Who was the only team in the MLB to win over 100 regular season games for 2011?

The Philadelphia Phillies were the only MLB team to win more than 100 regular-season games in 2011, finishing 102–60.

That record gave Philadelphia the best mark in baseball and the National League East title. The team was led by a celebrated starting rotation featuring Roy Halladay, Cliff Lee, Roy Oswalt, and Cole Hamels, supported by stars such as Ryan Howard, Chase Utley, and Jimmy Rollins. The Phillies also posted a remarkable 20–5 record in September and October before the postseason began.

Their dominant regular season did not lead to a championship. Philadelphia lost the National League Division Series to the St. Louis Cardinals, three games to two. St. Louis went on to defeat the Texas Rangers in the World Series.

The phrase “over 100” means at least 101 wins, so a 100–62 team would not qualify. Philadelphia’s 102 victories made it the lone club above that threshold in 2011.
