4. 1924 Washington Senators (92-62)
The 1924 Senators won the first pennant in franchise history behind Hall-of-Famers Walter Johnson (considered one of the best pitchers in baseball history), Sam Rice, and a young Goose Gosselin. Johnson won his second MVP and the Pitching Triple Crown, Rice hit .334, and Gosselin hit .344 and had 129 runs batted in (second in the MLB).
This team may not have had an elite record (there wouldn’t be a pennant winner with fewer wins until 1940), but they rode Johnson (also known as the “Big Train”) whenever they could, as the 36-year-old started a league-high 38 games. He went 23-7 and recorded six shoutouts (best in the MLB).
Johnson finished off a dramatic World Series against the New York Giants with the last four innings in the 12 inning Game Seven. The drama-filled win in game seven, the longest in baseball history, gave the franchise their only title in Washington.
This team had the more Hall of Fame players than any other in franchise history, as well as a championship attached to its name, but the second-worst record out of all the teams on this list holds them out of the top three slots.
