting average against the pitcher.

In baseball statistics, earned run average (ERA) is the average of earned runs allowed by a pitcher per nine innings pitched. It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine. Thus, a lower ERA is better. Runs resulting from passed balls, defensive errors, and runners placed on base at the start of extra innings are recorded as unearned runs and omitted from ERA calculations.
