Morphology
The phrase transparently combines 'earned' + 'run' + 'average', so a learner who knows the words can infer it refers to an average related to runs that are considered 'earned' rather than unearned. However, the exact baseball-specific sense and calculation (e.g. per nine innings and the technical distinction between earned vs. unearned runs) require sport-domain knowledge, so the meaning is not fully derivable from the constituents alone.
Etymology
Earned run average is a baseball number that comes from a simple picture: you count the runs a pitcher is really to blame for — the earned run — and turn that into a single number, the average, for a full game. So it shows how many 'earned runs' a 'pitcher' would allow over 'nine innings', which makes it easy to compare pitchers.
