Player stats

ERA 2018

Earned runs allowed per nine innings pitched. Lower ERA means fewer earned runs per inning.

Season

Minimum workload: one inning pitched per game. Completed seasons use the league's scheduled regular-season game count; seasons in progress use team games played. This is a general pitching minimum, not a relief-pitcher qualification rule. Data through December 31, 2018. Data refreshed Sep 12, 2026, 7:39 AM UTC.

ERA: Earned runs allowed per nine innings pitched. Lower ERA means fewer earned runs per inning.

Understanding ERA

Earned runs allowed per nine innings pitched. Lower ERA means fewer earned runs per inning.

Formula: 27 × ER ÷ outs recorded

Read rates alongside playing time. A small sample can produce an extreme result, and a missing value is different from zero.

Season rankings use regular-season records. A player has one combined row across teams; the team label identifies the associated team, not a separate team stint.
