#5 1915 Detroit Tigers
1915 marked the first time in Detroit Tigers franchise history that the team had at least 100 wins.
The 100 win club was led by a team that included Ty Cobb, Sam Crawford, and Bobby Veach in the outfield. The 1915 outfield has been regarded as the greatest outfield in baseball history.
Ty Cobb would steal 96 bases that year, an MLB record that would stand until 1962 when Maury Wills would steal 104 times.
The mound meanwhile was led by Hooks Dauss, who has the most wins in franchise history, Harry Coveleski, Jean Dubuc, and Bernie Boland.
The 100-win 1915 Tigers would go on to face the 101-win Boston Red Sox in the American League Pennant and would ultimately lose. The 1915 Tigers were also the first team to win at least 100 games without winning the pennant.
The 1915 team has the second highest winning percentage (.649) in franchise history, followed by the next team on our list-the 1934 Tigers (.656).
