Answer
Three AL pennants were won by Connie Mack's Athletics with Hall of Famer Eddie Plank and future Hall of Famer Chief Bender leading the pitching staff. The Athletics won the pennants in 1902, 1905, and 1910. The 1902 pennant was the first in Athletics history, and the 1910 pennant was the last before the team moved to Philadelphia in 1955.
