Lee Mazzilli's journey in professional baseball began when he was drafted by the New York Mets in the first round of the 1973 Major League Baseball Draft. Born in Brooklyn, New York, Mazzilli quickly became a fan favorite due to his local roots and charismatic presence on the field. He made his major league debut with the Mets in 1976, showcasing his skills as an outfielder and switch-hitter.

Mazzilli's early years with the Mets were marked by his athleticism and ability to perform under pressure. In 1979, he was selected to the National League All-Star team, a testament to his growing reputation in the league. During the All-Star Game, Mazzilli hit a home run and drew a bases-loaded walk, helping the National League secure a victory. This performance solidified his status as a reliable player for the Mets.

In 1982, Mazzilli was traded to the Texas Rangers, marking the beginning of a series of moves that would see him play for several teams over the next few years. His time with the Rangers was short-lived, as he was traded to the New York Yankees later that year. Mazzilli's stint with the Yankees was followed by a move to the Pittsburgh Pirates in 1983. Despite the frequent changes in teams, Mazzilli continued to demonstrate his abilities as a consistent hitter and fielder.

Mazzilli returned to the Mets in 1986, a year that would prove to be memorable for the team. The Mets won the World Series that year, and Mazzilli played a role in their success, contributing as a valuable bench player. His return to New York was welcomed by fans who remembered his earlier years with the team.

After his second tenure with the Mets, Mazzilli played for the Toronto Blue Jays in 1989 before retiring as a player. His career statistics include a .259 batting average, 93 home runs, and 460 runs batted in. Mazzilli's ability to adapt to different teams and situations was a hallmark of his playing career.

Following his retirement as a player, Mazzilli transitioned into coaching and management roles. He served as a coach for the New York Yankees, where he was part of the staff that led the team to several playoff appearances. In 2004, Mazzilli was appointed as the manager of the Baltimore Orioles. His tenure with the Orioles lasted until 2005, during which he worked to develop the team's young talent.

Mazzilli's involvement in baseball extended beyond the field, as he became a broadcaster and analyst, sharing his insights and experiences with a wider audience. His knowledge of the game and engaging personality made him a respected figure in the baseball community.
