In 1916 — a decade and a half before the Dodgers nickname would stick to the Brooklyn franchise of the National League — Hall of Famer Rube Marquard posted a 1.58 earned-run average for the Brooklyn Robins. That remains the franchise record, even amid the excellence of Clayton Kershaw and Sandy Koufax.
After a century and a year, Marquard’s record could fall. Alex Wood has a 1.56 ERA.
However, Wood might not get the record even if his ERA does not rise.
