So goes the circular logic by SI writer Cliff Corcoran, who notes that the Rays, Red Sox, and Our Astros are the only winless teams in baseball.
In major league history, which dates to 1871, 110 teams have started a season 0-5. Just two of those 110 went on to make the postseason, less than two percent...
...105 teams have started a season 5-0. Thirty-six of those teams went on to make the postseason (12 went on to win the World Series and six others played before the World Series was born in 1903), but another 27 finished in fourth place or below, with the other 42 finishing third or second but without claiming the wild card (when available).
