Every team to start the season 10-0 or better in MLB history

Brooklyn Dodgers, 1955 (10)

The Dodgers had previously held the longest record entering the season, following a 9-0 run to start the 1940 campaign. Tied with only the New York Giants at the time for the record, the Dodgers early stretch in 1955 quickly etched their name alone at the top with their 10-0 opening. Led by the likes of Roy Campanella, Carl Furillo and Duke Snider, the team’s offense powered them to the only World Series win on this list.
