Alan Mills, a right-handed pitcher, made his presence felt in Major League Baseball primarily during the 1990s. Born on October 18, 1966, in Lakeland, Florida, Mills attended Kathleen High School before being drafted by the California Angels in the first round of the 1986 MLB Draft. His professional career began in the minor leagues, where he honed his skills and developed the pitching prowess that would later define his time in the majors.

Mills debuted in the major leagues with the New York Yankees on July 14, 1990. During his time with the Yankees, he served as a relief pitcher, a role he would continue to fulfill throughout his career. Although his stint with the Yankees was relatively brief, it provided him with the experience and exposure necessary to establish himself in the league.

In 1992, Mills was traded to the Baltimore Orioles, a move that marked a significant chapter in his career. With the Orioles, he became a reliable figure in their bullpen. Over the years, Mills developed a reputation for his ability to handle high-pressure situations, often being called upon in critical moments of the game. His tenure with the Orioles lasted until 1998, during which he became a familiar face to fans and a trusted arm for the team's managers.

Mills' time with the Orioles was highlighted by his participation in the 1996 and 1997 American League Championship Series. Although the Orioles did not advance to the World Series in those years, Mills' performances in the postseason underscored his ability to compete at a high level. His role as a middle reliever and setup man was crucial in bridging the gap between the starting pitchers and the closer, a task he executed with consistency.

In 1999, Mills returned to the Los Angeles Dodgers, the team that had originally drafted him, albeit under their previous name, the California Angels. His second stint with the Dodgers was short-lived, and he found himself back with the Orioles later that year. Mills continued to pitch for Baltimore until the end of his major league career in 2001.

Throughout his career, Mills was known for his fastball and slider combination, which he used effectively against both right-handed and left-handed hitters. His ability to maintain composure on the mound and deliver under pressure made him a valuable asset to the teams he played for. Over the course of his career, Mills appeared in 474 games, recording a win-loss record of 39-32, an earned run average (ERA) of 4.12, and 466 strikeouts.

After retiring as a player, Mills transitioned into coaching, sharing his knowledge and experience with younger players. His post-playing career included coaching roles within the Orioles' minor league system, where he continued to contribute to the sport he had dedicated much of his life to.
