Al Leiter's journey through Major League Baseball is a tale of perseverance and skill. Born on October 23, 1965, in Toms River, New Jersey, Leiter grew up in a family with a strong baseball background. His older brother, Mark Leiter, also played in the major leagues, setting the stage for Al's future in the sport. Al Leiter's professional career began when he was drafted by the New York Yankees in the second round of the 1984 MLB Draft.

Leiter made his MLB debut with the Yankees on September 15, 1987. His early years in the majors were marked by challenges, including injuries that limited his playing time. Despite these setbacks, Leiter's potential was evident, and he continued to develop his skills as a left-handed pitcher. In 1989, he was traded to the Toronto Blue Jays, a move that would prove beneficial for his career.

With the Blue Jays, Leiter began to establish himself as a reliable pitcher. He was part of the team during their successful run in the early 1990s, contributing to their World Series victories in 1992 and 1993. Although he was not a regular starter during these championship seasons, his role as a spot starter and reliever was valuable to the team's overall success. His time in Toronto allowed him to refine his pitching techniques and gain confidence on the mound.

In 1996, Leiter signed with the Florida Marlins, where he truly began to shine as a starting pitcher. That year, he achieved a career milestone by throwing a no-hitter against the Colorado Rockies on May 11, 1996. This performance was a testament to his growth and ability to dominate opposing hitters. Leiter's tenure with the Marlins reached its peak in 1997 when he played a crucial role in leading the team to its first World Series title. His performance in the postseason, particularly in the National League Championship Series, was instrumental in the Marlins' success.

Following his time with the Marlins, Leiter joined the New York Mets in 1998. His arrival bolstered the Mets' pitching rotation, and he quickly became a fan favorite. Leiter's leadership and experience were invaluable to the Mets, and he played a significant role in guiding the team to the 2000 World Series. Although the Mets fell short against the Yankees, Leiter's performance throughout the season and postseason was commendable.

Leiter continued to pitch for the Mets until 2004, consistently delivering solid performances. In 2005, he returned to the Marlins for a brief stint before being traded back to the Yankees, where he finished his career. Throughout his time in the majors, Leiter was known for his competitive spirit and ability to pitch effectively in high-pressure situations. He was selected to two All-Star Games, in 1996 and 2000, and finished his career with a record of 162 wins, 132 losses, and an ERA of 3.80.

After retiring from playing, Leiter transitioned to a successful career in broadcasting, providing analysis and commentary for various networks.
