The 1996 season saw the rise of three Yankees who formed the core of the team for years to come: rookie shortstop Derek Jeter, second-year starting pitcher Andy Pettitte, and second-year pitcher Mariano Rivera, who served as setup man in 1996 before becoming closer in 1997. Aided by these young players, the Yankees won their first AL East title in 15 years. They defeated the Texas Rangers in the ALDS, and in ALCS beat the Baltimore Orioles 4–1, which included a notable fan interference by Jeffrey Maier that was called as a home run for the Yankees.
