WHICH TEAM HAS THE RECORD FOR MOST WINS IN A SEASON?
The record for the most wins in a season is held by the 1906 Chicago Cubs and the 2001 Seattle Mariners who both won a total of 116 wins. The Cubs did it over a 152 game season (0.763 Win %) while the Mariners did it over a 162 game season (0.716 Win %).

With the Mariners failing to win the World Series after 116 regular season wins, how do 100+ win teams fare when it comes to winning it all?
HOW OFTEN DO 100+ WIN SEASON TEAMS END UP WINNING THE WORLD SERIES?
In the World Series era, there have been a total of 93 100+ win seasons and out of these 93 seasons only 34 of the teams went on to win the World Series or 36.6% of the time.
For some teams, like the Cincinnati Reds and New York Yankees, getting 100+ wins during the regular seasons has been a good sign for their World Series chances (Reds won 3/4 while Yankees won 12/19). On the other hand, for the Atlanta Braves have had six 100+ win seasons but never won a World Series in any of those seasons, it hasn’t been a good indicator.
Here is each teams 100+ win record during the World Series era and the number of times they also won the World Series in those seasons:
|Team||World Series Era (100+ Wins)||Also Won World Series||World Series Win %|
|New York Yankees||19||12||63%|
|St. Louis Cardinals||8||4||50%|
|San Francisco Giants||7||1||14%|
|Los Angeles Dodgers||5||0||0%|
|Boston Red Sox||3||2||67%|
|New York Mets||3||2||67%|
|Chicago White Sox||1||1||100%|
|Kansas City Royals||1||0||0%|
|Los Angeles Angels||1||0||0%|
But not every team has had a 100+ win season in their history.
