Run: A "run" or "sequence" is a set of 3 or more cards of consecutive ranks (irrespective💰 of suit) - such as 9-10-jack or 2-3-4-5. Note that ace is low so for example ace-king-queen is not a💰 run. The player of a card which completes a run scores for the run; the score is equal to the💰 number of cards in the run.

Earned runs is the key counting statistic used in ERA, the most widely💰 accepted barometer of a pitcher's success. If there are no errors or passed balls in a given inning or game,💰 all the runs in that inning or game are earned runs.
