Born in Saccarappa, Maine, Gore led the NL in several seasonal offensive categories. He won his only batting title in 1880 while playing for Chicago, along with league leading totals in on-base percentage and slugging percentage. He also led the league twice in runs scored, bases on balls three times, and games played by a center fielder once. Gore was also the all-time leader for most errors by major league outfielder upon his retirement with 368 total, including a record 346 errors in the National League, records he still holds today. (He made 217 errors for Chicago; 122 for New York; and seven for St. Louis, all National League teams; and 22 for the New York Giants of the Players' League.)
